uffering thus occasioned was
unnecessary. Canker without the ear cannot be established unless canker
within the ear, in the first instance, exists. It may not be violent; it
may be present only in an incipient stage, and never get beyond it; but in
this state it is sufficient to annoy the animal, and make it shake its
head. Doing this, however, it does enough to mislead the practitioner, and
cause the death of the unfortunate animal.

[Illustration: DOG WITH A CANKER CAP ON.]

When a dog is brought with canker in the flap, the first thing I order is
a calico cap, to keep the animal from shaking the ear. I then give the
person accompanying the creature a box of the mercurial and camphor
ointment, ordering it to be well applied to the external ear thrice daily,
with the intention of cooling the part. I do nothing absolutely to heal
the ulcers beyond keeping the part from being shaken; for I have not yet
met with a case in which the cartilage has been positively involved,
however much authors may write about such a texture having suffered. I
direct my chief attention to the healing of the internal ear, from which I
trace all the evil to have sprung. For this purpose I give a bottle of the
canker-wash, described a little further on, ordering it to be applied
thrice daily, and rest contented as to the result.

With regard to internal canker, how virulent was the disorder, and to what
lengths it used to progress, may be imagined from reading Blaine and
Youatt; both of whom speak with terror of its effects, advising the use of
agents for the recommendation of which I cannot account, excepting by the
supposition that they were selected under the influence of fear. Most of
the solutions advised are painful; but how far they were effective we may
conjecture from the descriptions they have left us of the disease. They
tell us that, as the disorder proceeds, it eats into the brain; either
causing the dog to be destroyed, or driving it phrenetic. The poor animal,
we are informed, leans the head upon the fore-feet, the diseased ear being
pressed downwards, and continually utters a low moan, which at length
rises into one prolonged howl. Of all this I know nothing; but I remember
at college, when going the rounds with the Professor Simonds, on a Sunday
morning, hearing one of those huge howls which are uttered by large dogs
when enduring excessive torture. On my asking whence the sound proceeded,
I was coolly informed by my teacher t
