mucus. The discharge escapes to some extent through the nose, but the 

 greater part passes into the mouth and is swallowed. In the later stages, 

 however, a profuse discharge escapes through the nostrils. The cough 

 becomes more violent and frequent than at first, but gradually becomes less 

 se\ere, and finally disappears. Bronchitis of the larger tubes, ends in most 

 instances in perfect recovery ; but when affecting the small tubes and vesicles 

 of the lung, it is always dangerous, and requires great care. Mechanical 

 bronchitis is induced by the inhalation of some irritant. The irritating agent 

 may be gaseous, as for instance smoke from a burning building or acrid 

 fumes ; or it ma)' be fluid or solid, as for instance water, food, or other 

 matters which perchance find their way into the air tubes. 



In cases of bronchitis, the horse should be warmly clad and placed in a 

 well-ventilated loose box, and the diet should be liberal, nutritious, and 

 laxative. The animal should be made to inhale hot water vapour, which may 

 be medicated by the addition of two drachms of carbolic acid to each quart 

 x^)f hot water. If there be any sore throat, stimulating embrocations, as for 

 instance compound liniment of camphor, should be applied externally. If 

 the bowels are inactive, enemas should be administered, and if they still 

 -continue constipated, three or four drachms of aloes, or three quarters 

 of a pint of linseed oil may be given. A draught made up of four ounces 

 of solution of acetate of ammonium, one ounce of nitric ether, one drachm of 

 camphor, and half an ounce of tincture of squills may be given three times 

 daily with half a pint of water. In cases where the small tubes are much 

 affected, blisters or stimulating liniments may be applied with advantage to 

 the sides of the chest. In the later stages tonic medicines are often required. 



Chronic bronchitis is met with in the horse either as a sequel to the 

 acute form, or as an independent disease. It differs from the acute form in 

 its slower progress, and in its symptoms being less severe; and is characterised 

 by a persistent hard and sonorous cough, and by the absence of febrile 

 manifestations. In many instances, this disease causes gradual loss of flesh, 

 diminution of appetite, and general debility. When it occurs as an 

 independent affection, it is generally gradual in its onset and development, 

 and of a veiy persistent nature when once established. 



The diet in this complaint should be liberal and nutritious. Rest is not 

 necessary, though severe] exertion should be prohibited. The remedies 

 recommended in the acute form may be with advantage tried in the more 

 persistent and chronic form of the malady. A ball containing one drachm 

 of camphor, one drachm of nitre, one drachm of ipecacuanha, and one drachm 

 of squills may be made up to eight drachms, and given three times daily. 

 Later on tonics are required. One drachm of powdered nux \ omica, two 

 drachms of carbonate of ammonium, and two drachms of citrate of iron and 

 ammonium, made up into a ball of eight drachms with gentian and treacle, 

 may then be given twice or three times daily. Chronic bronchitis is an 

 exhausting disease, and unless carefully and judiciously managed, not 

 uncommonly passes from bad to worse, until the animal loses its appetite, 

 and becomes emaciated and incapable of work.
