150 PRINCIPLES OP VETEEINAEY SUEGEEY 



treatment for prolapse of this sort is not always successful, as 

 the parts will continue to appear externally, and amputation 

 may become necessary. 



Prolapse of the Uterus. Most frequently seen in the cow. 

 It follows almost invariably anything which induces the 

 animal to strain persistently, such as rough empirical traction 

 ■during labor, the weight of the partly detached foetal placenta 

 hanging from the vulva, etc. Sometimes considerable trouble 

 is experienced in retaining the parts after they have been 

 returned : so much so, thait amputation of the uterus may be 

 required. 



Prolapse of the Vagina. Most frequently seen in the cow 

 and bitch. As causes may be given relaxation of those organs 

 which fix the vagina, as, at the latter stage of pregnancy, 

 cows standing on floors sloping downward, difi&oult labor 

 with traumatic lesions of the vaginal canal. The treatment 

 consists in reposition of the parts and retaining them by a 

 variety of trusses. 



Prolapse of the Penis. In cases of paraphimosis the 

 penis cannot be retracted and therefore becomes prolapsed ; 

 as also in paralysis of the penis. This form of prolapsus is 

 most frequently seen in the horse and dog. The treatment 

 consists in attempting reposition of the organ by hand, next 

 by antiphlogistic measures, and when they fail, in amputating 

 the prolapsed portion. 



Prolapse of the Tongue. Follows paralysis or lacera- 

 tions of the muscles. Treatment is unsatisfactory. 



Prolapse of the Bulb of the Eye. Seen in large-eyed 

 dogs, as pugs, following bites, etc. Treatment lies in reposi- 

 tion, or, in case the life of the tissues is destroyed, in 

 amputation.
