Mr. Belin.

This was done under your direction?

Mr. Day.

I directed them to make it, and also paraffin casts or just of a piece of paraffin on the left side of the face to see if there were any nitrates there.

Mr. Belin.

On the left side or right side of the face?

Mr. Day.

Right side.

Mr. Belin.

Do you know what the results of the paraffin tests were?

Mr. Day.

The test on the face was negative.

Mr. Belin.

Had you ever done a paraffin test on a face before?

Mr. Day.

No; actually--had it not been for the particular type of case and this particular situation here we would not have at this time. It was just something that was done to actually keep from someone saying later on, "Why didn't you do it?"
Actually, in my experience there, shooting a rifle with a telescopic sight there would be no chance for nitrates to get way back or on the side of the face from a rifle.

Mr. Belin.

Well, the chamber, the nature of the chamber of the rifle, would that have anything to do with that?

Mr. Day.

Yes, sir.

Mr. Belin.

In what way?

Mr. Day.

A rifle such as that one we are talking about here from the sixth floor of the Texas School Book Depository, in my opinion, would not throw nitrates back to where a man's face was when he is looking through a telescopic sight.

Mr. Belin.

Well, when you ran these tests you had understood that the man, Oswald, had fired a pistol, too, hadn't he?

Mr. Day.

Yes, sir.

Mr. Belin.

Would you expect to have any positive tests from a pistol on the cheek?

Mr. Day.

I would expect more with a revolver with an open cylinder than I would from a rifle. Actually, for most practical purposes, I would not be surprised if there would be no nitrates from a man firing a rifle.

Mr. Belin.

What about on the hands?

Mr. Day.

Even on the hands. It is possible, but it is more likely with a revolver where you have a revolving cylinder and an opening between the cylinder and the actual barrel where the nitrates can come out.

Mr. Mccloy.

That was the type of pistol that was used to kill Tippit, wasn't it?

Mr. Day.

Yes, sir.

Mr. Mccloy.

Did the paraffin show up nitrate?

Mr. Day.

Yes, sir; nitrates were present on the cast made of Oswald's hands.

Mr. Belin.

Is there anything else, are there any other comments you have with regard to the paraffin test, sir?

Mr. Day.

No, sir.

Mr. Belin.

You are showing me your report of paraffin findings. Is this the same report that was sent into the FBI, if you know?

Mr. Day.

I think they were sent a report. This is the report submitted by the laboratory at Dallas who first processed this paraffin. Later on the FBI did come and want this paraffin, and it was turned over to them, also the can from which this was made. I don't know what purpose they wanted it for.

Mr. Belin.

I believe you mentioned that you took a measurement of the area in which the long paper bag was found to show how big an area that was with relation to the easternmost pair of windows on the east side of the building, and the on the south side of the building rather--and on the southeast corner juncture of the south wall to the east wall.
Mr. DAY, Yes, sir.

Mr. Belin.

All right. Handing you what has been marked as "Commission Exhibit 734"--you are using another exhibit there----

Mr. Day.

It is the same, it would be the same. I just had my measurements on there, was all.

Mr. Belin.

729, is this the one that you have here?
