Abstract
MAMMALIAN sperm have been reported by various workers to contain no nucleoprotamine or nucleo-histone extractable by the usual means (with water or neutral salt solutions)1. This has been confirmed in the case of the bull, man, dog, boar and ram, but basic protein and nucleic acid, having solubility properties quite different from the usual, have been extracted from the isolated heads of these cells.
