red
unusually stimulating; and the acrid plants of the marshes and low
grounds acquired additional deleterious agency.

"When isolated cases occur, they may generally be attributed to
mismanagement. Exposure to cold, or the drinking of cold water when
overheated with work; too hard work in sultry weather; the use of water
stagnant, impure, or containing any considerable quantity of metallic
salts; the sudden revulsion of some cutaneous eruption; the crowding of
animals into a confined place; too luxuriant and stimulating food
generally; and the mildewed and unwholesome food on which cattle are too
often kept, are fruitful sources of this complaint."

_Treatment._--In the early stage of the disease, give an active purge,
and follow it with ten drops of Fleming's tincture of aconite, four
times daily, for two days; then give drachm doses of the extract of
belladonna; give no food for twenty-four or forty-eight hours, according
to circumstances. Bleeding, if done early, is often beneficial.
Counter-irritants to the belly are also recommended; the best are
mustard, hartshorn, and water, mixed together--or tincture of
cantharides, with one drachm of croton-oil added to every ounce.

EPIZOOeTICS.

Diseases of this class have the same relation to the inferior animals
that epidemic diseases have to man. Of course, they assume a very
pestilential character. Scarcely a year passes away without diseases of
this nature making their appearance in some parts of the world. They
occur at all seasons of the year, but more generally prevail in the
spring and fall. The period of their duration varies from months to
years. They are, at times, mild in their attacks, and yield readily to
proper treatment; at other times, they become painful pestilences,
destroying every thing in their course.

The causes are generally sought for in some peculiar condition of the
atmosphere. The use of the milk and flesh of diseased cattle has
frequently been productive of malignant diseases in the human family.

Silius Italicus describes a fearful epizooetic, which first attacked the
dog, then the feathered biped, then horses, and cattle, and, last of
all, the human being.

"On mules and dogs the infection first began,
And, last, the vengeful arrows fixed in man."

Epizooetics, occurring in rats, cats, dogs, horses, and cattle, which
were followed in the succeeding years by more fearful ones which
attacked the human family, are numerous
