rrupted suture. The animal recovered from the influence of the
anaesthetic in about fifteen minutes, when she was allowed to rise, and
walk back to her stall.

Upon the morning of the second day succeeding the operation, the animal
was visited and found to be in good spirits, apparently suffering very
little pain or inconvenience from the operation, and the wound healing
nicely.

Since that time, he has operated upon some twenty cows, all of which,
with a single exception, have thus far proved satisfactory.

Several of these cows are under the direction of a committee from the
Philadelphia Society for promoting Agriculture, whose duty it is to have
a daily record kept of each cow's yield of butter and milk, for one year
from the time of spaying. Their report will be perused by the
agricultural community with much interest.

The author's own experience will not justify him in speaking either in
favor of, or against, this operation; as sufficient time has not as yet
elapsed to satisfy him as to its relative advantages and disadvantages.
He, however, regards the operation as comparatively safe. The French
estimate the loss at about fifteen per cent., and the gain at thirty per
cent. Of those upon which he has operated, not a single animal died.

A LIST OF MEDICINES USED IN TREATING CATTLE.

The medicines used in the treatment of the diseases of cattle, are
essentially the same as those in vogue for the diseases of the human
being and the horse,--the only difference being in their combination and
the quantities administered.

ABSORBENTS.--Medicines which destroy acidities in the stomach and
bowels; such as chalk, magnesia, etc.

ALTERATIVES.--Medicines which restore the healthy functions of
secretion, by gradually changing the morbid action in an impaired
constitution. Those in most common use are AEthiops mineral, antimony,
rosin, sulphur, etc., which form the principal ingredients in all
condition-powders, and are chiefly useful in diseases of the skin, such
as hide-bound, mange, surfeit, etc.

ALTERATIVE POWDER.--Sulphur pulverized, one pound; black antimony, one
half a pound; nitrate of potassa, four ounces; sulphate of iron, one
half a pound; linseed meal, one pound; mix well; dose, one half an
ounce, night and morning.

ANTACIDS.--Agents which neutralize, by their chemical action, acids in
the stomach; as ammonia, carbonate of potassa, chalk, lime-water,
magnesia, and soda.

ANTHELMINTICS.--Remed
