220 EXPERIMENTS ON THE EFFECTS OF SPAYING COWS. 
which, however, yielded to methodical treatment, so that thirty- 
five hours after the cow gave nearly seven quarts of milk. And 
this quantity varied little for eight consecutive months, excepting 
during eight days while she was at sowing work, which was 
excessive. For the first fortnight of the ninth month there was 
noticed, notwithstanding she preserved the best health and con- 
dition, a slight diminution. This diminution becoming more 
and more apparent, reached its minimum at the end of the tenth 
month. Five weeks afterwards the cow was sold to the butcher, 
nearly fat. The quality of her milk had never undergone any 
important diminution, nor had the cow ever had any return of 
bulling. 
Second Experiment. — An Auvergne cow, six years of 
age, a good milker and hardy worker, calved 20th Sept. 1838, 
and was spayed 26th Oct. following. In the course of the day 
she had some slight colliquative pains. Four days after the 
cow gave the same quantity of milk as before the operation ; a 
quantity which experienced no variation for ten months and 
seven days: forty days after this, however, her milk sensibly 
diminished, and in sixty days more, being in fat condition, she 
was handed over to the butcher. It was remarked that the 
slightest work fatigued her ; that her milk yielded little butter ; 
and that she shewed some desire for the male. 
Third Experiment. — A cow of Aubrae, six years old, in 
full vigour, calved prosperously 12th April, 1839, and three 
days after yielded nearly seven quarts of milk. The 20th May 
following she was spayed, and on the fifth day afterwards died. 
Autopsy unreported. 
Fourth Experiment. — A cow of Auvergne, three years of 
age, had calved for the first time 2d April, 1840, and on the 
eighth day following had given about seven quarts of milk. On 
the 24th April she was spayed. For four days there was no 
rumination, — anorexia ; but three quarts of milk, of a serous 
character, could be drawn from her. She took antiphlogistic me- 
dicine, and on the 6th May had recovered her wonted health, 
and gave eleven quarts of milk daily. This quantity was 
maintained with little variation up to the 1st Oct. following. 
On the second day of seed-time she was forced to be returned 
to the stable on account of shortness of breath. From that time 
she grew imperceptibly dry, and was subsequently sold in very 
good full condition. The quantity of milk she gave called for 
no remark. She experienced no return of the oestrum. 
Fifth Experiment. — Cow of Auvergne, ten years old, 
giving on an average four gallons of milk daily. The work she 
did was but little, and she had calved for the sixth time on the 
20th May, 1842. The 29th June following she was spayed,
