DISEASES OF THE GENERATIVE ORGANS. 131 



exercise daily is beneficial, as the protrusion is not so liable 

 to take place in the standing posture and during locomotion, 

 as in the recumbent position. Constipation, or any of the 

 causes which produce straining, must be avoided. 



POLYPUS IN THE VAGINA. 



Polypus is occasionally met with in the vagina of bitches. 

 It consists in a pedicled tumor , attached to some portion of 

 the vaginal walls. . It is generally situated some distance from 

 the orifice, and is usually observed when the animal is in a 

 lying posture. Sometimes it increases so much in size as to 

 be continually protruded, and the act of urination causes it 

 to be still more dependent. 



Polypus may be confounded with uterine inversion, but a 

 careful examination will at once remove this doubt, as its at-

 by a purulent discharge, but, as a rule, there is simply an in- 

 crease in the secretion of mucus. It creates much incon- 

 venience in the act of urination, and when of considerable 

 size interferes with the evacuation of faeces. 



Treatment. — Removal by excision or ligature, which is 

 attended with but little danger or constitutional disturbance, 

 and the injection afterwards of astringents, with occasional 

 application of lunar caustic, if unhealthy action or fungus re-

INFLAMMATION OF THE UTERUS (METRITIS). 



Bitches are not very frequently troubled with this affec-
