116 ANIMAL CASTEATION.

 If, besides these symptoms, we discover by rectal 

 examination that there is in front of and above the 

 pubes a tnnior more or less ovoid, or giving the 

 sensation of a cylindrical mass, of size varying to the 

 touch — which is the diseased indurated cord — the 

 case is Judged at once to be one of intra-ahdurtniial 

 nature. At times the inflammation may extend to 

 the sub-lumbar region, when the hand introduced 

 into the rectum may discover in that locality an 

 ovoid tumor or abscess which may l^e of great size.

 The abscess may sometimes 0])en externally, and in 

 some cases it may accumulate within the thickness 

 of the cord and form large collections ; or, again, it 

 may find its way into the al)dominal cavity, where it 

 may excite a fatal peritonitis. 



This rapid examination of the various forms of 

 deep champignon will enable us easily to realize the 

 difficulty of the progress in the case. While the 

 pedunculated form, exterior to the scrotum, is not, 

 comparatively, a very serious matter, it becomes, on 

 the contrary, a very grave occurrence when it assumes 

 the characters of the intra-abdominal variety, and 

 must in a majority of cases be recognized as an incu-

 which surgical interference cannot usually be dis-
