INTERNAL ORGANS. 



dead animal, by ruptaring one or more of 

 the small branches of the windpipe, and then 

 blovvinor into the lunc^s. The air which is 

 forced in will then escape through the rup- 

 tured parts, and be diffused in the cellular 

 membrane*, so as to make the lungs appear 

 mucii larger than they were berore. When 

 the air is at lencrth forced to the surface of the 



o 



lungs, it will be prevented from escaping by

 The cellular .aeiubrane is Composed ot ceiis o. vd4io>.s siics, 

 wliich comminiicate treely with euch orher, so that il a Llowprpe 

 be put uito one of the cehs, and air iorced throagfi it, a!l the 

 neigliboufing parts will be blown up to a considerable size. A 

 familiar example Oi this is the practice among butchers ot blowing 

 up the cellular membrane ot a shoulder ot veal. It sometimes 

 happens in the case ot a fractured rib, that one end of the bone 

 is forced into the lungs, so as to wound the branches ot the 

 windpipe and the pleura; the air which is inspired whi then 

 escape; and, as the wound communicates with the cellular 

 membrane between the muscles of the ribs, the air gradually 

 diffuses itself through ail the contiguous parts; and we have 

 sometimes seen the Avhole body, and even the cellular mem- 

 brane about the eye, inflated from this cause.
