630 ADVANTAGES OF SPAYING MILCH COWS. 
CASE II. 
A small cow, six years old, calved on the 26th of March, 1834, 
and at that time yielded two gallons and a half of milk per day. 
On the 30th of April she gave two gallons, and she was then 
spayed. She suffered little from the operation ; her milk did 
not diminish, and she yields the same quantity to the present 
day. She has not shewn any longing for the bull. 
CASE III. 
A little cow calved on the 12th of April, 1834. Some days 
afterwards she yielded two gallons of milk per day, and she was 
operated upon on the 13th of May. She seemed, for a consi¬ 
derable time afterwards, to be in a poor state of health ; her skin 
became yellow; the hair fell off in patches, and particularly 
about her fore-quarters. She moaned sadly from time to time, 
and her appetite considerably diminished. The quantity of milk 
remained the same. 
On June 20th she seemed to be really ill, and yielded, during 
seven days, little more than a gallon of milk per day. The 
quantity gradually lessened after that period, and continued 
to decrease until the end of July, when she was evidently drop¬ 
sical. She was sometimes better, and sometimes worse, until 
the 4th of September, when she died. 
Two pounds of a bloody serosity were found in the thorax. 
The lungs contained numerous tubercles; some hard, and even 
stony, and some soft, and others filled with purulent matter. 
On opening the belly it contained, at least, sevoii gallons of a 
similar fluid. The fourth stomach and some of the intestines 
were softened and black, and the food contained in the first 
stomachs was fetid. The liver, enlarged and yellow, was softened, 
and it also contained many tubercles, hard or soft. 
The womb was unaffected, except the extremities of the two 
cornua, which were of a yellow colour, and hard. Few traces 
of the operation of spaying remained, unless in the sublumbar 
region, in which a spot of a blackish colour was seen where each 
ovary had existed. A white tenacious tissue had united the 
incision made through the abdominal muscles, and caused the 
parietes of the abdomen to adhere strongly to the skin. 
This examination after death proved that the cow was not lost 
from any morbid consequence of spaying, but from ascites, pro¬ 
duced by the lesions stated, and which had existed before the 
operation.
