ease--known by the other names
of black quarter, and joint murrain--is quite common among young cattle,
and is generally fatal in its termination. There is little or no warning
of its approach. The first animals in a herd to be attacked are
generally those in a full, plethoric condition.

_Symptoms._--The joints suddenly become swollen, and so painful as to
produce severe lameness, particularly in the hind parts. General
irritative fever exists in the system, attended with great tenderness of
the loins; the head is poked out; eyes red and bulging; the roots of the
horns, as well as the breath, are hot; the muzzle dry, and nostrils
expanded; pulse rises to seventy or eighty, full and hard; respiration
is hurried; the animal is constantly moaning, and appears to be
unconscious of surrounding objects; the swelling of the limbs extends to
the shoulder and haunch; the animal totters, falls and dies in from
twelve to twenty-four hours.

_Treatment._--Early bleeding is requisite here, to be followed by active
purgatives; after which, give one of the following powders every half
hour: nitrate of potassa, two ounces; tartrate of antimony and
pulverized digitalis, of each one and a half drachms; mix, and divide
into eight powders. These should not be renewed. Cold linseed tea should
be freely given.

RABIES.

Hydrophobia in cattle is the result of the bite of a rabid dog, from
which bite no animal escapes. The effects produced by the wound made by
the teeth of such an animal, after the virus is once absorbed into the
circulation of the blood, are so poisonous that all treatment is
useless. The proper remedies must be instantly applied to prevent this
absorption, or the case is utterly hopeless. Among men, nine out of
every ten bitten by rabid dogs escape the terrible effects resulting
from this dreadful disorder, without resorting to any applications to
prevent it. It is a well-established fact, that men, when bitten by
dogs, are generally wounded in some part protected by their clothing,
which guards them from the deleterious effects of the saliva which
covers the teeth, and which, at such times, is deadly poison. The teeth,
in passing through the clothing, are wiped clean, so that the virus is
not introduced into the blood; hence the comparatively few cases of
rabies occurring in man. When, however, the wound is made upon an
exposed surface, as the flesh of the hand, or of the face, this fatal
disease is developed in spi
