Mr. Eisenberg. May I have this admitted, Mr. Chairman?
Mr. Dulles. That may be admitted.
Mr. Eisenberg. That will be No. 677.
Mr. Dulles. 677 may be admitted.
(Commission Exhibit No. 677 was marked, and received in evidence.)
Mr. Eisenberg. Did you find out from precisely what portion of the Texas School Book Depository Building this was obtained, Mr. Cadigan?
Mr. Cadigan. Yes; this comes from the first floor, main floor of the Texas School Book Depository, referred to as the shipping room, the whole floor.
Mr. Eisenberg. Now, did you—who supplied you with this sample, this Exhibit 677?
Mr. Cadigan. This exhibit was brought to the laboratory by Special Agent Drain of our Dallas office, who brought all of this evidence in for examination.
