Sometimes on very moderate exercise, horses sweat to excess. It is often the result of weakness, poor food or some internal condition. Give J.K., a few times, in doses of fifteen drops, morning and night. Tumors, Swellings Any unusual or morbid growth or enlargement may be termed a tumor, and when one is found upon any part of an animal, care should be taken to ascertain, if possible, its nature and cause. They are variously named, according to their locality and the nature of their contents. Sometimes they are globular or conical, or again flattened, or again pedunculated (having a neck). Some are quite firm and hard, others spongy, and others contain fluid. Encysted Tumors (so called because the enlargement is closed in a sack) are frequent, more or less round, movable beneath the skin, painless, and sometimes attain to a considerable size. They are the result of some internal cause not easily defined. TREATMENT.—In all cases where a tumor or swelling is hot or painful, give A.A., every two, four or six hours, in doses of fifteen drops, according to the urgency of the case. Keep the animals on low diet and thus seek to disperse it. If caused by external pressure or injury, annoint the part frequently with VETERINARY OIL. If the tumor, notwithstanding the treatment, has softened, grows whitish at some point, painful and smaller, open it, then treat it as an ulcer, giving I.I., morning and night. In case of _cold tumors_ or hot tumors, after the heat has been reduced, simply give I.I., at night, or noon and night, and the J.K., in the morning, in doses of fifteen drops, until the tumor is dispersed or the condition favoring the production is destroyed. Encysted and fatty tumors will generally have to be taken out by the knife and the opening annointed with VETERINARY OIL and again neatly brought together to prevent a scar. Warts Warts are so well known as to require no description. Certain horses and young animals are most subject to them. They vary in size and appearance, are smooth or shaggy, pedunculated or have a large base and some are soft, moist or spongy. They sometimes arise after chafing or an injury, but depend essentially upon an internal cause. TREATMENT.—Give I.I. in doses of fifteen drops, every two or three days for a few weeks, this should cause their entire disappearance. Apply also daily the VETERINARY OIL, scraping off the rough outside of the wart with the thumb nail before or while applying the OIL. CHAPTER II.—PART I. MECHANICAL INJURIES AND WOUNDS The treatment of injuries and wounds is a branch of Veterinary Surgery of the utmost importance to the owners of horses, for accidents are of every day occurrence. We shall, however, not be able to devote so much space to the subject as some would deem desirable.
