First Editions. GM 2104; 2106. Mitchell (1829-1914) and Reichert showed snake venom to be protein in nature, and demonstrated the presence of toxic albumins. Mitchell was one of the first to investigate the snake venoms; he was the first to point out that snake venom is a double, not a single poison. Hideo Noguchi's great work, done many years later, had its origin in Michell's early researches.
Condition: Very Good
