34 THE DISEASES OF IIORSES, 



has its peculiarity, which to the experienced and attentive gives pretty 

 sure indication of the seat of the disease. Cough is produced by worms 

 in the intestines, in which cases the lungs act sympathetically with the 

 irritation caused by these parasites ; if worms be the cause, a variable 

 appetite, and a harsh, dirty staring coat will also exist as additional 

 symptoms, and then, after one or two mashes, the following vermifuge 

 might with advantage be given as a drench : 



Vermifuge. — 2oz. of spirit of turpentine, loz. of laudanum, 1| pints of lin- 

 seed oil ; this should be followed by linseed toa or oatmeal gruel. Cough is 

 also a symptom of various disease3 of the lungs and air passages from the 

 slight irritation that exists often in the lining membrane of the outer 

 passages, to bronchitis and inflammation of the lungs; ib accompanies 

 thick and broken wind, is caused by glanders— a disease seated near to 

 and affecting the air passages— and is also often present in diseases of the 

 stomach and bowels. 



Some of these diseases on their disappearance leave behind them such 

 an over-sensitiveness and irritability of tho air-pipes, that the horse is 

 ever after liable to a cough more or less severe, which is brought on with 

 any change of temperature, as being taken from the stable to the outer 

 air, changing from a warm stable to a colder one, or vice versa, and 

 frequently after drinking. 



Although a horse with one of those irritating chronic coughs may go 

 on for years doing useful work, he is predisposed to the more dan- 

 gerous forms of disease of the respiratory organs, and must on that 

 account receive special care, and be closely watched, and any increase in 

 the severity of the affection should not pass unheeded ; much may be 

 done to alleviate suffeiing and prevent serious consequences by a wise 

 and prudent attention to the proper feeding of the horse and his comfort 

 in tho stable. An ill- ventilated, close, filthy stable is in itself sufficient 

 to set up a cough ; and an animal whose wind pipes are exceptionally 

 sensitive should not have dry food and chaff. Dusty hay should be care- 

 fully avoided, and all corn and cut hay or straw should bo damped ; 

 and in cases where tho stomach is involved, the use of green food or 

 roots in addition will be an advantage. When the cough i3 unusually 

 severe the following ball may be occasionally given, but not too often, as 

 the medicines are powerful and not to be made too free with. 



Cough Ball.— Powdered digitalis 20 grains, tartar emetic Idraahm, nitre 

 2 drachms, tar ^oz., linseed meal to form a ball. 



An old-fashioned demulcent medicine of great use in allaying the irrita- 

 bility in these cases is the marsh mallow, and benefit will often be found to 

 arise from giving it with linseed in a mash two or three times a week. 



Marsh Mallow Demulcent.— Take 4oz. or 8oz. of the root, according as 

 it is dry or fresh, and boil it well over a slow fire in a gallon of water, 

 and take the root out by straining, and, adding more water, boil in it 

 half a pint of linseed, and mix the lot in a bran mash. 



If the cough is supposed to be connected with disordered stomach, it
