On the Effect of Oxidizable Substance upon the Gaseous Metabolism of Normal Healthy or Scorbutic Animals.

1. The gaseous metabolism of normal healthy guinea pigs was increased by the administration of lotus rhizome juice or platan leaves juice. 2. The goseous metabolism of normal guinea pigs was slightly increased by the administration of testis extract, and more markedly so by the administration of lotus rhizome juice together with it. 3. The gaseous metabolism of guinea pigs fed with the basal diet free from vitamin C decreased with the diminution of their body weight, and it again increased transitorily by the administration of lotus rhizome juice. 4. The gaseous metabolism of the castrated male guinea pigs was increased by the hypodermal injection of "Spermatin".
