ON THE CASTRATION OF THE COW.

tends to threaten the life of the animal. In their turns, all means 
commonly effectual in like cases were employed, but never with 
complete success. I took advantage of the occasion to beg of the 
owner to give the cow up to me, seeing she would never more be 
of any value to him, in order that I might make her the subject of 
a second experiment ; and I was the more desirous for this, be- 
cause I wanted to ascertain what effect such an operation was 
likely to have on the disease she was suffering from. 
The operation succeeded as well as on the first occasion. The 
cow subjected to the operation on the 6th, gave on the 16th her 
usual quantity of milk, which a little while afterwards even be- 
came augmented. 
The prolapsus never appeared afterwards, and the animal fed 
better, and got fat. 
This satisfactory improvement lasted about fifteen months. At the 
end of this time the cow becoming stronger and her disease threat- 
ening to re-appear, she was sold to the butcher, notwithstanding 
she continued yielding the same quantity of milk. As in the case 
of my father’s cow, from the report of the dairy-maid, the milk 
was of superior quality. 
Experiment III. — Upwards of eighteen months passed before 
another subject offered. All my representations proved vain. I 
could not prevail on another cow-keeper to give me up one of his 
cows ; when, by chance, I happened to be talking with M. l’Abbe 
Charlier, director of Beth’leem, who, less wedded to old customs 
than fond of improvement, felt desirous of aiding me. 
A cow of little value he had in his stable was set a price on by 
us, and we agreed among ourselves to bear the loss, providing 
any thing happened to her. We were, however, not put to the 
test of any disagreement; for the animal in the course of a few 
days recovered, and shortly after gave her allowance of milk, 
which, as in the case of the other cows, proved more creamy and 
pleasant to the palate. For months afterwards the quantity of 
milk by degrees diminished, the cow beginning to grow very fat, 
without any augmentation of aliment. Soon afterwards her milk 
dried up. M. Charlier then sold her to the butcher, in whose 
hands she yielded abundance of fat, and meat of an excellent 
quality. A farmer of Rheims, M. Damoulin, who saw the cow 
before the operation, felt no hesitation in affirming that the cow 
had doubly increased in value. 
Experiments IV and V. — About the same period, M. Guillotin- 
Guillot, grazier at Mazilly, commune d’Hermonville, made trial of 
this operation on two cows at the same time. The success was as 
complete as in the former instance, notwithstanding one of the cows 
was about ten days gone with calf : she, however, languished, and
