CHRONIC EMPHYSEMA OF THE LUNGS. _ 623 



back, sides, — in fact all over the body. The crepitations may 

 not be very pronounced at first, probably from the fact that 

 the emphysema is deep-seated, and mechanically pushing the 

 superimposed tissue in the outward direction ; but in a very 

 short time the crackling sounds emitted on pressing the parts 

 leave no doubt as to its true nature. The bowels are generally 

 constipated, and some recover when free action of the bowels 

 has been established. Some of Mr. Snarry's cases occurred 

 prior, others subsequent, to parturition. In none of the cases 

 was there any great elevation of temperature, 103° F, being the 

 highest. 



TREATMENT. 



'No permanent benefit can be expected from any treatment. 

 Much relief may, however, be afforded by careful dieting, keeping 

 the bowels regular, and when the paroxysms of dyspnoea are 

 very great, by the administration of sulphuric ether, chloral 

 hydrate, or the bromide of ammonium. A horse thick in the 

 wind, or sufferiDg from chronic cough, is an unsound animal.
