Mr. Eisenberg.

Or some 9 or 10 days after the assassination?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

Was the paper obtained from the same source?

Mr. Cadigan.

Yes; from the same room.

Mr. Eisenberg.

The same room.
Did you examine this paper to see how it compared---that is, the paper in the replica bag, which has already been admitted as Commission Exhibit 364---to see how it compared with the paper in the bag found on the sixth floor of the TSBD, which is Commission's Exhibit 142?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

What was your conclusion?

Mr. Cadigan.

That they were different in color, visual color, felting--that is, the pattern that you see through transmitted light, and they were different under ultraviolet light.

Mr. Eisenberg.

So that these two papers, which were obtained within 9 or 10 days from the same source, could be distinguished by you?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

Have you brought an ultraviolet light source with you?

Mr. Cadigan.

Yes.

Mr. Eisenberg.

Could you show the Commission the difference between the three papers?
(Discussion off the record.)

Mr. Eisenberg.

Now, we have been unable to find a plug for this ultraviolet machine, so we will temporarily or perhaps permanently bypass this examination. But did you find that two of the papers look the same under the ultraviolet and a third looked different when you examined it under ultraviolet?

Mr. Cadigan.

Yes; that is correct.

Mr. Eisenberg.

Which two were the identical and which was the different one?

Mr. Cadigan.

Well---Commission Exhibit 142 and Commission Exhibit 677--I observed them to have the same appearance under ultraviolet light, and that appearance was different from Commission Exhibit 364.

Mr. Dulles.

Can you identify these three exhibits, because otherwise I think it will be very difficult to get into the record.

Mr. Eisenberg.

Yes, sir; 142 being the bag found on the sixth floor of the TSBD, 677 being the sample obtained that day from the shipping room in the Texas School Depository, and 364 being a replica made some ten days later out of paper obtained some 10 days later.
Did that complete your examination of the gross or physical characteristics, as opposed to the microscopic characteristics?

Mr. Cadigan.

Yes; that in essence was the extent of the examination I made at that time.

Mr. Eisenberg.

Did you go on to examine for microscopic characteristics?

Mr. Cadigan.

Yes; I believe I mentioned that at the time I had examined these papers under the microscope.

Mr. Eisenberg.

You mentioned that at the time?

Mr. Cadigan.

Yes; earlier this morning.

Mr. Eisenberg.

Yes.
Could you tell us what the results were of your examination under the microscope?

Mr. Cadigan.

Again, I found that the paper sack found on the sixth floor, Commission Exhibit 142, and the sample. secured 11-22, Commission Exhibit 677, had the same observable characteristics both under the microscope and all the visual tests that I could conduct.

Mr. Eisenberg.

Could you go into detail as to what you did see under the microscope?

Mr. Cadigan.

Well, I think perhaps this photograph, I have an enlarged photograph, one side being the----

Mr. Dulles.

Which side is that?

Mr. Eisenberg.

One side marked K-2, and the other Q-10?

Mr. Cadigan.

Yes; K-2 corresponds to the known paper sample 677.

Mr. Eisenberg.

Obtained from the TSBD?
