Mr. Eisenberg. And that also corresponds to the photograph you gave us, which is now Exhibit 633?
Mr. Latona. That's correct.
Representative Ford. And the arrow, "B," is on Exhibit 626?
Mr. Latona. That's correct. Now, in making a comparison of prints to determine whether or not they were made by the same finger, an examination is made first of all of the latent print.
An examination is made to see if there are in the latent print any points or characteristics which are unique to the person making the determination. In other words, in looking at the latent print, for example, this point, which is marked "1," is a ridge. The black lines are what we term ridges. They were made by the ridge formations on the fingers. That is, when the finger came in contact with the brown paper bag, it left an outline in these black lines on the brown paper bag.
Now, in looking at the latent print in the enlargement you notice there is one black line that appears to go upward and stop at the point which has been indicated as point No. 1.
Mr. Eisenberg. Mr. Latona, may I interrupt you there for a second.
Mr. Chairman, I would like to introduce this chart, this comparison chart, as an exhibit.
Representative Ford. It may be admitted.
Mr. Eisenberg. That will be 634.
