THE PEEITONETJM. 481 



With a view to the distinction of these several vestiges in the two sexes, 

 the following tabular enumeration of them is given, with the names proposed 

 by Waldeyer printed in italics, viz. : — 

 The upper or non-glomerular part of the AYolflian body forms — 



1. In the male, the Epididymis. 



2. In the female, the Parovarium, Organ of RosenmiiUer, or Eijoophoron. 

 The lower or primordial-kidney part of the "WoMan body forms — 



1. In the male, the organ of Giraldes. Parepididj-mis or Paradidymis. 



2. In the female, the Parooi)horon (Eierstock und Ei. p 142). 



THE PERITONEUM. 



The abdominal viscera having now been described, as well as the 

 disposition of the peritoneum in relation to each of tliem, it remains 

 to give an account of that membrane in its whole extent, and to trace 

 its continuity over the various parts which it lines or covers. 



After lining the anterior wall of the abdomen, the peritoneum passes 

 round on either side to the lumbar region, where it meets with the right 

 and left portions of the great intestine. On the right side it com- 

 pletely invests the lower rounded end of the ca3cum with the vermiform 

 appendix ; but the rest of the cajcum it covers only before and on the 

 sides, a part of the bowel behind, of variable extent, being immediately 

 adjacent to the iliac fascia, except in rare instances where the mem- 

 brane goes entirely round and forms a niesocajcum. It is disposed in a 

 similar manner on the ascending colon which is in immediate apposition 

 with the right kidney and other parts behind ; although here, too, 

 the investment may be complete with a resulting right mesocolon. 



Leaving the right colon, the peritoneum gives a scanty covering to 

 the anterior face of the right kidney and adjoining third portion of the 

 duodenum where that intestine comes down from behind the transverse 

 mesocolon ; lower down it continues over muscles and vessels to the 

 root of the mesentery, advances forwards to form the right layer of that 

 process, turns round the jejunum and ileum, affording them their perito- 

 neal coat, and returns back to the vertebrae, thus completing the mesen- 

 tery on the left side. The membrane now reaches the left colon, first 

 passing in front of the left kidney, which being less covered by colon 

 than the right one, gets more of the peritoneum. After investing the 

 left colon much in the same manner as the right, the peritoneum, thus 

 traceable horizontally round the abdomen, is continued over the lateral 

 wall on the left side. Where the colon forms its sigmoid flexure it is 

 completely invested by peritoneum, which attaches it by a compara- 

 tively free and moveable sigmoid mesocolon to the fascia of the left 

 iliac fossa. 



From this part, and from the lower end of the mesentery the peri- 

 toneum is continued into the pelvis. It there invests the upper part of 

 the rectum completely, forming a meso-rectum behind. Lower down 

 the membrane gradually quits the intestine, first behind, then at the 

 sides, and finally in front, whence it is reflected on the inferior fundus 

 and posterior part of the bladder in the male, and forms here the redo- 

 vesical pouch, the mouth of which is bounded by a crescentic fold on each 

 side, but larger on the left, tiie two being named pliccc semilunares, i'rom 

 the superior fundus the peritoneum passes to the recti muscles. Here
