4 THE CANADIAN HOESB 



to be united — inflammation is set up, lymph is thrown out 

 around the fractured ends, small capillary vessels soon shoot 

 into the coagula, from which bony particles are deposited ; 

 and thus by a process of inflammation the continuity of the 

 parts is restored. Inflammation is often made use of to cure 

 diseases and remove callous enlargements. Thus, when a 

 thin opaque film is left on the eye, from a blow or other- 

 wise, a stimulating wash is injected to set up inflammation, to 

 cause blood-vessels to shoot into it, and remove it by absorp- 

 tion. We blister callous enlargements for the same pur- 

 pose. It will thus be seen that, in many cases, inflammation 

 becomes a remedy instead of a disease, and is in all cases a 

 necessary and natural process for the repair of an injury. 



When a part presents the appearance of inflammation, 

 becoming red, hot, tender, and swollen ; and after a time 

 these appearances subside, without producing any alteration 

 in the structure or functions of a part, it is said to have ter- 

 minated in Resolution. When two cut surfaces are brought 

 together, and exudation takes place, and the surfaces are 

 united, as in the healing of a wound by the first intention, 

 it is called Adhesion. When an inflammatory tumour, as 

 that of Strangles, or " Horse Distemper," — at first hard, hot, 

 and painful, goes on, softens in the middle, points, and 

 bursts, discharging a yellowish, creamy fluid, called pus, — it 

 is said to terminate in Suppuration. 



When a part is tardy in heaHng, and presents an open 

 spreading sore, with red, irregular edges, presenting a mouse- 

 eaten appearance, discharging a thin irritating pus, mixed 

 up with the debris of the tissues in which it is formed, 

 floating in serum and pus cells, it is said to be in a state of 

 Ulceration. 



Gangrene, or Mortification, that is, the entire death of the 

 whole or part of a tissue, — is apt to occur when the inflam-
