DISEASES OF THE RESPIK-ATORY ORGANS. 501 



to be highly albuminous, and charged with shreds of solid deposit. 

 Both lungs were found adhering firmly to the pleura, and in at- 

 tempting to pass the hands round the large posterior lobes, we 

 found it extremely difficult to detach the diseased portions from 

 the ribs. 



The false membranes were found adhering closely to the pleura 

 covering the lung, and to the pulmonary substance itself; and the 

 former — the pleura — mottled in color, with more or less marked 

 papillary or warty looking eminences. 



This development showed that the disease had been one of 

 unusual virulence. 



There was considerable fluid around the lungs, the quantity of 

 which we could not estimate, as it was found impossible to sepa- 

 rate it from' the shreds of lymph and false membrane in which it 

 was held. Examination revealed a large quantity of pus cells, 

 and a portion of the fluid placed in a tumbler partially gelatinized 

 on prolonged exposure to the air. The lower portion of the right 

 lung was gangrenous and abscesses were found therein, which 

 gave out a highly offensive odor on opening. The left lung had a 

 small gangrenous spot upon the inner posterior portion of the apex. 



On removing the lungs, both were found to present a badly 

 diseased appearance, the right being the worst. The collapsed 

 portions with the normal pink color, denoting healthy tissue, were 

 extremely small, showing the animal possessed more than ordinary 

 vitality to have existed with so little means of aeration of blood, as 

 long as circumstances indicated she did. On cutting into the hard 

 and mottled diseased portions, a very peculiar marbled appearance 

 was presented : the substance of the lobules being solid and of a 

 darkened color, while the tissue between the lobes was yellowish, 

 more or less dotted with red points. The gradation from healthy 

 to diseased tissue was very marked, showing first, lobules slightly 

 infiltrated with semi-liquid serum, followed by those more thick- 

 ened, and of a lighter red color showing the moic recent deposits, 

 .and lastly the thoroughly consolidated portions. Now we find 

 the lung substance entirely broken down, the more solid portions 

 detached and imbedded in the cavities of the diseased tissue, acting 

 as foreign bodies, and hastening gangrene. The adimssion of air
