connected to the lever, pulls the tape from its roll and dispenses it. Such dispensers are usually found only in commercial establishments. A dispenser of this type was located in the Texas School Book Depository shipping room. The length of the lines and the number of lines per inch on the tape from the paper bag was identical to the length of the lines and the number of lines per inch on the tape obtained from the dispenser in the Texas School Book Depository shipping room.254

WOUND BALLISTICS EXPERIMENTS

Purpose of the Tests

During the course of the Commission's inquiry, questions arose as to whether the wounds inflicted on President Kennedy and Governor Connally could have been caused by the Mannlicher-Carcano rifle found on the sixth floor of the Texas School Book Depository Building and Western Cartridge Co. bullets and fragments of the type found on the Governor's stretcher and in the Presidential limousine. In analyzing the trajectory of the bullets after they struck their victims, further questions were posed on the bullet's velocity and penetration power after exiting from the person who was initially struck. To answer these and related questions, the Commission requested that a series of tests be conducted on substances resembling the wounded portions of the bodies of President Kennedy and Governor Connally under conditions which simulated the events of the assassination.

The Testers and Their Qualifications

In response to the Commission's request, an extensive series of tests were conducted by the Wound Ballistics Branch of the U.S. Army Chemical Research and Development Laboratories at Edgewood Arsenal, Md. Scientists working at that branch are engaged in full-time efforts to investigate the wound ballistics of missiles in order to test their effects on substances which simulate live human bodies.255 The tests for the Commission were performed by Dr. Alfred G. Olivier under the general supervision of Dr. Arthur J. Dziemian with consultation from Dr. Frederick W. Light, Jr.256 Dr. Olivier received His doctorate in veterinary medicine from the University of Pennsylvania in 1953. Since 1957 he has been engaged in research on wound ballistics at Edgewood Arsenal and is now chief of the Wound Ballistics Branch.257 His supervisor, Dr. Dziemian, who is chief of the Bio-physics Division at Edgewood Arsenal, holds a Ph.D. degree from Princeton in 1939, was a national research fellow in physiology at the University of Pennsylvania and was a fellow in anatomy at. Johns Hopkins University Medical School.258 Since 1947, Dr. Dziemian has been continuously engaged in wound ballistics work at Edgewood Arsenal.259 In 1930, Dr. Light was awarded an M.D. degree from
