These reels show experiments in would ballistics, with missiles fired into water, gelatin, mammals, frogs, and fish. Dr. Edmund Newton Harvey was best known for his research on bioluminescence, but he also conducted applied research in areas such as wound ballistics and aviation physiology. In these experiments, Harvey is investigating the large cone-shaped temporary cavity that results after a projectile passes through tissue or other substances. The temporary cavity is many times larger than the permanent cavity observed after the completed passage of the projectile. The huge cavitation results in a displacement and tearing of tissues at a considerable distance from the missile track and is an important factor in producing a wound. The damage is caused by extreme stretching around the temporary cavity; similar stretching at gas pockets is also a source of damage.
