Gastric secretion rate was estimated quantitatively after a fluid meal com-posed of milk protein, fat, and lactose and was found to be moderate. The constant secretion rate was not influenced by addition of 10 per cent glucose to the meal. Correction was made for duodenal reflux. Constant relations were found to exist between gastric volumes, secretion, and emptying for a considerable time in each experiment, with deviations in the beginning and at the end. Addition of 10 per cent glucose slowed the emptying during the first hour after ingestion of the meal, resulting in a slower decrease of gastric volumes.
