INFLAMMATION. 



presence establish an intramuscular abscess. I have observed 

 this result after amputation of the tongue, for cancer, with the 

 galvano-cautery. 



The cicatrix may, under certain conditions, become trans- 

 formed into bone; and regular bone-plates are sometimes met 

 with in muscle-tissue, which, for a long period of time, was 

 exposed to irritation. 



If, from the very beginning, the inflammatory process is con- 

 fined to the perimysium, a hyperplasia of connective tissue will 



ensue, which is often mistaken 

 for genuine hyperplasia of the 

 muscle-tissue itself. 



In trichinosis, one of the re- 

 sults of the plastic inflamma- 

 tion is the formation of a hya- 

 line capsule around the parasite, 

 provided that the life of the 

 patient is sufficiently prolonged 

 for such a comparatively favor- 

 able termination. How the cap- 

 r sule is formed I cannot say from 

 direct observation. In old cases 

 of trichinosis we find in the mid- 

 dle of the capsule one, sometimes 

 two, worms, coiled up with the 

 well-known two and a half turns, 

 shriveled and evidently saturat- 

 ed with lime-salts. (See Fig. 

 171.) 



The space between the tri- 

 china and its capsule is filled 

 with a granular deposit of lime- 

 salts. Such depositions are fre- 

 quently met with at the poles of 

 the capsule, and sometimes they 

 have a peculiar stratified appear- 

 ance. In the vicinity of an en- 

 cysted trichina we always find 

 cicatricial fibrous connective 

 tissue replacing the muscle fibers which were destroyed by the 

 former inflammatory process, and the cicatrix, as a rule, con- 

 tains a varying number of fat-globules.
