In this short monograph the author first considers the sensory, motor and secretory functions of the stomach in health. The normal gastric sensations are described and explained. The variations in gastric secretion are considered as expressions of variations in tonus, peristalsis and motility. In health they may range from complete "achlorhydria" to extreme "hyperchlorhydria." A correlation is found between the physical type of the subject and the type of gastric response, both motor and secretory. An entire chapter is devoted to the function and control of the pylorus and to the control of gastric acidity. In gastric disease, the painful sensations are ascribed to an increase of tension in the muscle fiber and the suggestion is made that nausea and anorexia are associated with abnormal relaxation. A classification of the common dyspepsias is given and discussed. One chapter is devoted to gastrojejunostomy and its sequelae.
