'15'1 DADD'S VETERINARY MEDICINE AND SURGERY. 



performed, it is said, with success, on many animals, and is pro- 

 posed as a safe and less painful process than the emasculation of 

 the horse. It consists in a longitudinal section through the scro- 

 tum, dartos, and vaginal sheath, so as to expose the cord, from 

 which the vas deferens is to be separated and severed from the 

 artery and vein. There is a. certain consent of parts, by which 

 the sympathy of an organ remains after its functional offices are 

 apparently destroyed. There can be little doubt but the nervous 

 excitement would continue, the vein and artery remaining entire. 

 There are certain nice conditions of the organ necessary for prop- 

 agation. Thus, the horse who retains his testicles within his abdo- 

 men, possesses all the roguish qualities of him with one perfectly 

 evolved ; he is lustful, and can cover, but is seldom fruitful. 



Of the morbid consequences of castration we have little to say. 

 By early evacuations, green food, a loose box, a cool air, moderate 

 clothing, but, particularly, by walking exercise, swellings of the 

 parts may be prevented ; if not, bleed and foment. Should sup- 

 puration follow, and sinuses form, treat as directed under those 

 heads ; and if tetanic symptoms start up, refer to that article. 

 There has been lately practiced in India a novel mode of castra- 

 tion, which is said to be the invention of a Boer, settled at the 

 Cape of Good Hope. The cord is exposed in the usual manner. 

 From the cord the artery is singled out. This vessel is scraped 

 through with a coarse-edged, blunt knife, when the other constitu- 

 tents of the cord are cut away, and the operation is finished. This 

 method is much praised by those who have adopted it, and is said 

 to be always attended with success. 



Lithotomy. 



Hurtrel d'Arboval's account of the progress of lithotomy in vet- 

 erinary practice commences in 1774; the second case was success- 

 fully operated on in 1794 ; and at later periods other veterinary 

 surgeons have also performed it. In monodactyles there are two 

 methods of operating for the stone — one through fhe rectum, the 

 other through the bladder. The first, which consists in laying 

 open the bladder by a longitudinal incision made through the 

 parietes of the part of the rectum adherent to it, by means of a 

 straight bistoury, is easily practiced, but in its consequences is 

 dangerous in the extreme ; in fact, it is an operation never to b<»
