ABDOMINAL VISCERA IN MAN. 289 



The upper lorder of the transverse colon in the left lateral line 

 is at the level of E.F. 



The upper border of the S2)lenic flexure of the colon is a little 

 internal to a line drawn vertically upwards from the left anterior 

 superior iliac spine about an inch and a half above E.F. 



The descending colon commences an inch below E.F., a little 

 further outwards than the preceding. Half-way between E.F. 

 and CD., at the lower pole of the left kidney, its inner border 

 nearly reaches the left lateral line. In the plane of CD. its 

 outer border is situated nearly as far outwards as its commence- 

 ment, and little below CD. — half an inch — it becomes the 

 sigmoid flexure. 



The sigmoid flexure becomes possessed of a free mesenteric 

 attachment in the left lateral line in the plane of the anterior 

 superior iliac spine. 



The rect'um commences a little to the left of the middle line, 

 at the level of the anterior superior iliac spine.
