INGUINAL HERNIA. 77 Fig. 60. Now, the next structure with which the testicle comes in contact, is the fascia transversalis ; let us follow this in its descent with the testicle, and observe the changes which it undergoes. It is not per- forated as most pictures represent, but pushed before the testicle, covering it and the cord. The point where this protrusion takes place, is midway between the anterior superior spinous process of the ilium and the pubes, and about an inch and a half above Pou- part's ligament, and is called the internal abdominal ring; but there is no hole or opening unless mad6 with a scalpel. The fascia is continuous from the abdomen upon the cord, although that portion covering the abdomen is tougher and thicker than that of the cord. If the cord is stretched, this portion of the fascia will resemble a funnel, and hence some call it the infundibiliform fascia. That portion which covers the testicle, assists in forming its cellular coat, which is termed by some tunica vaginalis communis testis, by others, fascia pro2:)ria. Terms are matters of minor importance; the truth to be taught is, that the testicle, cord, and abdomen are invested by the same fascia, having different names and dif- ferent thicknesses in different parts. The next layer of the abdominal wall with which the testicle comes in con- tact is the transversalis muscle. At the lower part of the abdomen, the in- ternal oblique is so much blended with the transversalis, that the two may be considered as having the same relation to the testicle in its descent, and also to hernia. At the internal abdominal ring, the testicle, already covered by the peritoneum and fascia transver- salis, comes in contact with these muscles; it does not perforate them, but pushes their conjoined lower edge before it, obtains for
