Mr. Eisenberg. Have you testified on that subject in court?
Mr. Cadigan. Yes, sir.
Mr. Eisenberg. Many times?
Mr. Cadigan. I won't say many, no; because most of the testimony I have given in court relates to other phases of the work. Strictly on paper, I would say not more than two or three times.
Mr. Eisenberg. But you have made more than two or three examinations of paper?
Mr. Cadigan. Oh, yes; far more.
Mr. Dulles. Running into the hundreds and thousands?
Mr. Cadigan. Yes, sir.
Mr. Eisenberg. Mr. Chairman, may I have this witness admitted as an expert witness?
Mr. Dulles. He shall be admitted as an expert on this subject.
