368 DISEASES OF BREATHING. 



and dry. This cxjndition is soon followed by a watery discharge 

 from these parts. In a few days the discharge becomes yellow, 

 thick, and copious, especially from the nostrils, like what we our- 

 selves experience in the later stages of a cold in the head. There 

 is more or less fever, dulness, and a roughness of coat, with or 

 without shivering fits. Cough is usually present, and may con- 

 tinue for some time after the other symptoms have subsided. 

 Catarrh, generally, runs its course in about a fortnight, although 

 it may induce a prolonged state of bad health in the animal. 



TREATMENT. — Put the horse on bran and linseed mashes, and 

 give freshly-cut grass or lucerne. Allow a constant supply of drink- 

 ing water, and give in it three-quarters of an ounce of nitre daily. 

 Have the stable well ventilated, though free from draughts ; and 

 keep the animal comfortably clothed. Make him, from time to 

 time, inhale steam, either plain or mixed with turpentine, in order 

 to facilitate the discharge from the nostrils. If the cough is 

 troublesome and the breathing difficult, blister the throat with 

 tincture of cantharides. If a milder effect be required, stimulate 

 the part \yith equal quantities of ammonia, turpentine and oil. 

 An electuary of two drachms of camphor and a drachm of bella- 

 donna, made up into a soft mass with a little linseed meal and 

 treacle, may be given every day ; a little at a time being placed 

 between the animal's back teeth, for him to gradually swallow. If 

 the bowels be constipated, administer an enema of warm water, and 

 give, for a day or two, about a pint of linseed oil mixed up in, and 

 divided between, his mashes. 



If, subsequently, there be great debility, the horse may have a 

 couple of quarts of beer a day, and a drachm of sulphate of iron 

 mixed, daily, in his food. 



Cough. 



This is a symptom of various diseases, which, instead of the 

 cough, should be specially treated. 



I have alluded, under the various headings, to the chief kinds 

 of coughs that are, respectively, characteristic of certain com- 

 plaints such as bronchitis, sore throat, pleurisy, "broken wind, and 

 roaring ; so need here discuss only the condition which is popularly 

 called "cough," on account of its exciting cause not being usually 

 apparent to persons uninstructed in veterinary medicine. These 

 coughs may be roughly divided as follows : — 



1. TEETHING COUGH.— Though teething is generally alleged 

 to be a common cause of cough, I have never met with any prac- 

 tical proof of this statement, and consequently can speak only from
