Signing Bonds and Stocks.
In the more important and complicated transactions in bank paper one bank may forward from the bank itself the finger print proofs of identity. 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 institution 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 documents, the danger in attempting frauds of this kind is increased.
The beauty of the finger print system is that there is absolutely no chance for error. The finger prints of the child of eighteen months will be the same as the finger prints of the man of eighty. No laceration, wound, or mutilation can disturb the essentials of the outline of the finger print. The only escape for the criminal is to cut off all of his fingers, and even then the toe prints would be as effective.
As to the physical necessities in registering finger prints, 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 is required. For removing the ink on the 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.

Objects to Having Finger Impressions Recorded.
In one of our prisons recently, a man who had just been sentenced was brought up, and while he made no opposition to being measured by the Bertillon system, he objected strongly to having his finger impressions recorded. This caused the identification expert to be suspicious, and he submitted a duplicate record to the Scotland Yard police, in London, with the result that the man was at once identified as a murderer who had escaped from a prison in England, and was taken back there. When confronted with the English record, the convict at once admitted his identity.
An express company lost a large sum of money which was being sent from one point to another in a sealed package. During transmission the seals were broken, the money abstracted and the package resealed with wax. At first the express company were absolutely unable to locate the thief, but later on it was discovered that in resealing the package, the thief had wet his finger and pressed it on the warm wax, leaving a distinct imprint. The finger impressions of all the agents through whose hands the package passed, were taken, with the result that the thief was easily identified, a confession obtained and the money recovered.
