1. When goats and sheep are starved for periods up to 48 hrs., gastric juice of high acidity continues to be secreted by abomasal pouches, although the volume and acidity may be less than under normal conditions. 2. This continuous secretion is probably due to stimulation of the gastric glands by food material, since ingesta can be collected from the abomasal fistulæ in sheep and goats during starvation periods up to 48 hrs. 3. In unanæsthetized animals, if ingesta are prevented from entering the abomasum by emptying the fore‐stomachs, secretion of acid gastric juice ceases. 4. Similarly, when ingesta are prevented from entering the abomasum of anæsthetized lambs by ligating the omasum, the abomasal secretion is small in volume and appears to consist largely of mucus. 5. It is concluded that the continuous secretion of gastric juice which occurs in ruminants is not due to the innate ability of the gastric glands to secrete spontaneously but to specific stimuli, the most important of which is the continuous passage of ingesta from the rumen to the abomasum.
