    the transverse mesocolon would consist of only two layers, which would embrace the gut and ibs artery. The paper which has been mentioned was written, and specimens were shown, to demonstrate that this was what took place. If this evidence is true, the usual accounts of the relations of the transverse mesocolon and its contents require to be modified. It may be remembered that a little while ago it was said that it would be convenient to defer the final stages of the development of the pancreas. When this organ was last spoken of it lay between the folds of the mesogastrium just before this membrane was attached to the spine (Diagram 5). In consequence, the fossa between the meso- DlAGEAM 8.

To show the last stage in the disappearance of the fossa between the omentum and transverse mesocolon. gastrium and the mesentery of the transverse colon intervened between it and the spine. It is clear that if the highest part of the peritoneal loop which forms this fossa was withdrawn, the pancreas would naturally apply itself to the spine (Diagrams 6 and 7). That this is what occurs need not be repeated, and as the under surface of the mesogastrium is continuous with the left surface of the mesoduodenum, the drawing out of the one causes the disappearance of the other. All the arteries of the alimentary canal from the stomach to the rectum have now been discussed, and I have maintained that— First. All of them, even the splenic and hepatic, were originally derived from the dorsal aorta for the supply of the mid-gut. Second. That they reach their destinations bypassing through the mesentery.
