406 FOREIGN BODIES INJURING THE HEART. 



animal had coughed for the first time, eructations still con- 

 tinued. 



Cadaveric lesions. Considerable infiltration of the thorax, 

 abdomen, and dewlap ; blood very black, but did not stain 

 the fingers much ; the lungs were in parts congested ; most of 

 the interlobular cellular tissue infiltrated, in some parts 

 marbled. 



Superior part of the costal pleura sound ; inferiorly on a 

 level with the base of the heart, thickened by false membranes 

 of slight consistence and yellow colour, the diaphragmatic 

 pleura still more so; here they connected it closely with the 

 pericardium, for about seven or eight centimetres. About 

 eight or ten quarts of very thick, yellowish, foetid fluid was 

 effused into the pleural cavity. 



The pericardium was more than tripled in size, and dis- 

 tended by at least three quarts of very thick purulent fluid 

 of a grayish-yellow colour, insupportable gangrenous odour, 

 and containing shreds of false membrane. 



In the pericardium was a sewing-needle, blackened by rust; 

 the sac had acquired walls of more than a centimetre in 

 thickness ; these were hard to cut, and showed three distinct 

 layers; the median one, corresponding to the fibrous pericar- 

 dium, was the thickest and most dense, of a yellowish-white 

 colour; the other two corresponded to the two serous mem- 

 branes which normally cover the above ; they were three or 

 four millimetres thick, having a rough irregular surface and 

 a remarkable earthen-yellow colour; some shreds of false 

 membrane were attached to them. 



The heart was a little hypertrophied, and being completely 

 covered by false membrane, was in physical aspect exactly like 

 the pericardium ; its section showed three 'layers, the outer, 

 the thinnest, as of false membrane; the median, like the analo- 

 gous one in the pericardium, bearing an aspect of rancid lard,
