On the Immunity of Rattlesnakes to Their Venom

Abstract

c ATTLESNAKES are immune to their own and each other's venom. This frequently occurring statement stands alone in the literature without record of experimental work on which it might logically be based. Recently H. K. Gloyd' has recorded the fatal effects to a rattlesnake of the bite of a cottonmouth moccasin. He also reports on the observations on three other crotalid snakes bitten by themselves or by other snakes, and from which no harmful effects followed.
