cure of all wounds (except those healed by direct union or adhesion), for 

 the repair of fractures, and for the building- up of new material to supply 

 accidental loss of tissue. 



The process by which inflammation acts in these cases is as follows : 

 More blood is brought to the part, congestion ensues, and then exudation 

 takes place through the distended coats of the vessels. Lymph is formed 

 from the fibrinous material so exuded from the blood. Lymph, as pre- 

 viously stated, has a remarkable tendency to become organised. It 

 generally partakes, when organised, of the nature of the structure into 

 Avhich it is exuded. Thus if a cavity in the flesh has to be filled up, the 

 lymph when organised will fill it up with a new growth of similar struc- 

 ture, or if the broken ends of a bone have to be united the lymph will 

 knit them together and in due time become bone. 



Simple as this process may seem, there are many considerations con- 

 nected with it, which will be treated of in the next Chapter.

Inflammation, as previously stated, may be either a diseased or a 

 curative action (see para. 371, in previous Chapter). 



In the present Chapter we shall endeavour to explain the advantages 

 and means of inducing inflammation artificially in certain cases. 



1st. As supplemental to curative reparative action. 



2nd. As a stimulant to parts deficient in vital energ3^ 



3rd. As a means of producing what is usually termed counter-irrita- 

 tion, but which we think may more properly be regarded as stimulation.
