Mr. Cadigan. I had it made.
Mr. Eisenberg. Mr. Chairman, may I have it in evidence?
Mr. Dulles. Admitted.
Mr. Cadigan. I would like to point out this is only one phase of the examination and this is a black-and-white photograph. In your examination under the microscope you are looking at the surface and memorizing everything about that surface your mind can retain by putting the two pieces of paper together and studying them back and forth. I don't wish to imply that that photograph represents all I can see in a microscope, because it doesn't.
Mr. Eisenberg. We understand that. May I have this, Mr. Reporter, marked as 678.
(Commission Exhibit No. 678 was marked, and received in evidence.)
Mr. Dulles. That has already been admitted.
Mr. Eisenberg. Yes. Now, what is the magnification in this Exhibit 678?
Mr. Cadigan. It is about 50 times enlarged.
Mr. Eisenberg. And had you treated the paper chemically before you made this photograph?
