s size. Others also appear until the whole of
the glands are involved; and the extent of the implication renders an
operation, which in the first instance would have been both simple and
safe, so complicated and hazardous as not to be risked. The tumors,
moreover, as they enlarge, by their weight and size, become exposed to
numerous accidents; either they are excoriated by the movements of the
legs, hurt by blows, or lacerated by being dragged along the ground.
Anything that interferes with their integrity seems to change their
character. From having been dormant they start into activity, and the
slightest wound degenerates into a wide-spreading ulcer. When this last
appearance is established, no treatment I know of can effect a cure. If
there be a hope, it lies solely in the skilful use of the knife; but
generally the constitution is so much exhausted, and the disease so firmly
established, that surgery is but a desperate resort.

When taken in time, the situation of the tumor being ascertained, the
skin is divided and the growth dissected out. This is easily done, and it
is seldom that a vessel requiring ligature is divided. The care required
is to spare the skin, no portion of which, unless it should be implicated,
ought to be excised. Neither plaster nor suture will afterwards be wanted.
The bitch would with her teeth remove either; and as the healing process
is established, the integument will contract and unite.

When there is more than a single tumor to take away, or one of large
dimensions to remove, though there may be no important vessels to
ligature, the oozing of blood is sometimes greater than may with safety be
disregarded. In such cases, the application of cold water, or of oil of
turpentine, or the tincture of ergot of rye, or blowing upon the part by
means of a pair of bellows, will be of service, and may each be tried; but
the actual cautery, though held in high esteem by veterinarians, is not
suited to these instances.

After the tumor or tumors are cleanly removed, a course of iodine should
be enforced; and it should be persevered with for several months, nor
given up simply because all present symptoms have disappeared. The
tendency has been exhibited, and the medicine is now employed to prevent
its development for the future; and, by the continued use of the agent, we
hope to accomplish that intention.

SKIN DISEASES.

Every affection of the skin in the dog is termed mange. This is very
