- 1. The various units of B assay have been compared by means of feeding tests with crystalline vitamin B.
- 2. The effects on growth of increasing doses of crystalline B, ranging from 0.5
to 160
per day, have been observed.
- 3. The stimulative effect persists up to and probably beyond a dosage of 160
, an amount 80 to 160 times that necessary for maintenance of life.
