1. Extract of hilum ovarii has the opposite effect to extract of corpus luteum upon the movements of the rat's uterus, for it causes inhibition instead of contraction. The uterus of other animals is affected differently, for in the rabbit, cat, and guinea‐pig an extract of the hilum usually has the result of producing an increase of tone. 2. Liquor folliculi produces an increase of tone of the uteriine muscle in the rat, rabbit, and cat, or at any rate an increase in height of the rhythmic contractions. 3. When applied to the whole thickness of the intestinal tube, all the extracts tested—hilum, liquor folliculi, and whole ovary—determine an increase of tone, whereas a strip of the longitudinal coat of the rabbit's intestine is sent into relaxation by extracts of hilum. 4. A fall of blood‐pressure is produced by intravenous injection of all the extracts employed—hilum, liquor folliculi, and whole ovary.
