    spleen in the greater, the artery in question may be grasped. Recent works on anatomy (e.g., Quain's Anatomy, Ninth Edition, 1882, vol. ii, p. 729, fig. 621, &c.) delineate the peritoneum in accordance with the above description. The process of development which has been described seems to afford an explanation of the very complicated relations of this artery, both to the peritoneum and to its greater and lesser cavities. Diagram 3. S. Stomach. MG-. Mesogastrium. The arteria vasa brevia and gastro-epiploica sinistra are naturally the next to demand attention. It has been pointed out already that the gastro-splenic omentum is simply that part of the mesogastrium which lies between the spleen and the stomach. Blood- vessels are present in the mesentery of the stomach long before the appearance of the spleen, but it does not seem possible to say whether the vasa brevia are the representatives of these, or whether, as was remarked before, they might have been developed in connexion with the spleen itself. Similar doubts appear to exist when the epiploic arteries are in question; how far they are prolongations of the original arteries of the mesogastrium, or to what extent they are developed in the mesoblast which surrounds the stomach. A solution of this point would in no way affect what has been said about the course and relations of the splenic artery itself. This vessel is exceedingly like the gastric, for it has a similar origin and similar course through the mesogastrium. The arteries in the vicinity of the pylorus are the next to demand notice. The development of the liver and lesser omentum has a pro- found influence upon these, and therefore requires ample considera- tion. Owing to difficulties which have been mentioned before their development will be studied in the chick. The very earliest stages of the development of the liver determine its arterial supply. A trans-
