Mr. Eisenberg.

Now, when we were talking before about the palmprint, and you said that it was on the right side you said it was on the ulnar portion of the palm?

Mr. Latona.

That is correct.

Mr. Eisenberg.

And that is looking at the palm itself?

Mr. Latona.

Looking at the palm itself.

Mr. Eisenberg.

Now, I would rather----

Mr. Latona.

That would still be the ulnar side when you look at the print.

Mr. Eisenberg.

Why don't we use ulnar and radial then when we refer to portions of fingerprints, ulnar referring to the little-finger side, and radial to the thumb side? So referring to the left index fingerprint now, that would correspond to the ulnar side of the left index finger of Lee Harvey Oswald?

Mr. Latona.

That is correct.

The Chairman.

Congressman Ford, I'm going to leave now to attend a session of the Court. If you will preside in my absence, Mr. Dulles will be here in a few moments, and. if you are obliged go leave for your work in the Congress, he will preside until I return.
(At this point, Mr. Dulles entered the hearing room and the Chairman left the hearing room.)

Mr. Eisenberg.

Mr. Latona, could you show us where on the paper bag, Exhibit 626, this left index finger was developed by you?

Mr. Latona.

The left index fingerprint was developed in the area which is indicated by this small red arrow.

Mr. Eisenberg.

Could you put a "B" on that arrow to which you are pointing?
Mr. Latona, did you make comparison charts of the known and latent or the inked and latent palmprints of Lee Harvey Oswald which you have been referring to as found on this paper bag, 626?

Mr. Latona.

Yes; I did.

Mr. Eisenberg.

Could you----

Mr. Dulles.

Shouldn't you change that question a little bit? I don't think you should say Lee Harvey Oswald at this point.

Mr. Eisenberg.

He has identified the print as being that of Lee Harvey Oswald.

Mr. Dulles.

Excuse me.

Mr. Eisenberg.

Mr. Latona, could you show us that chart and discuss with us some of the similar characteristics which you found in the inked and latent print which led you to the conclusion that they were identical?

Mr. Latona.

Yes. I have here what are referred to as two charted enlargements. One of the enlargements, which is marked "Inked Left Index Fingerprint. Lee Harvey Oswald" is approximately a 10-time enlargement of the fingerprint which appears on Exhibit 633A. The other enlargement, which is marked "Latent Fingerprint on Brown Homemade Paper Container," is approxi- mately a 10-time enlargement of the latent fingerprint which was developed on the brown wrapping paper indicated by the red arrow, "B."

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.
