ger carried up into the lateral fornix, posterior to the cer- 

 vix, and then pushing out towards the lateral wall of the 

 pelvis while deep pressure is made, with the other hand, 

 through the corresponding semi-lunar line. The ovary 

 feels like a firm body about as big as the end of the thumb 

 and is freely movable in all directions. 



The Fallopian tubes are not, normally, readily felt, but, 

 when diseased, they may be rolled, cord-like, by the fin- 

 ger, behind the ovary and the uterus. 



The Sigmoid Flexure and the Rectum. 

 The latter was formerly divided into three portions but it 

 is better to include the first portion with the sigmoid flex- 

 ure, which, Omega-shaped, and about seventeen and a 

 half inches in length, begins where the descending colon 

 ends, viz., on the outer side of the psoas magnus muscle, 

 in the iliac fossa. The sigmoid, after crossing the psoas 

 magnus muscle at right angles, and about midway 

 between the promontory of the sacrum and Poupart's 

 ligament, terminates where the original second part of 

 the rectum began, viz., opposite the third sacral vertebra. 

 The most of the sigmoid flexure is contained in the pelvis 

 and lies more or less in contact with the bladder and uter- 

 us. Its meso-colon is from one and a half to three and a 

 half inches wide, i.e., from posterior wall to bowel, and 

 the line of its attachment to the former, as seen when the 

 sigmoid is removed, runs across the psoas muscle to the 

 point of bifurcation of the iliac artery, and thence, with a 

 slight curve, reaches the middle line of the body opposite 

 the third sacral vertebra. 



The Rectum extends from the third sacral vertebra 

 to the anus, the first portion reaching from the third sacral 

 vertebra to the tip of the coccyx, and the second portion 

 from this point, to the anus. The first portion, about 

 three and a half inches in length, is covered by peritoneum
