Mr. CADIGAN. Yes; the width of the tape on the paper sack, Exhibit 142, I measured at 3 inches, and the width of the manila tape on Exhibit 677 obtained the night of November 22, I measured as 2.975. There is twenty-five one-thousandths of an inch difference. Mr. EISENBERG. Would that lead you to believe that they couldn't have come from the same roll? Mr. CADIGAN. No; certainly not. Mr. EISENBERG. Not enough of a variation to lead to that conclusion? Mr. CADIGAN. That is correct. Mr. EISENBERG. How wide do these rolls come in your experience, in what widths do they come? Mr. CADIGAN. Normally they are supplied in, I believe, 1-, 1-1/2-, 2-, 2-1/2-, and 3-inch widths. Mr. EISENBERG. So this was basically of a 3-inch width variety out of several possible alternatives? Mr. CADIGAN. Yes. Mr. EISENBERG. Is there any other information you would like to give us or any other testimony you would like to give us on the subject of the origin of the paper in the 142 bag? Mr. CADIGAN. Well, possibly the comparisons made of paper samples from Jaggars Chiles-Stovall and from the William B. Riley Co. Mr. EISENBERG. These are, you have mentioned two companies at which Oswald was employed at one time? Mr. CADIGAN. Yes. Mr. EISENBERG. You obtained paper from these companies, did you? Mr. CADIGAN. Yes, sir. Mr. EISENBERG. And you matched them to see if they matched--you tested them to see if they matched the paper in the bag 142, is that correct? Mr. CADIGAN. Yes; that is correct. Mr. EISENBERG. And your conclusion was what? Mr. CADIGAN. That they were different. Mr. EISENBERG. Yes. Anything else? Mr. CADIGAN. That is about it. Mr. EISENBERG. Mr. Chairman---- Mr. DULLES. Mr. Murray, do you have any questions? Mr. MURRAY. I don't believe I have, Mr. Commissioner, but I would like to mention this off the record, if I may. (Discussion off the record.) Mr. EISENBERG. We have now the ultraviolet machine set up. Could you just show us the difference in fluorescence? Mr. CADIGAN. Yes. Mr. EISENBERG. Can you explain what you have set up here, Mr. Cadigan? Mr. CADIGAN. This is a portable ultraviolet viewer I used to examine the papers and I think probably what is most noticeable is in the manila tapes. The tape on the right is the sample secured November 22. The tape at the top is from the bag 142, and then the one in the, you might say, lower left, toward the bottom, is the tape that was secured December 1. Mr. EISENBERG. You are referring to positions in the bottom of the ultraviolet machine? Mr. CADIGAN. Yes; relative position. Mr. DULLES. The one at the left is the one taken from the paper sack, isn't it? Mr. CADIGAN. Top left; yes; that would be from 142. Mr. DULLES. 142, and the other is---- Mr. CADIGAN. The one on the right is 677. Mr. DULLES. What am I supposed to see? Mr. CADIGAN. A difference in the appearance, difference in color. Mr. DULLES. What do you mean? I see the violet and I see the white.
