    bution. The inner side of the external iliac, quite close to Poupart’s ligament, furnishes a branch, ^-th of an inch in diameter, which, in¬ clining inwards over the external iliac vein, meets with the spermatic cord, and ramifies upon it in the inguinal canal, thus representing the cremasteric branch of the epigastric artery. All the small ves¬ sels are well filled with ordinary injection, but no communication of the cremasteric branch, nor of the external iliac trunk, with the epi¬ gastric artery, can be found. The internal iliac artery runs downwards without giving off any branch for l|d inch, reaching nearly to the upper edge of the sacro- sciatic notch. It then furnishes the following branches:— 1st, From its right side and in front, a common trunk for the epigastric and obturator arteries, or an epigastric artery which fur¬ nishes the obturator in its course. 2d, From its posterior part, an ilio-lumbar artery of large size. 3d, From the front of the artery, a little lower down, a common trunk for the partially obliterated hypogastric, the pudic, and middle haemorrhoidal arteries, with a small vessel, which runs out of the pelvis at the upper part of the sacro-sciatic notch, giving off a small branch, which runs forwards on the surface of the obturator-internus muscle, and divides into two branches, the higher of which is not far from the usual position of the obturator artery, and anastomoses by small branches, with a descending branch of the obturator given off close to the obturator-foramen; whilst the lower division runs downwards and forwards to anastomose with a branch ascending from the pudic to join with the small descending branch of the obturator. 4th, The internal iliac gives off a small vessel, which passes obliquely upwards and outwards over the brim of the pelvis into the substance ol the iliacus muscle, and anastomoses in it with the ilio-lumbar artery. 5th and 6th, Two lateral sacral arteries pass off from the posterior part of the iliac, the higher in position entering the first anterior sacral foramen; the other inclining downwards, and furnishing branches which pass into the other sacral foramina. 7th, The internal iliac divides, at the distance of 2-J inches from its origin, into the gluteal and ischiadic arteries; the gluteal passing be¬ tween the lum bo-sacral and the first sacral nerves, and escaping from the pelvis at the upper part of the sacro-sciatic notch, breaks up into branches at l-|d inch distant from its origin; the ischiadic passing between the first and second sacral nerves, leaves the pelvis lelow the pyriformis muscle, and has its usual distribution.
