BEOKEN WIND. 143 



Very slow work may be performed without additional 

 inconvenience, but I have seen the effort of drawing 

 heavy weights at a slow pace make the horse stagger 

 and fall in a terrible state of distress. 



Much has been said of the efficacy of arsenic, in 

 doses of 12 grains per day, given for three weeks 

 or a month ; but this must depend on the cause of 

 broken wind, for neither arsenic nor any other drug- 

 can have the power of creating or uniting the air-cells 

 of the lungs. 



THICK WIND OR HIGH BLOWING. 



Thick wind generally succeeds an attack on the 

 bronchial tubes or lungs, which has left a thickening 

 of the membranes, thereby contracting the space or 

 dimensions of the bronchial tubes. 



It is easily perceived by an experienced horseman 

 through the horse blowing freely without sufficient 

 reason, — i.e. when he is not undergoing violent exertion, 

 is not fat, and has not been eating or drinking largely 

 immediately before leaving the stable. It is most 

 commonly met with in under-bred animals of very full 

 habit. The symptoms are utterly unlike those atten- 

 dant on broken wind, the inspirations and expirations 

 being similar, but very much accelerated. The treat- 

 ment, however, should be similar to that recommended 

 for broken wind, avoiding overloading the stomach at 

 any time, and more especially previous to exertion.
