    ON RETRO-PERITONEAL HERNIA CHAPTER I. THE DEVELOPMENT OF THE INTESTINAL CANAL AND PERITONEUM. The intestinal canal, at the beginning of the fourth week of intra-uterine life, consists of an almost straight tube, attached throughout its whole length by a dorsal or posterior fold of peritoneum to the middle line of the body (Fig. i). This fold is the primitive mesentery. In that portion of the canal which afterwards develops into the stomach is seen a dorsal bulging, which represents the greater curvature of that organ. It is to this curvature, therefore, that the primitive mesentery is attached. From the anterior (or ventral) portion of the stomach, and the beginning of the duodenum, a'second fold of peritoneum runs forward to be fixed into the anterior abdominal wall. In this fold, the small omentum, the liver is showing early signs of development. By the sixth week the intestinal tract can be seen to con- sist of three segments, each of which is the territory of a. special artery by which it is supplied (Fig. 2, a, b, c). The first segment consists of the stomach and duodenum, attached by the mesentery containing the cceliac axis. This primitive mesentery is known as the mesogaster, or, more properly, as the mesogastrioduodenum. The stomach is placed, with its lesser curvature, in front and to the right,
