BROKEN-WIND. 165 



states demand our particular attention : these are, emphysema 

 of the lungSy and alteration of the membrane lining the air- 

 passages. It is the former, however, which has — perhaps 

 from its presence being more constant and uniform— in an 

 especial degree attracted the attention of veterinarians^ of 

 our own country in particular ; and to that degree that some 

 — among whom stood prominent the late Professor Coleman 

 — have unhesitatingly asserted, that emphysematous lung 

 constituted the pathology of broken-wind. In this advanced 

 state of science, however, we dare not hasten to such a con- 

 clusion before we have examined and well weighed in our 

 minds some facts which appear to militate against this 

 theory. That broken-wind, or a disorder undistinguishable 

 from it, may arise, and yet 



Emphysema not present, we have unquestionable 

 authority for affirming : in France, we have Godine, 

 Volpi, Rodet, D^Arboval, and Delafond ; in England, 

 Professors Sewell and Dick, Messrs. W. Smith and Hallen; 

 and we may now add, Mr. Gloag, Veterinary Surgeon, 

 11th Hussars, who, in 1851, committed to paper some 

 admirable ^' Thoughts^^ on the subject, which will be 

 found in vol. xxv of ' The Veterinarian.^ Even 

 Delafond, who is the greatest French advocate for the 

 emphysematous theory, avows that, out of fifty-four broken- 

 winded horses which he examined, he found forty-five 

 with emphysema, including dilatation of the air-cells of 

 the lungs; whence he concludes that only about thy^ee 

 fourths of the cases of broken-wind are of this nature, 

 leaving one fourth to arise from other causes. Although 

 the fact, that symptoms of broken- wind may issue from 

 other pathological conditions appears irresistible, still are we 

 left in a position fearlessly to pronounce, that the ordinary 

 and by far the most uniform lesion present with the disease, 

 is emphysema. 



Does emphysema ever exist without broken-wind? — 

 Yes, of one description, but not of the other. For em- 

 physema of the lungs, which was first observed by Dr. Baillie, 

 but afterwards more fully investigated and explained by
