Disputed Handwriting Part 7

With the ink thumb-print of the cas.h.i.+er of a bank placed on a bank draft over his signature and over the written amount of the draft, chemical papers and the dangers of "raising" or counterfeiting the draft would have no further consideration. The thumb-print of the secretary of the United States treasury, reproduced on the face of greenback, silver certificate and bank note of any series would discourage counterfeiting as nothing else ever has done.

But this thumb-print possibility in commercial papers has its greatest future in the positive identification which either thumb or finger print carries with it. Criminologists all over the world have satisfied themselves of the absolute accuracy of the fingerprint identification.

At the present time traveling salesmen, who spend much money and who wish to carry as little as possible of cash with them, have an organized system by which their bankable paper may be cashed at hotels and business houses over the country. But with the thumb-print in use, as it might be, such an organization would be unnecessary.

As between bank and bank, this use of the fingerprint in bank papers of large face value is especially applicable. A draft for $100,000 or $1,000,000 may be worth more consideration of the banks concerned than the penmans.h.i.+p of signer and countersigner of the paper.

In the s.h.i.+pment of currency where there may be question of either honesty or correctness in the persons sealing the package, a thumb-print in wax will determine absolutely whether the wax has been unbroken in transit, as well as establis.h.i.+ng the ident.i.ty of the person putting on the first seal. As to the protective value of such a thumb-seal, a case has been cited in which train robbers, discovering a chance seal of the kind in wax of such a package, left that package untouched when the express safe had been blown open; it was too suggestive of danger to be risked.

In the ordinary usage of the thumb-print on bankable paper the city bank having its country correspondents everywhere often is called upon to cash a draft drawn by the country bank in favor of that bank's customer, who may be a stranger in the city. The city bank desires to accommodate the country correspondent as a first proposition. The unidentified bearer of the draft in the city may have no acquaintance able to identify him. If he presents the draft at the windows of the big bank, hoping to satisfy the inst.i.tution, and is turned away, he feels hurt. By the thumb-print method he might have his money in a moment.

In the first place, even the signature of the cas.h.i.+er of the country bank will be enough to satisfy its correspondent in the city of the genuineness of the draft. Before the country purchaser of the draft has left the bank issuing the paper he will be required to make the ink thumb-print in a s.p.a.ce for that purpose. Without this imprint the draft will have no value. If the system should be in use, the cas.h.i.+er signing the draft will not affix his signature to the paper until this imprint has been made in his presence.

Then, with his attested finger-print on the face of the draft, the stranger in the city may go to the city bank, appearing at the window of the newest teller, if need be. This teller will have at hand his inked pad, faced with a sheet of smooth tin. He never may have seen the customer before. He never may see him again. But under the magnifying influences of an ordinary reading gla.s.s he may know past the possibility of doubt that in the hands of the proper person named in the draft the imprint which is made before him has been made by the first purchaser of the draft.

In the more important and complicated transactions in bank paper one bank may forward from the bank itself the finger-print proofs of ident.i.ty. The whole field of such necessities is open to adapted uses of the method. Notes given by one bank to another in high figures may be protected in every way by these imprints. Stock issues and inst.i.tution bonds would be worthy of the thumb-print precautions, as would be every other form of paper which might tempt either the forger or the counterfeiter. In any case where the authenticity of the paper might be questioned, the finger-print would serve as absolute guarantee. In stenographic correspondence, where there might be inducements to write unauthorized letters on the part of some person with wrong intent, the imprint of finger or thumb would make the possibility of fraud too remote for fears. For, in addition to the security of signatures in real doc.u.ments, the danger in attempting frauds of this kind is increased.

As to the physical necessaries in registering fingerprints, they are simple and inexpensive. A block of wood faced with smooth tin or zinc the size of an octavo volume, a small ink roller, and a tube of black ink are all that are required. For removing the ink on thumb or finger a towel and alcohol cleanser are sufficient. A tip impression or a "rolled" finger signature may be used. Only a few seconds are required for the operation.

In giving big checks merchants and bankers would be protected by the thumb-print system. A merchant could place the print of his right index finger to the left of his signature on a check. The bank would have a print, together with the merchant's signature on file. Only a few seconds would be necessary to convince the paying teller as to its genuineness. The merchant, also, if necessary, could place a light print of the index finger over the amount of the check where written in figures. Any attempt to erase the figures would destroy the finger-print. If the figures were raised, the one doing so would be unable to place a finger-print in the same s.p.a.ce that would correspond with the one at the bottom of the check beside the signature, and the raising of the check would immediately be discovered in the bank where the check was presented.

The finger-prints could be used also in all manner of doc.u.ments filed for record, such as deeds to lands, mortgages, leases, and the like.

Railroads could use it to prevent men once employed and discharged for incompetency obtaining employment on another division, thus doing away with inspectors. Each new employee's finger-prints could be kept in a central office and cla.s.sified. Any man attempting to obtain employment again with the same railway, who had once been discharged for cause, would immediately be detected, and a high standard of personnel thus obtained.

Congress recently pa.s.sed a law whereby the Bureau of Immigration is permitted to tax each immigrant four dollars; this sum to be used in detecting foreign criminals who come to this country; also to aid in ascertaining whether foreigners who come here commit crimes and get into prisons. If such are found they are to be deported. By the finger-print system the prints of each foreigner could be taken at all ports of entry. These could be kept on file in Was.h.i.+ngton, and from time to time compared with those sent to the Bureau of Criminal Registry in the Department of Justice building. Any foreigner located in a prison could be ascertained, and upon the termination of his sentence taken to some port and placed on board s.h.i.+p.

It has been demonstrated by experts that the ridges of finger tips do not change from birth until death and decomposition. Scars made on the finger tips remain throughout life, and are valuable for identification purposes. Criminals try to evade identification by the system by burning the tips of their digits with acid; but these are cla.s.sified under the head of disfigured fingers, and a lawbreaker cannot escape detection. Even the removal of two, three, or four fingers or an entire hand does not prevent a criminal being traced if his prints were taken before he lost the five digits. In the case of one hand being amputated, the missing fingers are cla.s.sified as they appear on the other hand. If a search fails to locate the person, then the missing fingers are cla.s.sified first as whorls and then as loops, search being made after each cla.s.sification. In this manner the search may be a little more tedious than it would be if all the fingers were there, but in time he would be identified.

The Department of Justice thinks so well of the system that it has recently established in Was.h.i.+ngton a Bureau of Criminal Registry. There the finger-print sheets, and for the time being Bertillon cards, of all criminals who have been convicted of violating federal laws are to be kept. The prints and Bertillon measurements of new arrivals at government prisons and jails will also be sent there for cla.s.sification, none of this work being done at prisons as heretofore. The men held in federal jails, charged with crimes, are also to have their finger-prints taken, and these sent to the central bureau. If the expert in charge of this bureau ascertains that a man indicted for crime has served a previous term in prison, this fact is to be communicated to the United States judge and district attorney, and if convicted the criminal is to be given the full limit of sentence.

Although the system of identification by fingerprints has been in use in Europe for a number of years, it is not a European invention. As a matter of fact, it is one of those cherished western inst.i.tutions that the Chinese have calmly claimed for their own, and those who doubt this may be convinced by actual history showing it to have been employed in the police courts of British India for a generation or so back. Just who was responsible for its adoption there is not certain, but Sir John Herschel, at one time connected with the India civil service, is usually mentioned in this regard. The British police experienced a great deal of trouble in keeping track of even the most notorious native criminals and it was a great deal more difficult to arrest a first offender, for the reason that all the natives looked so much alike and were such apt liars.

Ordinary methods, even the Bertillon system, were fruitless and finally the finger-print scheme was tried. It worked like a charm.

Where more arrests had been the exception, they now became the rule and the power of the law began to merit respect. In case after case the police were enabled to track the crime solely by the chance print of a man's finger or thumb on an odd piece of paper, on the dusty lintel of a doorway or a dirty window pane. Some of the stories told of their accomplishments in this line rival the most thrilling detective stories.

In one case, that of the murder of a manager of a tea garden on the Bhupal frontier, half a dozen or more persons were at first suspected, among them the real murderer, who was, however, later regarded as innocent because he was supposed to have been away from the district at the time the crime was committed. Investigations and questionings did no good, and at last the local inspector decided to take the thumb-prints of all concerned and refer them to the central office of the province. After the records had been searched a messenger came with orders to arrest the discharged servant of the manager who had been first suspected and then exonerated, for his finger-prints tallied exactly with those of a bad character just discharged from prison. He was later convicted of burglary by a court of appeal, to which the case was carried, the court refusing to condemn a man for murder on such slight basis when the actual crime had not been observed.

At the present time in India the papers taken in the civil-service examinations must be certified to by the thumb-print of the compet.i.tor and wills must likewise be sealed in the same way, and all checks and drafts must be certified by a thumb-print in addition to a signature.

In India, also deeds of transfer, and records of sale of land in connection with illiterate natives are executed by the impression of a thumb-mark instead of an "X, his mark"; and recently this very superior system of signature has been applied to all kinds of transactions with the natives, such as post-office savings banks, pension certificates, mortgages, etc.

The success the plan met with in India led to its trial and speedy adoption by the French and English police. In Paris it is used as an adjunct to the measurement system of M. Bertillon, but at Scotland Yard the Bertillon system has been entirely done away with and full reliance is had on the prints. M. Bertillon claims to have 500,000 prints in his collection, although this is said by the authorities to be an exaggeration, and Inspector McNaughton of the convict supervision office has at least 100,000 criminals' hands catalogued in his office.

Finger marks do not change in any way through life, and any injury only temporarily affects the pattern. The pattern becomes larger as the youth develops into a man, but the arrangement of the lines remains absolutely the same.

Thumb-marks may be generally cla.s.sified as loops, arches and ovals, or whorls; the ovals irresistibly remind one of whirlpools as well as the volutions of sh.e.l.ls, while the majority of loops or arches resemble in their convolutions the rapid movement of rus.h.i.+ng water.

Thumb-print identifications have been extended to commercial uses by the postal savings bank on the Philippines at Manila. This bank has recently issued a series of stamp deposit cards, on which are s.p.a.ces for stamps of different values to be affixed. When the depositor has stamps to the value of 1 peso (50 cents) on the card it is exchanged at the bank for a deposit book, showing the amount to his credit.

Opposite the lines for the owner's signature and address is a square ruled off for the reception of his thumb-print, so that even if illiterate, depositors may readily be identified.

If any one wishes to get a thumb-print impression without the suspect's knowledge, simply hand him a piece of paper, asking him to identify it or examine it for one reason or another, afterwards sprinkling some special black powder over it which brings out the impressions as clear as life. Another sort of white powder is used for bringing out impressions on gla.s.sware.

Once the impression is secured, the fingers are cla.s.sified according to a regular plan. The lines on them are divided into loops, whorls, arches, and composites, the latter cla.s.s made up of a collection of the first three. Each pair of fingers as the index, little and ring fingers has a special valuation which is used to identify them and facilitate cla.s.sification. One pair will be cla.s.sified according to the number of little ridges between the delta, or point where all bifurcate, and the outer ring. If there are more than nine on one finger, it is cla.s.sed as an over-nine.

It is seldom that two similar fingers are alike and the other finger usually would be an under-nine finger, say six. So there is the first pair cla.s.sified thus, 9-6. The next two fingers may have rotary lines and are merely cla.s.sified as R, the next two may not have many lines at all that will count, so are marked 0, while perhaps the last pair is unmatched, a point being allowed to one and nothing to the other.

Thumb or finger-prints are absolutely serviceable and certain in the detection of crime or in establis.h.i.+ng a person's ident.i.ty.

That this system may be most effectively employed as an adjunct to the rogue's gallery for fixing the ident.i.ty of criminals there can be no doubt, since, from various experiments made it has been demonstrated that impressions made from the dermal furrows of the thumb or finger of no two persons can be sufficiently identical, when inspected under a microscope, to be mistaken one for the other; and that it is a powerful agency for the detection of criminals.

Very often, on the scene of a crime, finger marks are found on glossy surfaces (bottles, gla.s.ses, window panes, door plates, painted and varnished walls, etc.). By a comparison of such impressions, photographed by a special process, it is easy either to discover the maker of the finger marks observed at the scene of the crime, or to establish the innocence of a suspected person whose digital impressions have nothing in common with those marks.

DETECTING FORGERY WITH THE MICROSCOPE

Determining Questionable Signatures By the Aid of a Microscope--A Magnifying Gla.s.s Not Powerful Enough--Character of Ink Easily Told--The Microscope and a Knowledge of Its Use--Experience and Education of an Examiner of Great a.s.sistance--An Expert's Opinion--The Use of the Microscope Recommended--Ill.u.s.trating a Method of Forgery--What a Microscopic Examination Reveals--How to Examine Forged Handwriting with a Microscope--Experts and a Jury--What the Best Authorities Recommend.

In all examinations of questioned signatures to determine the individual habit of the writer the use of the compound microscope is a necessity to obtain the best field for study and a.n.a.lysis for the reason that the most important details are often so minute that they cannot be seen with the naked eye in sufficient size to determine their individual character and accuracy. A magnifying gla.s.s has but a limited field in this cla.s.s of work, for it is not easily held in position steadily for continued observation and study, besides it has not the requisite power for the work. The lower powers of the compound microscope are but available for the examination of signatures for the reason that when the higher powers are used but little of the signature is in the field of vision, although the power of the lens may be increased when some particular point or feature in the writing requires greater enlargement for more perfect definition. The higher powers of the microscope are sometimes used to ascertain the character of inks with which the writing is done, and also to determine the character of the paper on which a signature is written, which at times becomes important. For all practical uses of the microscope in the examination of signatures the range of object enlargement occurring between a three-inch and an inch objective will be found to answer the purpose, as the various powers of the lenses become important in making the a.n.a.lysis.

While it is a fact that the microscope and a knowledge of its uses is of the greatest importance in ascertaining the character of the signatures, when the question of their being forged or genuine is the object of the examination, it does not follow that because a person is learned in the use of the microscope in other fields of research that he is therefore qualified to become an expert in handwriting. A peculiar education made practically applicable by experience in this latter field of study is absolutely necessary to determine with accuracy what the microscope reveals, and its importance to give value to any conclusions reached by its use. The connection of effect with cause, and the determination of the latter as a matter of individualism cannot be accomplished merely from what is seen under the microscope.

The examiner must by experience and education be fitted to ascertain from personal characteristics manifested in the writing of a signature necessitated their appearance as a matter of individuality.

From one of the best-known European experts on handwriting and who has figured conspicuously in important cases some interesting facts relative to this subject recently were learned. To the question, "What is the primary requisite for a conscientious opinion on the genuineness of any submitted handwriting?" this expert unhesitatingly replied, "An utter and entire absence of either feeling or prejudice.

In other words, one should be perfectly dispa.s.sionate when engaged in such a work and use a first-cla.s.s compound microscope."

To make his a.n.a.lysis the expert uses a microscope of great power, and by a strict and close attention to the subject-matter he can determine the exact means or methods employed in making the individual letters and the formation of the words and also the several inks that were used. Handwriting as defined by this expert is a mechanical operation pure and simple. Its general excellence or the reverse is largely dependent on the education which the hand has received. When a man sits down to write he mechanically reproduces on paper what is in his mind, and this may be said to be his natural handwriting. Should he stop to think even for a moment, not of what he is transferring to the paper but of the writing itself, he instantly ceases to write his natural hand, the transcription becoming only a copy or drawing from memory.

In the opinion of the expert, emphatically expressed, a person never writes twice exactly alike. This is stated to be the point around which all his subsequent developments revolve when examining a ma.n.u.script. Let several examples of the natural handwriting of an individual be compared. It is true that there will be a general similarity, but, as has been a.s.serted, when placed in juxtaposition or subjected to a careful comparison under a microscope no two words or letters will be found to be alike. Thus it is not the similarity between two pieces of writing that would arouse suspicion with some experts, but rather the natural dissimilarity. Based on this point such experts occupy a distinct position by themselves, since other experts take what is called the positive side. With the first-named cla.s.s, however, handwriting is a science of negatives. A good microscope will always be found a good detective in determining the genuineness of handwriting.

By way of ill.u.s.trating one method of forgery interesting material which had played an important part in a court case was carefully examined. It consisted of five or six graded photographic enlargements of the duplicate signature which were carefully examined with the aid of a microscope. The original had been made by an elderly person and the forger had used the tracing process. To the naked eye it appeared to be a capital copy; in fact, it seemed to bear every semblance of being genuine. In the first enlargement of several diameters certain inaccuracies of tracing could be discerned, only, however, after attention had been called to them by an expert. In the next enlargement these same errors were more apparent, and so on through the series. The largest photograph was magnified several hundred diameters greater than the original and stretched across quite an area of paper. From an examination of this largest one with a microscope it was evident that the forger first had traced his copy with pencil, afterward going over it with ink, but so irregularly had his pen followed the pencil lines that in certain portions of this enlargement there was room for a man's fist between the first tracing and its inky covering.

In trying to detect forged handwriting every letter of the alphabet, wherever written, may be examined with a microscope for the following characteristics: Size, shading, position relative to the horizontal line, inclination relative to the vertical line, sharpness of the curves and angles, proportion and relative position of the different parts, and elaboration or extension of the extremities. In scarcely one of these particulars can a man make two letters so much alike that they cannot be distinguished by microscopical examination.

Although a great deal can be determined in a general way by close observation with the naked eye, it is always best to employ some magnifying power--usually an ordinary hand lens or pocket magnifier will suffice--but the writer has found it better to use a microscope objective of low power (four or five diameters), which is provided with an easily slipping sleeve, terminating in a diaphragm which cuts out the light entering the outside rim of the lens. This sleeve may be pushed out for one or two centimeters, and the particular spot under examination isolated from the adjacent parts without undue magnification. It is one of the popular fallacies that a high magnifying power is desirable in all cases of difficulty, but usually the reverse is the case in questions of handwriting.

Experts have sometimes impressed the jury with the fact that they had employed on some thick and opaque doc.u.ment, powers of several hundred diameters without the lately applied illumination from the side, reflected by a gla.s.s plate, introduced obliquely into the tube of the microscope. Without such aid no microscopist need be told that the light would be wanting to illuminate the field under these circ.u.mstances. The best authorities prescribe a magnifying power of not more than ten diameters for ordinary observation. For special purposes higher powers are sometimes useful. An ocular examination of the ink in the various parts of a written paper, doc.u.ment or instrument of any kind will generally decide whether it is the same.
