Mr. Eisenberg. Did you also break down the papers to test them, to determine the morphology of the fiber?

Mr. Cadigan. Yes. Subsequently, I ran a fiber analysis of the paper, the known paper sample from the Texas School Book Depository, Commission Exhibit 677, and the paper bag, Commission Exhibit 142, and on the same day I had our spectrographic section run a spectrographic test on these same papers.

Mr. Dulles. Do I understand correctly, though, you have testified that a sample taken 10 days later was different—or approximately 10 days later?

Mr. Cadigan. Yes.

Mr. Eisenberg. Approximately 10 days.

Mr. Cadigan. Yes; this was a sample taken December 1. I could tell that it was different from this sample, 677, taken on the day of the assassination, and different from the bag, Exhibit 142.

Mr. Dulles. Do you happen to know whether another roll was put in the machine between the 22d and the 1st of December?

Mr. Cadigan. May we go off the record?

(Discussion off the record.)

Mr. Eisenberg. On the record.
