for years; sometimes it will even be continued with no 

 obvious injury for his whole life. 



The Treatment of " chronic cough " must depend on our 

 view of its causes and consequences. When it appears to 

 arise from a want of mucous secretion, give expectorants 

 which excite such secretion (A) or (C) Expectorants (Horse 

 Medicines). When a redundancy of the mucous secretion 

 is apparent, tonics are required. (See Tonics and Stimu- 

 lants.) When the secretion is acrid, try a Demulcent. The 

 cough, which is the effect of an irritable state of the parts, 

 is sometimes relieved by stimulating the throat externally, 

 and by giving internally opium, with bitter tonics. 



When worms in any large numbers are present in the 

 stomach or intestines, a continued cough generally exists, 

 with irregular appetite and unthrifty coat, stools fetid and 

 slimy, at one time loose, and at another hard and dry ; for 

 which turn to the head under which those parasites are 

 specially treated of. In all chronic coughs, the best effects 

 sometimes follow from feeding with carrots. Turnips, 

 parsnips, beet, and potatoes ma}^ be beneficially used where 

 carrots cannot be got ; and a mash with bran and linseed, 

 or malt, may be occasionally given. Try the following 

 every morning, made into a ball with honey : 



Powdered ipecacuanha ... J drachm. 



Camphor 2 drachms. 



Extract of belladonna ... 1 scruple. 



Thick Wind. — This is also a consequence of either acute 

 or chronic pulmonary inflammation. In some instances it 

 is the immediate coQsequence of violent or long-continued 

 exercise, and particularly if the exercise be taken upon a 

 distended stomach and bowels, or after full drinking; or it 

 may be brought on by the application of cold. It is often 

 connected with a plethoric state, and is therefore very 

 common among pampered animals and gross feeders, and 

 more particularly in low-bred and thick-set horses. The 

 post-mortem examinations of such cases exhibit, in some 

 instances, a slight hepatisation of lung, the consequence of 

 repeated congestions ; in others, the minute bronchial cells 

 are filled with adhesive matter, or the general substance 

 may be pervaded with minute granulations of a bluish 

 colour^
