Mr. Specter. Have those particles been identified during the course of your prior testimony?
Mr. Frazier. No, sir; they have not?
Mr. Specter. Will you produce them at this time then, please? May we assign to this group of particles Commission Exhibit No. 840?
Mr. Dulles. These have not been discussed before, have they?
Mr. Specter. They have not.
Mr. Dulles. It shall be admitted as Commission Exhibit No. 840.
(Commission Exhibit No. 840 was marked for identification and received in evidence.)
Mr. Specter. I move formally for their admission, then, into evidence at this time.
Mr. Dulles. They shall be admitted.
Mr. Specter. Will you describe the three pieces of metal which are contained within this vial, please?
