Fig. 6.—Rabbit-uterus, Showing increase of tone and increased rapidity of rhythmiccontractions as the result of immersion in corpus luteum extract (5 per cent.). in both cases was increase of tone, sometimes accompanied by an increasedrate of the rhj^thmic contractions. Fig. 6 may be given as an example ofthis result. Inhibition was evident in two cases, one non-pregnant andone pregnant. After two days in the ice-chest the ordinary result wasstill obtainable. A few experiments were made with the rabbits uterus insitu, an injection of extract being made into the jugular vein.

Fici. 7.—KHect of corjius hiteuiii extract iij)oii tlie coiiliactioii f tin-rabbits uterus ^in situ):10 c.c. of a 1 ))er cent, extract of dried corpus luteuru was injected intravenously. This jiro-duced at first a contraction of a somewhat prolonged character. Experiments upon the Cat.s Uterus. A few experiments were made with the cat, one upon a pregnant uterus,the rest non-pregnant. The usual result was as with the rat, increase oftone, both with the fresh uterus and with that which had been kept in theice-chest, although to a much less extent in the latter case. The increaseof tone might be accompanied by acceleration of the rhythmic movements.In one of the experiments there was diminution of tone. The increase oftone is shown in fig. 8; diminution in fig. 9. Experiments upon the Dogs Uterus. Only one experiment was made; upon a bitchs uterus. In this casethere was both an increase of tone and an increased rate of frequency ofthe rhythmic contractions (fig. 10). Experimen
