On November 23, 1963, at 1:35 a.m., the two metal fragments in this container were delivered to me in the FBI laboratory by Special Agent James W. Sibert, and Special Agent Francis O'Neill of the Baltimore office of the FBI who stated they had obtained these in the autopsy room at the Naval Hospital near Washington, D.C., where they were present when they were removed from the head of President Kennedy. Mr. SPECTER. Is there any specification as to the portion of the President's head from which they were removed? Mr. FRAZIER. No, sir; they told me that there had been numerous particles in the head but only these two had been removed, the others being very small. Mr. SPECTER. May it please the Commission I would like to have those marked and admitted into evidence as Commission Exhibit No. 843. Mr. DULLES. It shall be so marked and admitted under those numbers. (Commission Exhibit No. 843 was marked for identification and received in evidence.) Mr. SPECTER. In the event we have not already had 842 admitted into evidence, I move, Mr. Dulles, for the admission into evidence of 842 which was the fragment from Governor Connally's arm. Mr. DULLES. That shall be admitted. Mr. SPECTER. Moving back to 843 will you describe those fragments indicating their weight and general composition? Mr. FRAZIER. These fragments consisted of two pieces of lead, one weighed 1.65 grains. The other weighed .15 grain. They were examined spectrographically so their present weight would be somewhat less since a very small amount would be needed for spectrographic analysis. Mr. SPECTER. Was a comparison made between or among these two fragments with the other metal from the bullets heretofore identified as Commission Exhibits 399, 567, 569, 840, and 842? Mr. FRAZIER. Yes; they were. Mr. SPECTER. What did that examination disclose? Mr. FRAZIER. Possibly my numbers do not agree with those you have. These two particles from the President's head were compared with the lead of Exhibit 842. Mr. SPECTER. Which is the fragment from the arm of Governor Connally? Mr. FRAZIER. Yes, sir; they were compared with the lead scraping from the inside of the windshield. Mr. SPECTER. Which is Exhibit 841. Mr. FRAZIER. And with the three lead fragments found on the rear floorboard carpet of the limousine. Mr. SPECTER. Which is Exhibit 840. Mr. FRAZIER. And they were found to be similar in metallic composition. Mr. SPECTER. Can you state with any more certainty---- Mr. FRAZIER. Excuse me, one thing. These, as a group, were compared with the bullet fragment, Commission Exhibit 567, which was found on the front seat of the automobile, which also was found to be similar in metallic composition. Mr. SPECTER. Is it possible to state with any more certainty whether or not any of those fragments came from the same bullet? Mr. FRAZIER. Not definitely, no; only that they are of similar lead composition.
