204 ABDOMINAL VISCERA IN MAN. 



and passes downwards to the right, crossing the middle line 

 rather over half-way between CD. and E.F., or nearly H inches 

 above the umbilicus, to its lower attachment, which is situated 

 midway between the plane of CD. and that of the anterior 

 superior iliac spines, nearly an inch inside the light lateral line. 

 The peritoneum is reflected on to the inner side of the ascending 

 colon in the plane of CD. just outside the right lateral line and 

 continues upwards, and a little outwards, to midway between 

 the planes of CD. and E.F., where, forming the lower layer of 

 the transverse meso-colon, it turns inwards, crossing the middle 

 line a little over an inch below E.F,, whence ascending, it reaches 

 the plane of E.F. a little over an inch to the left of the middle 

 line, and continues outwards in the plane of E.F. to an inch 

 beyond the left lateral line, where it bends downwards, inclining 

 inwards, eventually crossing the plane of CD. just outside the 

 left lateral line. It now passes downwards and inwards to the 

 pelvic brim to about the level of the anterior superior iliac 

 spine, a little inside the left lateral line, whence it bends 

 upwards again to a point just below CD. about half-way 

 between the middle line and the left lateral line, where it 

 finally turns downwards beside the sacral promontory into 

 the pelvis to become the meso-rectum.
