ith marked benefit
to the animal. The operation is tedious, but it repays us for the time it
occupies. Towards the conclusion the stream is frequently interrupted. It
stops, then recommences; ceases, and then begins again; and the last
portions are often ejected with a force which the first did not display. A
little straining may attend the closing of the operation. For this the
operator must be prepared, and immediately withdraw the catheter; lest the
bladder, energetically contracting upon it, should cause the point to
pierce the sides of the viscus. The instrument is no longer required when
straining is excited; for then the contractive function has been resumed,
and nature will subsequently perform her office without assistance.

The bladder that has been relieved, may require the care of the surgeon a
second time; but no officiousness should be indulged in that respect. Let
the necessity be present before the operation is resorted to; and the need
for its adoption can be so accurately ascertained, that there is no excuse
whatever for needless interference. The operation is attended with no
immediate danger or subsequent ill consequences, that I am aware of; but
it is particularly recommended by the fact, that in the dog it is not
accompanied with that pain, which in man usually provokes exclamation,
sometimes causes fainting, and not unfrequently induces irritability of
the membrane lining the canal.

The testicles are occasionally the sources of annoyance to the proprietor.
In one instance a high-bred dog was sold, the person who bought the animal
making the purchase with a view to breeding from it. Disappointment
followed, for no sexual desire could be excited; and as a stock-dog, the
beast was useless. An examination was then made, and the scrotum was
discovered to contain no glands.

A most infamous fraud was now accused against him who had sold the dog;
and as dog-dealers are not so respectable, and are almost as little
credited as horse-dealers, any charge imputing dishonesty required no
evidence to substantiate it. An infamous villain was convicted of having
castrated the dog before he parted with it, in order that a valuable
strain might not be rendered common. This same dog was brought to me. I
could detect no testicles, and I could perceive no cicatrix. The body was
fat and the disposition sluggish, but the frame well developed. It was
possible the scar, if the operation had been performed early, should
