The new hydropathic cook-book : with recipes for cooking on hygienic principles : containing also a philosophical exposition of the relations of food to health : the chemical elements and proximate constitution of alimentary principles : the nutritive properties of all kinds of aliments : the relative value of vegetable and animal substances : the selection and preservation of dietetic materials, etc., o doubt completes the perfect solution ofthe alimentary matter. It should be mentioned, also, that the duodenum secretes afluid similar to, if not identical with, the gastric juice; and,indeed, some physiologists affirm that the solvent property ofthe duodenal secretion is equal to that of the gastric juice. Chylification.—The intestinal tube is divided anatomi-cally into the small and the large intestines. The small intes-tines, taken together, are about four times the length of thebody, and are subdivided into the duodenum, jejunum, andileum. The large intestines are subdivided into the caecum, colon,and rectum. Fig. <j3 is a view of the whole alimentarycanal. 1. Esophagus. 2. Stomach, o. Liver raised, show-ing the under surface. 4.

In a strict physiological sense the duodenum may beregarded as a second stomach, and the jejunum as a third;and we should scarcely trench on the field of imaginationif vre called the ileum a fourth; for through the whole lengthof the small intestines the process of digestion really goes on,a solvent fluid being secreted along their whole inner surface,though most copiously toward the stomach ; while lacteal vesbp]s, or chyle-carriers, open their mouths upon every portionof their mucous coat, though most abundantly toward thef-omach.
