In a previous article1 we described a method by which it was possible to estimate the amount of gastric juice secreted and discharged from the stomach in successive ten minute periods following the introduction of a standard stimulus (alcohol). We have now examined a considerable number of people with and without gastric symptoms and the present article deals with some of the data derived from these studies.

However, in dealing with patients with digestive symptoms when a diagnostic problem exists, it would be misleading to compare with a supernormal standard, and what one
