A review of the literature on the gastrointestinal tract covering 1937 and the first half of 1938 must present at best a composite picture. Owing to the complicated mechanism by which the digestive tract is controlled, it is obvious that searchers after more or less isolated facts must frequently be at variance. The known variables involving the processes of digestion are becoming increasingly more numerous. Because of this fact it is more and more difficult to draw definite and lasting conclusions as to etiologic or physiologic processes.
From the anatomico-pathologic point of view little new has been added during the period covered, although there has been a constantly increasing number of observations on some of the rarer conditions. Observations based on clinical studies or animal experimentation obviously represent attempts to elucidate certain fundamentals, and discrepancies between individual investigations still serve to show how delicate and how involved is the motor
