PROLAPSE OF THE VAGINA. 
irrigation of the vagina with dilute acetate of alumina, which is also said to 
be a useful prophylactic against infection, and for this purpose is syringed 
into the bull’s prepuce. Wilhelm gives 75 grains of salicylic acid in about 
ljr pints of linseed tea once daily, discontinuing it on the fifth or sixth day, 
and later repeating the course two or three times. Frick saw in cows an 
epizootic catarrhal disease of the vagina which was spread by coition, and 
was frequently followed by failure to conceive. Recovery followed vaginal 
irrigations with per cent. liq. alum, acet., but only after a long time. 
Dieckerhoff noted a severe infectious vaginitis in cows and mares. Cows 
affected by it invariably perished ; and though the disease was less severe in 
mares, some of them' also died. The disease (kolpitis perniciosa, D.) set in 
with fever, and the vaginal inflammation was associated with a tendency to 
the formation of blisters and ulcers. A blood-stained exudation was found in 
the abdominal cavity on post-mortem. The disease developed after a short 
incubation period (twelve to twenty-four hours), and generally proved fatal in 
a few days. Disinfection of the vagina with carbolic or creolin solutions had 
no visible effect. In this case also the disease must principally be combated 
by protective measures. 
II.—PROLAPSE (INVERSION) OF THE VAGINA. 
PROLAPSUS (INYERSIO) VAGINAE. 
As above indicated, the term “prolapse,” though sanctioned by 
custom, is incorrect; strictly speaking, the condition is that of inversion, 
as is recognised in the French title, “ renversement du vagin.” 
Prolapse of the vagina is most frequent in cows and sows, rarer in 
mares. 
The disease depends on displacement of the uterus backwards and 
stretching of its ligaments—conditions usual after repeated pregnancies. 
It is favoured by tympanites, distension of the abdomen, continuous 
stall-feeding on distillers’ grains; distension of the abdomen, pressure 
of the foetus, severe straining on the part of the animal, and particularly 
by standing in sloping stalls ; it is seldom seen when animals are in the 
open. It is commonest in pregnant subjects, especially during the latter 
period of pregnancy, though it also occurs after parturition. In pregnant 
animals the vagina appears beyond the vulva when the animals are lying 
down, but disappears immediately on rising. Strictly speaking, the 
disease consists of eversion of the vagina, in which the upper wall is 
most frequently displaced. When the vagina only attains the vulval 
opening, a round red swelling of varying size, covered with mucous 
membrane, appears (incomplete prolapse). Less frequently a large 
portion of the vagina protrudes beyond the vulva, in which case the 
opening of the uterus is visible in the middle of the swelling, which is about 
as large as a man’s head, and displays, on its lower surface, the opening 
of the urethra. In prolapse of some duration, the surface of the mucous 
membrane, previously of a rose-red colour, gradually dries, and not
