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 
severe, 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 may be fluid or solid, as for instance water, food, or other 
matters which perchance find their way into the air tubes. 
oo. In cases of bronchitis, the horse should be warmly clad and placed ina 
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 
of 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 tothe 
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 very persistent nature when once established. 
-T 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 of camphor, one drachm of nitre, one drachm of i ipecacuanha, and one drachm 
“of sq “squills may be made up to eight _drachms, and given three times daily. 
‘Later on tonics are required’ One drachm of powdered nux vomi 
__drachms. ‘of. carbonate of ammonium, and two drachms of citrate of iron and 
\_ammonium, ‘made “up into.a ball of of eight drachins with gentian and treacle, 
; may. then be | given twice or thr e times daily. Chronic “bronchitis is an 
exhausting disease, and unless carefully and judiciously managed, not 
_ uncommonly passes from bad. to worse, until the animal al loses its appetite, 
and becomes emaciated and incapable of work,
