gth you possess is capable of sending the animal; for
the instant the dog is loose, it will begin shaking its head, and, as the
canker-wash I employ contains lead, wherever a drop falls, a white mark or
spot, as the liquid dries, will be left behind.

Youatt speaks of the liquor plumbi as a dangerous agent to the dog, and
advises for canker that a scruple be mixed with an ounce of water; but in
opposition to that esteemed author's recommendation, I have employed the
liquor plumbi pure, with the best effect, in extreme cases; though, in
ordinary disease, the above is sufficiently strong; and in medicine it is
a maxim that a sufficiency is enough.

I give to the animal, as a general rule, no medicine to take; but
invariably recommend the dog to be kept on vegetable diet; for, inasmuch
as meat is the sole cause of the disorder, however potent may be the drugs
employed for the cure, it is imperative for its eradication that the cause
be removed.

Sometimes, in consequence of the violent shaking of the head, serous
abscesses of considerable size form inside the flaps of the ears. This
mostly happens with large dogs, and the abscesses are hot and soft, being
excessively tender. The animal does not like them to be touched, or even
looked at, but is frequently shaking the head, and howling or whining
afterwards.

The remedy in these cases is equally simple and efficient. The person who
undertakes to remedy the evil, first, by way of precaution, tapes the
animal; that is, he forms a temporary muzzle, by binding a piece of tape
thrice firmly round the creature's mouth. He then places the dog between
his knees, and turning up the ear, with a small lancet makes quickly an
opening in what then is the superior part of the sac in the inverted ear.
This is necessary, because, if the opening were made inferiorly, all the
fluid would escape, and the side of the emptied sac would collapse. If the
point of the knife even could be introduced into an incision made upon the
lower part of the ear, it would not be so easy to cut speedily from below
upward, as to push the blade from above downwards. Well, the opening being
made with the lancet, a little fluid escapes; but no pressure being put on
the sac, the major portion is retained. The operator then takes a straight
probe-pointed bistoury, and having introduced it into the or
