166 DISEASES OF CATTLE. 



taken by a skilled veterinary anatomist, but the hints given above 

 may be valuable in showing the stock owner when he is being properly 

 served in such a case. 



In outlying districts, where no skilled operator can be had, a trans- 

 verse incision may be made with a clean sharp knife through the root 

 of the penis, just over the arch of the hip bone, when the urine will 

 flow out in a full stream. The attendant bleeding may be ignored, or 

 if profuse it may be checked by packing the wound firmly with cotton 

 wool for some hours. The urine will continue to escape by the wound, 

 and the ox should be fattened for the butcher. 



The immediate relief is not to be looked upon as a permanent cure, 

 as the calculi in the affected ox are usually numerous, and later attacks 

 are, therefore, to be looked for. Hence it is desirable to fatten and 

 kill such cases after a successful operation. If a breeding animal is too 

 valuable to be killed he should be subjected to preventive measures, as 

 laid down under Stone in the Kidney. 



It should be added that when the bladder is filled with a soft magma 

 a catheter may be introduced through the whole length of the urethra, 

 to be employed in pumping water into the bladder. This water is 

 extracted through the same channel when it has been charged with 

 the suspended solids by manipulations of the bladder with the oilep 

 hand introduced through the rectum. 



Calculi or grarel in the prepuce or sheath. This is usually a collection 

 of gravel, or a soft putty-like material which causes a distinct swelling 

 of the sheath and gives it a soft, doughy feeling when handled. It may 

 be removed in part by the oiled fingers introduced into the cavity, 

 assisted by manipulation from without, or a tube may be inserted 

 behind the collection and water pumped in until the whole mass has 

 been evacuated. Should even this fail of success the sheath may be 

 slit open from its orifice back in the median line below until the offend- 

 ing matter can be reached and removed. In all such cases the interior 

 of the sheath should be finally lubricated with sweet oil or vaseline. 

 It is unnecessary to stitch up the wound made in the sheath. (See 

 Inflammation of the Sheath.)
