of using the truss; the quilled suture is the best, and 

 the ligatures must be stout, so as not to readily tear

away ; a good hold also must be taken. All measures failing 

 to effect the return of the protruding organ, it may be 

 amputated. This operation, Amjputation of the Uterus, 

 has often been successfully performed The neck being 

 constricted by an ordinary ligature, the greater part of 

 the organ may be removed with the knife or with the 

 heated iron, or the method of caustic clamp or elastic 

 ligature may be tried, and the use of the ecraseur has 

 been suggested for this purpose. The patient will require 

 to be cast in the usual way and the operation be performed 

 under chloroform. 



Prognosis in cases of prolapsus uteri must be considered 

 favorable. In many cases the recovery is so perfect as to 

 make the animal useful for breeding purposes afterwards, 

 but such animals should always be carefully watched during 

 parturition and the truss applied directly the foetus has 

 passed. Death may take place through shock on ampu- 

 tation, or from mortification of the protruded organ. 

 An animal which has once been thus affected, can be 

 returned to the vendor, according to the law of some 

 countries. 



Inversion op the Yagina is a frequent accompaniment 

 of prolapsus uteri, and cannot be said to render the case 

 more complicated. Sometimes it is seen as a distinct 

 lesion ; then there is a red tumour hanging from the vulval 

 opening which presents no cotyledons, has an opening at 

 its fundus, and at its lower part may be seen the orifice 

 of the urethra. It is not difficult to return this after 

 cleansing, but the accident is very liable to recur, there-
