The Anatomy of Melancholy Part 12

[882] ------"macies, et nova febrium Terris incubit cohors."

For besides many epidemical diseases unheard of, and altogether unknown to Galen and Hippocrates, as s...o...b..tum, small-pox, plica, sweating sickness, morbus Gallicus, &c., we have many proper and peculiar almost to every part.

_No man free from some Disease or other_.] No man amongst us so sound, of so good a const.i.tution, that hath not some impediment of body or mind.

_Quisque suos patimur manes_, we have all our infirmities, first or last, more or less. There will be peradventure in an age, or one of a thousand, like Zenophilus the musician in [883]Pliny, that may happily live 105 years without any manner of impediment; a Pollio Romulus, that can preserve himself [884]"with wine and oil;" a man as fortunate as Q. Metellus, of whom Valerius so much brags; a man as healthy as Otto Herwardus, a senator of Augsburg in Germany, whom [885]Leovitius the astrologer brings in for an example and instance of certainty in his art; who because he had the significators in his geniture fortunate, and free from the hostile aspects of Saturn and Mars, being a very cold man, [886]"could not remember that ever he was sick." [887]Paracelsus may brag that he could make a man live 400 years or more, if he might bring him up from his infancy, and diet him as he list; and some physicians hold, that there is no certain period of man's life; but it may still by temperance and physic be prolonged. We find in the meantime, by common experience, that no man can escape, but that of [888]Hesiod is true:

"[Greek: pleiae men gar gaia kakon, pleiae de thala.s.sa, nousoid' anthropoi ein eph' haemerae, aed' epi nukti Hautomatoi phoitosi.]"------

"Th' earth's full of maladies, and full the sea, Which set upon us both by night and day."

_Division of Diseases_.] If you require a more exact division of these ordinary diseases which are incident to men, I refer you to physicians; [889]they will tell you of acute and chronic, first and secondary, lethals, salutares, errant, fixed, simple, compound, connexed, or consequent, belonging to parts or the whole, in habit, or in disposition, &c. My division at this time (as most befitting my purpose) shall be into those of the body and mind. For them of the body, a brief catalogue of which Fuschius hath made, _Inst.i.tut. lib. 3, sect. 1, cap. 11._ I refer you to the voluminous tomes of Galen, Areteus, Rhasis, Avicenna, Alexander, Paulus Aetius, Gordonerius: and those exact Neoterics, Savanarola, Capivaccius, Donatus Altomarus, Hercules de Saxonia, Mercurialis, Victorius Faventinus, Wecker, Piso, &c., that have methodically and elaborately written of them all. Those of the mind and head I will briefly handle, and apart.

SUBSECT. III.--_Division of the Diseases of the Head_.

These diseases of the mind, forasmuch as they have their chief seat and organs in the head, which are commonly repeated amongst the diseases of the head which are divers, and vary much according to their site. For in the head, as there be several parts, so there be divers grievances, which according to that division of [890]Heurnius, (which he takes out of Arcula.n.u.s,) are inward or outward (to omit all others which pertain to eyes and ears, nostrils, gums, teeth, mouth, palate, tongue, weezle, chops, face, &c.) belonging properly to the brain, as baldness, falling of hair, furfur, lice, &c. [891]Inward belonging to the skins next to the brain, called _dura_ and _pia mater_, as all headaches, &c., or to the ventricles, caules, kells, tunicles, creeks, and parts of it, and their pa.s.sions, as caro, vertigo, incubus, apoplexy, falling sickness. The diseases of the nerves, cramps, stupor, convulsion, tremor, palsy: or belonging to the excrements of the brain, catarrhs, sneezing, rheums, distillations: or else those that pertain to the substance of the brain itself, in which are conceived frenzy, lethargy, melancholy, madness, weak memory, sopor, or _Coma Vigilia et vigil Coma_. Out of these again I will single such as properly belong to the phantasy, or imagination, or reason itself, which [892]Laurentius calls the disease of the mind; and Hildesheim, _morbos imaginationis, aut rationis laesae_, (diseases of the imagination, or of injured reason,) which are three or four in number, frenzy, madness, melancholy, dotage, and their kinds: as hydrophobia, lycanthropia, _Chorus sancti viti, morbi daemoniaci_, (St. Vitus's dance, possession of devils,) which I will briefly touch and point at, insisting especially in this of melancholy, as more eminent than the rest, and that through all his kinds, causes, symptoms, prognostics, cures: as Lonicerus hath done _de apoplexia_, and many other of such particular diseases. Not that I find fault with those which have written of this subject before, as Jason Pratensis, Laurentius, Montaltus, T. Bright, &c., they have done very well in their several kinds and methods; yet that which one omits, another may haply see; that which one contracts, another may enlarge. To conclude with [893]Scribanius, "that which they had neglected, or perfunctorily handled, we may more thoroughly examine; that which is obscurely delivered in them, may be perspicuously dilated and amplified by us:" and so made more familiar and easy for every man's capacity, and the common good, which is the chief end of my discourse.

SUBSECT. IV.--_Dotage, Frenzy, Madness, Hydrophobia, Lycanthropia, Chorus sancti Viti, Extasis_.

_Delirium, Dotage_.] Dotage, fatuity, or folly, is a common name to all the following species, as some will have it. [894]Laurentius and [895]

Altomarus comprehended madness, melancholy, and the rest under this name, and call it the _summum genus_ of them all. If it be distinguished from them, it is natural or ingenite, which comes by some defect of the organs, and overmuch brain, as we see in our common fools; and is for the most part intended or remitted in particular men, and thereupon some are wiser than others: or else it is acquisite, an appendix or symptom of some other disease, which comes or goes; or if it continue, a sign of melancholy itself.

_Frenzy_.] _Phrenitis_, which the Greeks derive from the word [Greek: phraen], is a disease of the mind, with a continual madness or dotage, which hath an acute fever annexed, or else an inflammation of the brain, or the membranes or kells of it, with an acute fever, which causeth madness and dotage. It differs from melancholy and madness, because their dotage is without an ague: this continual, with waking, or memory decayed, &c.

Melancholy is most part silent, this clamorous; and many such like differences are a.s.signed by physicians.

_Madness_.] Madness, frenzy, and melancholy are confounded by Celsus, and many writers; others leave out frenzy, and make madness and melancholy but one disease, which [896]Jason Pratensis especially labours, and that they differ only _secundam majus_ or _minus_, in quant.i.ty alone, the one being a degree to the other, and both proceeding from one cause. They differ _intenso et remisso gradu_, saith [897]Gordonius, as the humour is intended or remitted. Of the same mind is [898]Areteus, Alexander Tertullia.n.u.s, Guianerius, Savanarola, Heurnius; and Galen himself writes promiscuously of them both by reason of their affinity: but most of our neoterics do handle them apart, whom I will follow in this treatise. Madness is therefore defined to be a vehement dotage; or raving without a fever, far more violent than melancholy, full of anger and clamour, horrible looks, actions, gestures, troubling the patients with far greater vehemency both of body and mind, without all fear and sorrow, with such impetuous force and boldness, that sometimes three or four men cannot hold them. Differing only in this from frenzy, that it is without a fever, and their memory is most part better. It hath the same causes as the other, as choler adust, and blood incensed, brains inflamed, &c. [899]Fracastorius adds, "a due time, and full age" to this definition, to distinguish it from children, and will have it confirmed impotency, to separate it from such as accidentally come and go again, as by taking henbane, nightshade, wine, &c.

Of this fury there be divers kinds; [900]ecstasy, which is familiar with some persons, as Cardan saith of himself, he could be in one when he list; in which the Indian priests deliver their oracles, and the witches in Lapland, as Olaus Magnus writeth, _l. 3, cap. 18._ _Extasi omnia praedicere_, answer all questions in an ecstasis you will ask; what your friends do, where they are, how they fare, &c. The other species of this fury are enthusiasms, revelations, and visions, so often mentioned by Gregory and Bede in their works; obsession or possession of devils, sibylline prophets, and poetical furies; such as come by eating noxious herbs, tarantulas stinging, &c., which some reduce to this. The most known are these, lycanthropia, hydrophobia, chorus sancti Viti.

_Lycanthropia_.] Lycanthropia, which Avicenna calls _cucubuth_, others _lupinam insaniam_, or wolf-madness, when men run howling about graves and fields in the night, and will not be persuaded but that they are wolves, or some such beasts. [901]Aetius and [902]Paulus call it a kind of melancholy; but I should rather refer it to madness, as most do. Some make a doubt of it whether there be any such disease. [903]Donat ab Altomari saith, that he saw two of them in his time: [904]Wierus tells a story of such a one at Padua 1541, that would not believe to the contrary, but that he was a wolf.

He hath another instance of a Spaniard, who thought himself a bear; [905]Forrestus confirms as much by many examples; one amongst the rest of which he was an eyewitness, at Alcmaer in Holland, a poor husbandman that still hunted about graves, and kept in churchyards, of a pale, black, ugly, and fearful look. Such belike, or little better, were king Praetus'

[906]daughters, that thought themselves kine. And Nebuchadnezzar in Daniel, as some interpreters hold, was only troubled with this kind of madness.

This disease perhaps gave occasion to that bold a.s.sertion of [907]Pliny, "some men were turned into wolves in his time, and from wolves to men again:" and to that fable of Pausanias, of a man that was ten years a wolf, and afterwards turned to his former shape: to [908]Ovid's tale of Lycaon, &c. He that is desirous to hear of this disease, or more examples, let him read Austin in his 18th book _de Civitate Dei, cap. 5._ Mizaldus, _cent. 5.

77._ Sckenkius, _lib. 1._ Hildesheim, _spicel. 2. de Mania_. Forrestus _lib. 10. de morbis cerebri._ Olaus Magnus, Vincentius Bellavicensis, _spec. met. lib. 31. c. 122._ Pierius, Bodine, Zuinger, Zeilger, Peucer, Wierus, Spranger, &c. This malady, saith Avicenna, troubleth men most in February, and is nowadays frequent in Bohemia and Hungary, according to [909]Heurnius. Scheretzius will have it common in Livonia. They lie hid most part all day, and go abroad in the night, barking, howling, at graves and deserts; [910]"they have usually hollow eyes, scabbed legs and thighs, very dry and pale," [911]saith Altomarus; he gives a reason there of all the symptoms, and sets down a brief cure of them.

_Hydrophobia_ is a kind of madness, well known in every village, which comes by the biting of a mad dog, or scratching, saith [912]Aurelia.n.u.s; touching, or smelling alone sometimes as [913]Sckenkius proves, and is incident to many other creatures as well as men: so called because the parties affected cannot endure the sight of water, or any liquor, supposing still they see a mad dog in it. And which is more wonderful; though they be very dry, (as in this malady they are) they will rather die than drink: [914]de Venenis Caelius Aurelia.n.u.s, an ancient writer, makes a doubt whether this Hydrophobia be a pa.s.sion of the body or the mind. The part affected is the brain: the cause, poison that comes from the mad dog, which is so hot and dry, that it consumes all the moisture in the body. [915]

Hildesheim relates of some that died so mad; and being cut up, had no water, scarce blood, or any moisture left in them. To such as are so affected, the fear of water begins at fourteen days after they are bitten, to some again not till forty or sixty days after: commonly saith Heurnius, they begin to rave, fly water and gla.s.ses, to look red, and swell in the face, about twenty days after (if some remedy be not taken in the meantime) to lie awake, to be pensive, sad, to see strange visions, to bark and howl, to fall into a swoon, and oftentimes fits of the falling sickness. [916]

Some say, little things like whelps will be seen in their urine. If any of these signs appear, they are past recovery. Many times these symptoms will not appear till six or seven months after, saith [917]Codronchus; and sometimes not till seven or eight years, as Guianerius; twelve as Albertus; six or eight months after, as Galen holds. Baldus the great lawyer died of it: an Augustine friar, and a woman in Delft, that were [918]Forrestus'

patients, were miserably consumed with it. The common cure in the country (for such at least as dwell near the seaside) is to duck them over head and ears in sea water; some use charms: every good wife can prescribe medicines. But the best cure to be had in such cases, is from the most approved physicians; they that will read of them, may consult with Dioscorides, _lib. 6. c. 37_, Heurnius, Hildesheim, Capivaccius, Forrestus, Sckenkius and before all others Codronchus an Italian, who hath lately written two exquisite books on the subject.

_Chorus sancti Viti_, or St. Vitus's dance; the lascivious dance, [919]

Paracelsus calls it, because they that are taken from it, can do nothing but dance till they be dead, or cured. It is so called, for that the parties so troubled were wont to go to St. Vitus for help, and after they had danced there awhile, they were [920]certainly freed. 'Tis strange to hear how long they will dance, and in what manner, over stools, forms, tables; even great bellied women sometimes (and yet never hurt their children) will dance so long that they can stir neither hand nor foot, but seem to be quite dead. One in red clothes they cannot abide. Music above all things they love, and therefore magistrates in Germany will hire musicians to play to them, and some l.u.s.ty st.u.r.dy companions to dance with them. This disease hath been very common in Germany, as appears by those relations of [921]Sckenkius, and Paracelsus in his book of Madness, who brags how many several persons he hath cured of it. Felix Plateras _de mentis alienat. cap. 3_, reports of a woman in Basil whom he saw, that danced a whole month together. The Arabians call it a kind of palsy. Bodine in his 5th book _de Repub. cap. 1_, speaks of this infirmity; Monavius in his last epistle to Scoltizius, and in another to Dudithus, where you may read more of it.

The last kind of madness or melancholy, is that demoniacal (if I may so call it) obsession or possession of devils, which Platerus and others would have to be preternatural: stupend things are said of them, their actions, gestures, contortions, fasting, prophesying, speaking languages they were never taught, &c. Many strange stories are related of them, which because some will not allow, (for Deacon and Darrel have written large volumes on this subject pro and con.) I voluntarily omit.

[922]Fuschius, _Inst.i.tut. lib. 3. sec. 1. cap. 11_, Felix Plater, [923]Laurentius, add to these another fury that proceeds from love, and another from study, another divine or religious fury; but these more properly belong to melancholy; of all which I will speak [924]apart, intending to write a whole book of them.

SUBSECT. V.--_Melancholy in Disposition, improperly so called, Equivocations_.

Melancholy, the subject of our present discourse, is either in disposition or habit. In disposition, is that transitory melancholy which goes and comes upon every small occasion of sorrow, need, sickness, trouble, fear, grief, pa.s.sion, or perturbation of the mind, any manner of care, discontent, or thought, which causeth anguish, dullness, heaviness and vexation of spirit, any ways opposite to pleasure, mirth, joy, delight, causing frowardness in us, or a dislike. In which equivocal and improper sense, we call him melancholy that is dull, sad, sour, lumpish, ill disposed, solitary, any way moved, or displeased. And from these melancholy dispositions, [925]no man living is free, no stoic, none so wise, none so happy, none so patient, so generous, so G.o.dly, so divine, that can vindicate himself; so well composed, but more or less, some time or other he feels the smart of it. Melancholy in this sense is the character of mortality. [926]"Man that is born of a woman, is of short continuance, and full of trouble." Zeno, Cato, Socrates himself, whom [927]Aelian so highly commends for a moderate temper, that "nothing could disturb him, but going out, and coming in, still Socrates kept the same serenity of countenance, what misery soever befell him," (if we may believe Plato his disciple) was much tormented with it. Q. Metellus, in whom [928]Valerius gives instance of all happiness, "the most fortunate man then living, born in that most flouris.h.i.+ng city of Rome, of n.o.ble parentage, a proper man of person, well qualified, healthful, rich, honourable, a senator, a consul, happy in his wife, happy in his children," &c. yet this man was not void of melancholy, he had his share of sorrow. [929]Polycrates Samius, that flung his ring into the sea, because he would partic.i.p.ate of discontent with others, and had it miraculously restored to him again shortly after, by a fish taken as he angled, was not free from melancholy dispositions. No man can cure himself; the very G.o.ds had bitter pangs, and frequent pa.s.sions, as their own [930]poets put upon them. In general, [931]"as the heaven, so is our life, sometimes fair, sometimes overcast, tempestuous, and serene; as in a rose, flowers and p.r.i.c.kles; in the year itself, a temperate summer sometimes, a hard winter, a drought, and then again pleasant showers: so is our life intermixed with joys, hopes, fears, sorrows, calumnies: _Invicem cedunt dolor et voluptas_," there is a succession of pleasure and pain.

[932] ------"medio de fonte leporum Surgit amari aliquid, in ipsis floribus angat."

"Even in the midst of laughing there is sorrow," (as [933]Solomon holds): even in the midst of all our feasting and jollity, as [934]Austin infers in his _Com. on the 41st Psalm_, there is grief and discontent. _Inter delicias semper aliquid saevi nos strangulat_, for a pint of honey thou shalt here likely find a gallon of gall, for a dram of pleasure a pound of pain, for an inch of mirth an ell of moan; as ivy doth an oak, these miseries encompa.s.s our life. And it is most absurd and ridiculous for any mortal man to look for a perpetual tenure of happiness in his life. Nothing so prosperous and pleasant, but it hath [935]some bitterness in it, some complaining, some grudging; it is all [Greek: glukupikron], a mixed pa.s.sion, and like a chequer table black and white: men, families, cities, have their falls and wanes; now trines, s.e.xtiles, then quartiles and oppositions. We are not here as those angels, celestial powers and bodies, sun and moon, to finish our course without all offence, with such constancy, to continue for so many ages: but subject to infirmities, miseries, interrupted, tossed and tumbled up and down, carried about with every small blast, often molested and disquieted upon each slender occasion, [936]uncertain, brittle, and so is all that we trust unto. [937]

"And he that knows not this is not armed to endure it, is not fit to live in this world (as one condoles our time), he knows not the condition of it, where with a reciprocalty, pleasure and pain are still united, and succeed one another in a ring." _Exi e mundo_, get thee gone hence if thou canst not brook it; there is no way to avoid it, but to arm thyself with patience, with magnanimity, to [938]oppose thyself unto it, to suffer affliction as a good soldier of Christ; as [939]Paul adviseth constantly to bear it. But forasmuch as so few can embrace this good council of his, or use it aright, but rather as so many brute beasts give away to their pa.s.sion, voluntary subject and precipitate themselves into a labyrinth of cares, woes, miseries, and suffer their souls to be overcome by them, cannot arm themselves with that patience as they ought to do, it falleth out oftentimes that these dispositions become habits, and "many affects contemned" (as [940]Seneca notes) "make a disease. Even as one distillation, not yet grown to custom, makes a cough; but continual and inveterate causeth a consumption of the lungs;" so do these our melancholy provocations: and according as the humour itself is intended, or remitted in men, as their temperature of body, or rational soul is better able to make resistance; so are they more or less affected. For that which is but a flea-biting to one, causeth insufferable torment to another; and which one by his singular moderation, and well-composed carriage can happily overcome, a second is no whit able to sustain, but upon every small occasion of misconceived abuse, injury, grief, disgrace, loss, cross, humour, &c. (if solitary, or idle) yields so far to pa.s.sion, that his complexion is altered, his digestion hindered, his sleep gone, his spirits obscured, and his heart heavy, his hypochondries misaffected; wind, crudity, on a sudden overtake him, and he himself overcome with melancholy.

As it is with a man imprisoned for debt, if once in the gaol, every creditor will bring his action against him, and there likely hold him. If any discontent seize upon a patient, in an instant all other perturbations (for--_qua data porta ruunt_) will set upon him, and then like a lame dog or broken-winged goose he droops and pines away, and is brought at last to that ill habit or malady of melancholy itself. So that as the philosophers make [941]eight degrees of heat and cold, we may make eighty-eight of melancholy, as the parts affected are diversely seized with it, or have been plunged more or less into this infernal gulf, or waded deeper into it.

But all these melancholy fits, howsoever pleasing at first, or displeasing, violent and tyrannizing over those whom they seize on for the time; yet these fits I say, or men affected, are but improperly so called, because they continue not, but come and go, as by some objects they aye moved. This melancholy of which we are to treat, is a habit, _mosbus sonticus_, or _chronicus_, a chronic or continuate disease, a settled humour, as [942]

Aurelia.n.u.s and [943]others call it, not errant, but fixed; and as it was long increasing, so now being (pleasant, or painful) grown to an habit, it will hardly be removed.

SECT. I. MEMB. II.

SUBSECT. I.--_Digression of Anatomy_.

Before I proceed to define the disease of melancholy, what it is, or to discourse farther of it, I hold it not impertinent to make a brief digression of the anatomy of the body and faculties of the soul, for the better understanding of that which is to follow; because many hard words will often occur, as mirach, hypocondries, emerods, &c., imagination, reason, humours, spirits, vital, natural, animal, nerves, veins, arteries, chylus, pituita; which by the vulgar will not so easily be perceived, what they are, how cited, and to what end they serve. And besides, it may peradventure give occasion to some men to examine more accurately, search further into this most excellent subject, and thereupon with that royal [944]prophet to praise G.o.d, ("for a man is fearfully and wonderfully made, and curiously wrought") that have time and leisure enough, and are sufficiently informed in all other worldly businesses, as to make a good bargain, buy and sell, to keep and make choice of a fair hawk, hound, horse, &c. But for such matters as concern the knowledge of themselves, they are wholly ignorant and careless; they know not what this body and soul are, how combined, of what parts and faculties they consist, or how a man differs from a dog. And what can be more ignominious and filthy (as [945]Melancthon well inveighs) "than for a man not to know the structure and composition of his own body, especially since the knowledge of it tends so much to the preservation, of his health, and information of his manners?" To stir them up therefore to this study, to peruse those elaborate works of [946]Galen, Bauhines, Plater, Vesalius, Falopius, Laurentius, Remelinus, &c., which have written copiously in Latin; or that which some of our industrious countrymen have done in our mother tongue, not long since, as that translation of [947]Columbus and [948]

Microcosmographia, in thirteen books, I have made this brief digression.

Also because [949]Wecker, [950]Melancthon, [951]Fernelius, [952] Fuschius, and those tedious Tracts _de Anima_ (which have more compendiously handled and written of this matter,) are not at all times ready to be had, to give them some small taste, or notice of the rest, let this epitome suffice.

SUBSECT. II.--_Division of the Body, Humours, Spirits_.

Of the parts of the body there may be many divisions: the most approved is that of [953]Laurentius, out of Hippocrates: which is, into parts contained, or containing. Contained, are either humours or spirits.

_Humours_.] A humour is a liquid or fluent part of the body, comprehended in it, for the preservation of it; and is either innate or born with us, or advent.i.tious and acquisite. The radical or innate, is daily supplied by nourishment, which some call cambium, and make those secondary humours of ros and gluten to maintain it: or acquisite, to maintain these four first primary humours, coming and proceeding from the first concoction in the liver, by which means chylus is excluded. Some divide them into profitable and excrement.i.tious. But [954]Crato out of Hippocrates will have all four to be juice, and not excrements, without which no living creature can be sustained: which four, though they be comprehended in the ma.s.s of blood, yet they have their several affections, by which they are distinguished from one another, and from those advent.i.tious, peccant, or [955]diseased humours, as Melancthon calls them.

_Blood_.] Blood is a hot, sweet, temperate, red humour, prepared in the mesaraic veins, and made of the most temperate parts of the chylus in the liver, whose office is to nourish the whole body, to give it strength and colour, being dispersed by the veins through every part of it. And from it spirits are first begotten in the heart, which afterwards by the arteries are communicated to the other parts.

Pituita, or phlegm, is a cold and moist humour, begotten of the colder part of the chylus (or white juice coming out of the meat digested in the stomach,) in the liver; his office is to nourish and moisten the members of the body, which as the tongue are moved, that they be not over dry.

Choler, is hot and dry, bitter, begotten of the hotter parts of the chylus, and gathered to the gall: it helps the natural heat and senses, and serves to the expelling of excrements.

_Melancholy_.] Melancholy, cold and dry, thick, black, and sour, begotten of the more feculent part of nourishment, and purged from the spleen, is a bridle to the other two hot humours, blood and choler, preserving them in the blood, and nouris.h.i.+ng the bones. These four humours have some a.n.a.logy with the four elements, and to the four ages in man.

_Serum, Sweat, Tears_.] To these humours you may add serum, which is the matter of urine, and those excrement.i.tious humours of the third concoction, sweat and tears.

_Spirits_.] Spirit is a most subtle vapour, which is expressed from the blood, and the instrument of the soul, to perform all his actions; a common tie or medium between the body and the soul, as some will have it; or as [956]Paracelsus, a fourth soul of itself. Melancthon holds the fountain of those spirits to be the heart, begotten there; and afterward conveyed to the brain, they take another nature to them. Of these spirits there be three kinds, according to the three princ.i.p.al parts, brain, heart, liver; natural, vital, animal. The natural are begotten in the liver, and thence dispersed through the veins, to perform those natural actions. The vital spirits are made in the heart of the natural, which by the arteries are transported to all the other parts: if the spirits cease, then life ceaseth, as in a syncope or swooning. The animal spirits formed of the vital, brought up to the brain, and diffused by the nerves, to the subordinate members, give sense and motion to them all.

SUBSECT. III.--_Similar Parts_.

_Similar Parts_] Containing parts, by reason of their more solid substance, are either h.o.m.ogeneal or heterogeneal, similar or dissimilar; so Aristotle divides them, _lib. 1, cap. 1, de Hist. Animal._; Laurentius, _cap. 20, lib. 1._ Similar, or h.o.m.ogeneal, are such as, if they be divided, are still severed into parts of the same nature, as water into water. Of these some be spermatical, some fleshy or carnal. [957]Spermatical are such as are immediately begotten of the seed, which are bones, gristles, ligaments, membranes, nerves, arteries, veins, skins, fibres or strings, fat.

_Bones_.] The bones are dry and hard, begotten of the thickest of the seed, to strengthen and sustain other parts: some say there be 304, some 307, or 313 in man's body. They have no nerves in them, and are therefore without sense.

A gristle is a substance softer than bone, and harder than the rest, flexible, and serves to maintain the parts of motion.

Ligaments are they that tie the bones together, and other parts to the bones, with their subserving tendons: membranes' office is to cover the rest.
