ASTHMA. BROKEN WIND. HEAVES. DYSPNCEA'. 

 PULMONARY EMPHYSEMA. 



Definition, neurotic affection with digestive and respiratory disorders. 

 Causes, no racial exemption, disease largely co-extensive with leafy hay 

 from clover, alfalfa and other leguminous plants, musty hay, cryptogams, 

 overloading the stomach, active work on a full stomach, overdriving, bron- 

 chitis, chronic bronchitis, emphysema. Nature, a neurotic affection, start- 

 ing with derangement of some part of the vagus, dilatation of the right 

 heart, congestion of the bronchioles. Symptoms, double expiratory action, 

 flatulence, weak, husky, wheezing cough, glairy, grayish nasal discharge, 

 wheezing, increased resonance along the margins of the lungs, sibilant 

 r41e, heart's impulse strong, even felt on right side, aggravation with over- 

 loaded stomach, costiveness or muggy atmosphere, improvement on laxa- 

 tive (green) food. Treatment, succulent green food, natural pastures, re- 

 lieve any abnormal state of lungs or bowels, pure air, heart tonic, diet, 

 arsenic, special diagnosis, guard against masking of symptoms by narcotics, 

 privation of water, shot, lard, recto-vaginal fistula, diagnostic signs, dilated 

 nostrils, auscultation and percussion signs of emphysema, relapse under 

 hay and water. 



Definition. A chronic affection of the equine species, mani- 

 fested by a hurried, wheezy breathing, greatly aggravated by 

 close, muggy weather, a full stomach, certain kinds of diet, or 

 by exercise ; by a double lifting of the flank with each expira- 

 tion ; by a small, weak, dry cough, often occurring in paroxysms 

 and easily excited by a drink of cold water, exposure to cold air 

 or a fibrous quality of the food ; and lastly, by a marked disorder of 

 the digestive organs. 



Causes. This disease is essentially the result of faulty feeding 

 and working, though pre-existing diseases of the air passages and 

 sudden violent muscular efforts no doubt occasionally contribute to 

 its development. 



It has been alleged that some races of horses are exempt from 

 this disease. Among these the Arabian, Persian, Barb, Spanish 

 and Portugese are especially named, but their immunity in all prob- 

 ability depends on the feeding and management rather than on any 

 peculiarity of breed. The countries where these horses are met 

 with are not subject to a prolonged winter but yield green food 

 throughout the greater part of the year, and it is a notorious fact
