- 1. The presence in yeast of an antithyrotoxic factor, which has been previously reported, has been confirmed in these studies.
- 2. Liver has been found to be a better source of the antithyrotoxic material than yeast. This factor is not one of the known B vitamins. It is heat stable and under the experimental conditions employed is not destroyed by autoclaving in acid or alkaline solution.
- 3. Calcium pantothenate and inositol did not exert an antithyrotoxic effect when fed at very high levels in a purified ration.
