_Gadfly Bites._--Often very annoying. May be prevented by washing legs and flanks with a strong tea of green elder bark.
_Galls_--from saddle.--Best prevented by leaving the saddle in place for twenty minutes after loosening the girths. When occurring, however, should receive prompt attention, as they are very tedious if neglected. Examine the back carefully after the first ride on a new horse, and also before putting on the saddle the next day.
GLANDERS.--A disgusting, contagious, and incurable disease, the chief symptom of which is a discharge from one nostril, at first transparent, then slightly sticky, then thick and yellow. As it is highly contagious to human beings, in whom it is equally dreadful and always fatal, _a glandered horse should be instantly killed, as the law requires_. It is well to avoid all horses having any discharge, however slight, from the nose. Glanders may be caught from "farcy," and _vice versa_.
GRAPES.--A filthy and incurable disease of heels and pastern, caused by gross neglect. It is the last stage of "grease."
GREASE.--An aggravated form of "chapped heels," accompanied by swelling, fever and a serous discharge. Wash clean frequently, and anoint with Dalley's salve.
HEART DISEASE.--May be detected by auscultation. Incurable. Ends in sudden death.
_Hide-bound._--The skin appears too tight, and as if fast to the ribs. It is caused by a disordered stomach, and requires nourishing food.
_Inflammation of Bowels._--The pain is continuous, and the horse is careful not actually to strike his belly with his feet. Requires, of course, very different treatment from colic, but an injection should be the first thing done.
_Interfering._--Striking the fetlock-joint with the foot. Caused sometimes by weakness and fatigue, but usually by bad shoeing, and a good blacksmith is the best adviser.
_Lampas._--A swelling of the gums, relieved by lancing.
KNEE-SPRUNG.--Incurable. Result of overwork.
KNUCKLED.--Same as "set over." A condition of the fetlock-joint corresponding to that of the "sprung" knee.
LAMINITIS.--The scientific name of "founder."
MAD STAGGERS.--Violent insanity, caused by inflammation of the brain. The last stage sometimes of sleepy staggers. Incurable.
