Edgar Rice Burroughs: Tarzan of the Apes

Chapter 26: The Height of Civilization (continued)

Squeezing a drop of ink onto the glass, he spread it back and forth with the rubber roller until the entire surface of the glass was covered to his satisfaction with a very thin and uniform layer of ink.

"Place the four fingers of your right hand upon the glass, thus," he said to D'Arnot. "Now the thumb. That is right. Now place them in just the same position upon this card, here, no--a little to the right. We must leave room for the thumb and the fingers of the left hand. There, that's it. Now the same with the left."

"Come, Tarzan," cried D'Arnot, "let's see what your whorls look like."

Tarzan complied readily, asking many questions of the officer during the operation.

"Do fingerprints show racial characteristics?" he asked. "Could you determine, for example, solely from fingerprints whether the subject was Negro or Caucasian?"

"I think not," replied the officer.

"Could the finger prints of an ape be detected from those of a man?"

"Probably, because the ape's would be far simpler than those of the higher organism."

"But a cross between an ape and a man might show the characteristics of either progenitor?" continued Tarzan.

"Yes, I should think likely," responded the official; "but the science has not progressed sufficiently to render it exact enough in such matters. I should hate to trust its findings further than to differentiate between individuals. There it is absolute. No two people born into the world probably have ever had identical lines upon all their digits. It is very doubtful if any single fingerprint will ever be exactly duplicated by any finger other than the one which originally made it."

"Does the comparison require much time or labor?" asked D'Arnot.

"Ordinarily but a few moments, if the impressions are distinct."
