Mr. Eisenberg.

Now, Mr. Latona, what known sample of Lee Harvey Oswald's prints, finger and palm, did you use in making this identification?

Mr. Latona.

The known samples I used were the ones forwarded by our office at Dallas, the Dallas office.

Mr. Eisenberg.

Do you have those with you?

Mr. Latona.

I do.
Mr. EISENBERG. Mr. Latona, you have handled me three cards, one of which appears to be a standard fingerprint card, and the other two of which appear to be prints of the palms of an individual. All these cards are marked "Lee Harvey Oswald."
Are these the cards which you received from your Dallas office which you just described as being the prints of Lee Harvey Oswald?

Mr. Latona.

They are.

Mr. Eisenberg.

Mr. Chairman, I would like these admitted into evidence as 627, 628, and 629. I would like the standard fingerprint card, 10-print card, admitted as 627.

The Chairman.

It will be admitted.
(The item referred to was marked Commission Exhibit No. 627 and received in evidence.)

Mr. Eisenberg.

I would like the card which is--which appears to be the left palm admitted as 628.

The Chairman.

It will be admitted.
(The item referred to was marked Commission Exhibit No. 628 and received in evidence.)

Mr. Eisenberg.

I would like the card which is. the right pall admitted as 629.

The Chairman.

That may be admitted.
(The item referred to was marked Commission Exhibit No. 629 and received in evidence.)

Mr. Latona.

May I ask a question, please? Would it be possible to accept copies instead of the originals?

The Chairman.

They are identical?

Mr. Latona.

These are true and faithful reproductions of the originals which Mr. Eisenberg has.

The Chairman.

The originals, then, may be withdrawn, and the copies substituted for them.

Mr. Eisenberg.

Shall I mark those 627, 628, and 629 in the same manner as the originals?

The Chairman.

Exactly.

Mr. Eisenberg.

Mr. Latona, do you know how the known samples we have Just marked 627, 628, and 629 were obtained?

Mr. Latona.

How they were obtained?

Mr. Eisenberg.

Yes. Can you tell the process used in obtaining them?

Mr. Latona.

You mean in recording the impressions?

Mr. Eisenberg.

Yes, sir.

Mr. Latona.

Fingerprints are recorded by the use of a printer's ink, heavy black ink, which is first placed on a smooth surface, such as glass or metal, and it is rolled out in a smooth, even film. Then the subject's fingers are brought in contact with the plate by a rolling process, rolling the finger from one complete side to the other complete side, in order to coat the finger with

an even film of this heavy ink. Then the finger. is brought in contact with a standard fingerprint card and the finger again is rolled from one complete side to the opposite side in order to record in complete detail all of the ridge formation which occurs on the tip of the finger, or the first joint, which is under the nail.

Mr. Eisenberg.

Did you received a second submission of known prints?

Mr. Latona.

Yes; we did.

Mr. Eisenberg.

When did you receive those?

Mr. Latona.

Those were received in the identification division on November 29, 1963.

Mr. Eisenberg.

Did this include two palls, or was this simply----

Mr. Latona.

No; it did not. It was simply a fingerprint card.
