Abstract

1. Injection of the extract obtained from four ox pituitaries, intravenously or subcutaneously, produces a marked increase in the amount of secretion yielded by the mammary gland of the goat when milked fifteen minutes after the injection. 2. This increase is followed by a corresponding decrease below normal at the next milking several hours later. 3. As pointed out by Hammond, there is also a marked rise in the fat content of the milk secreted after injection, but there is no sudden fall in the percentage of fat at the next milking, as was observed by this investigator. 4. The solids‐not‐fat of the milk do not appear to be affected by the extract.
