INVERSION OF THE UTERUS. 
This is not of very frequent occurrence, and is usually 
met with in bitches which have parturiated several times, 
and in which the organ is loose and flabby and the os uteri 
relaxed. It is usually connected with protracted parturi- 
tion, where undue force or assistance has been used, or 
there has been violent straining. 
Symptoms.—Inversion of the uterus is denoted by the 
protrusion of a round rough-surfaced body, which is easily 
compressible ; the extent of the protrusion may be detected 
by examining with the finger between the tumour and 
walls of the vagina. If the inversion is protracted the 
organ becomes discoloured with a pus-like exudation on its 
exposed surface, and emits an offensive odour. 
Treatment.—This consists in returning the uterus to its 
proper situation, which should be done without delay, other- 
wise its swollen and abnormal condition will render it next 
to impossible. The operation is best effected by gentle 
pressure on the centre of the fundus with a rod having the 
end padded ; a little olive-oil or milk injected around and 
on the organ will facilitate its return. 
The after-injection of a weak solution of alum or zinc, 
and the administration of an opiate, will assist in the re- 
tention of the organ. 
When, owing to protracted inversion, the uterus has be- 
some enormously swollen, discoloured and cold,and return is 
impossible,excision will be necessary ; and this may be per- 
formed either by a ligature round the neck of the organ, 
gradually tightened every day, or direct removal with the 
knife immediately before a tight ligature. The subsequent 
treatment should consist in warm water injections, with 
occasionally chloride of zinc, laxative diet, and quietude. 
ULCERATION OF THE UTERUS 
Is not very frequently met with incanine practice. The 
“ Veterinary Record,” vol. iii, gives the following :—
