if the aborting cow is kept on, she becomes insusceptible and carries her 
calf to full time. A cow may therefore be infecting to others though she 
herself no longer aborts. 
(3) Dissolve 1 dram corrosive sublimate, 1 ounce each of alcohol and 
glycerine, and shake this up in a gallon of water, to use as an injection 
into the vagina and a wash for the parts about the vulva and root of the 
tail. Being very poisonous, it should be kept in a wooden barrel out of 
the way of animals or children. Every morning the vulva, anus, back 
of the hips, and root of the tail should be sponged with this liquid, and 
this is best applied to the whole herd. A 1 per cent solution of carbolic 
acid is a good substitute. 
(4) When any case of abortion has occurred the fetal membranes must 
be removed by the hand without delay, and, together wtih the fetus, de- 
stroyed by burning or boiling, or buried deeply, and the stall should be 
cleansed and watered freely with the copper solution. Then the womb 
should be washed out with li/^ gallons of the corrosive sublimate solution 
injected through a rubber tube introduced to the depth of the womb and 
with a funnel in its outer elevated end. This should be repeated daily 
for a week. In the case of the other non-pregnant cows of the herd one 
injection of the same kind should be made into the vagina, after which 
they need only have their external parts and tail washed with the solu- 
tion daily. 
(5) Do not breed aborting cows for two or three months, then use a 
separate bull, injecting his sheat and washing his belly before and after 
each service with the carbolic acid solution. Exclude all outside cows 
from service by the regular herd sire and, in purchasing breeding ani- 
mals, subject them to quarantine and treatment before placing them in 
the sound herd. 
As a certain number of the cows will harbor the germ in the womb 
when treatment is started, it is not to be expected that abortions will 
cease at once, but by keeping up the treatment the trouble may be got 
rid of in the following year. As an aborting cow is usually of little use 
for the dairy, it is best to separate and fatten her and apply treatment 
to those that remain. In this, as in other delicate manipulations, the 
stock owner will consult his own interest by employing an accomplished 
veterinarian and avoiding such as have not had the privileges of a thor- 
ough professional education. In addition to the above, the removal of 
all manure and contaminated litter and the sprinkling of the surface 
with the sulphate of copper solution is called for. Drains should no less 
be thoroughly rinsed and disinfected. Milking stools, and other imple- 
ments may be treated in the same way, or with carbolic acid or boiling 
water. Great care should be taken to guard against bull or cows from an 
aborting herd or district; streams even may be suspected if there is an 
aborting herd near by and higher up on that stream. Cows sent to bull 
from an aborting herd are to be positively denied, and worknlen that 
have attended on such a herd should be made to wash and disinfect their 
clothes and persons.
