52 THE DISEASES OP HORSES, 



they get hot very quickly. If the heels have cracked, and there is much 

 of the offensive discharge, apply very large poultices, changing them as 

 soon as they get at all cold, and dress the legs with the following between 

 the changes : 



Lotion for Cracked Heels : Take chloride of zinc two drachms, glycerine 

 two ounces, tincture of arnica loz., tincture of myrrh loz., water to make 

 1| pints. 



In the chronic stages caustics or the firing iron must be resorted to, and 

 when the granulations above referred to have formed, they have to be 

 removed by the knife, but these are operations requiring the advice and 

 assistance of the veterinary surgnon. 



When grease appears in a horse in good condition, he should at once 

 have a dose of physic— of course having been first prepared by mashes — 

 also loz. of nitre in his mash. Daring grease the horse should not be 

 worked at all if the case is severe, but gentle exercise is always beneficial. 

 The food should be good, but not of a heating nature : Old beans and good 

 heavy oats, but with these carrots, and clover in season. On recovery the 

 horse should have a course of tonics— the tonic powders (p. 53) will 

 answer very well, adding to each dose |oz. of powdered resin and |oz. 

 of nitre. Or the following prescribed by Mayhew may bo substituted for 

 the tonic powders : 



Tonic Draught: Take liquor arsenicalis |oz., tincture of muriate of iron 

 6 drachms, strong ale or stout 1 pint, to be given night and morning. 



Grease, Molten.— See Molten Grease. 



Gripes.— See Colic. 



Gullion— See Colic.

Heart Disease. — This is quite incurable, and, moreover, its existenca 

 is most difficult to determine, and but few outside the profession are able 

 to decide with any certainty whether the horse is or is not under its 

 influence. Should there be any reason to suspect its presence from the 

 haggard and constantly anxious look of the horse, and from any irregularity 

 or unusual action of the heart when carefully listened to by placing the 

 ear against it on the lower part of the chest on the left side, it will be well 

 to have a veterinary surgeon to confirm or remove doubts. As death from 

 this disease is always sudden, and most likely to occur when the horso 

 i3 undergoing great exertion, as when ridden or driven fast, there is great 

 danger of accidents arising ; therefore, when assured that the disease is 

 established, there being no certain symptoms of immediate death, but 

 which last invariably occurs as a surprise, it is better either to destroy 

 life or keep the animal to slow and easy work, by which human life would 

 not be subjected to danger.
