Mr. Eisenberg.

You have a chart here "Racial Determination of Hairs," and no subcaption, is that right?

Mr. Dulles.

You haven't asked for this other to be admitted, have you?

Mr. Eisenberg.

No; I will ask after he has finished with it.

Mr. Stombaugh.

Occasionally we will run into situations in hairs, where we cannot determine with any certainty whether or not the hairs are of the Caucasian or Negroid or Mongoloid race, by examining it longitudinally, and we have to make a cross- section of the hair. If we make a cross-section of the hair it is the same as taking a banana and cutting off a very thin slice of the banana and placing it under a microscope and examining it. We find in the Caucasian race the hairs are oval in shape. In the Negroid race the hairs are fiat, and have a flattened appearance, and in the Mongoloid race they are perfectly round. This is another characteristic which we use in determining the racial origin of hair.

Mr. Eisenberg.

May I have this chart admitted as 670?

Mr. Dulles.

Yes.
(Commission Exhibit No. 670 was marked, and received in evidence.)

Mr. Eisenberg.

Was it definitely established in your mind as a result of the various characteristics you have explained that the hairs found in the blanket were Caucasian hairs?

Mr. Stombaugh.

Yes, sir; they were all Caucasian hairs.

Mr. Eisenberg.

Did you examine those hairs and compare them with any known samples to determine whether they might have come from any specific individual?

Mr. Stombaugh.

Yes; I did.

Mr. Eisenberg.

What was your conclusion on that score?

Mr. Stombaugh.

I examined the hairs found on the blanket and determined that most of them were limb and pubic hairs. In other words, they originated either from the leg or the arm or from the pubic area. I found several head hairs on the blanket also.
These hairs I compared with known hair samples from Lee Harvey Oswald. I found several of the limb hairs from the blanket and several of the pubic hairs from the blanket matched in all observable microscopic characteristics, and concluded these hairs could have come from Oswald.

Mr. Eisenberg.

Where did you get the known sample, Mr. Stombaugh, of Lee Oswald's hair?

Mr. Stombaugh.

These were obtained and were sent to the laboratory by the FBI office in Dallas.
I do not know whether the agent in Dallas personally took the samples or had a member of the Dallas Police Department take the samples.

Mr. Eisenberg.

Were these hairs taken from one area or were they a representative sample?

Mr. Stombaugh.

It was a fairly good representative sample.

Mr. Eisenberg.

Could you review the microscopic characteristics which led you to your conclusion, Mr. Stombaugh?

Mr. Stombaugh.

This chart contains a photomicrograph of Oswald's pubic hairs. This is just a very small area taken of a glass microscope slide containing the hairs. There were numerous other hairs. The photograph on. the right shows one of the hairs I removed from the blanket, and one of the hairs from Oswald, showing, generally, the match.

Mr. Eisenberg.

Now, did you take these photographs on the left and right side yourself?

Mr. Stombaugh.

Yes; I did.

Mr. Eisenberg.

This chart is captioned on the left "Photomicrograph of Oswald's Pubic Hairs" and on the right "Hair from the Blanket" and "Hair from Oswald"?

Mr. Stombaugh.

Yes, sir.

Mr. Eisenberg.

May I have it admitted?
(The item referred to was marked as Commission Exhibit No. 672, and received into evidence.)

Mr. Dulles.

May I ask a question? The one on the right seems darker than the one on the left, the hair itself.

Mr. Stombaugh.

This one and this one?
