164 DISEASES OF THE LUNGS. 



the parenchyma; but, what seemed very remarkable, it 

 neither increased the number of the vesicles, nor enlarged those 

 already existing. After inflation, the entire lung became 

 still paler, and crackled more when squeezed with the hand. 

 This Mr. Cherry thought arose from the rupture of more 

 cells; I had, however, and still have, my doubts on that 

 point. The bronchial and tracheal membranes, though of 

 their natural colour, were much thickened. The membrane 

 covering the arytenoid cartilages was likewise thickened, and 

 studded with little hard papillary eminences. There was 

 no alteration in the form of the trachea. 



Mr. Cherry has since examined another very decided 

 case of broken-wind, destroyed at the request of the owner 

 on Mr. Cherry^s own premises, in which he found perfectly 

 analogous appearances. 



Feb. 14/A, 1843, H. P. Bks.— Col. Cavendish ordered 

 his black mare to be destroyed, on account of incurable 

 lameness in her feet, particularly in the off fore one. She 

 was, in fact, foundered from navicular disease. She had 

 had a cough for several years (being now above 16 years old); 

 and the last time I examined her, on account of her lame- 

 ness, I, hearing her cough, pronounced hef to be going 

 broken-winded ; since which, although her cough leads to that 

 opinion, there has been no decided movements of the flanks, 

 to warrant any conclusion. About 5 o'clock this afternoon 

 she was shot. Her lungs were preserved, and next morning 

 examined. They had not collapsed like healthy lungs; but 

 presented the pale pink hue, and had the true emphyse- 

 matous character of broken-winded lungs; though the 

 emphysema, which was greatest in the anterior lobuli, and 

 more in the near than in the off-lung, did not prevail to 

 that extent which in more advanced or confirmed cases it is 

 found to do. There was some appearance of thickening, 

 with opacity and whiteness, about the membrane lining 

 the trachea and bronchial tubes; but it was not in the 

 latter of a very decided character. The larynx was not 

 preserved. 



In the foregoing pathological accounts, two morbid
