blood-vessels and nerves, as the cartilage and 

 cornea, where, at least, no question of a direct 

 or reflex paralysis of the blood-vessels can arise. 



In the non-vascular textures, the increased 

 action is limited to increased heat and nutrition. 

 These two forces are directly related, so that a 

 certain quantity of heat can produce a certain 

 quantity of nutrition, and vice versa; but 

 neither can arise from nothing. Either requires 

 some other mechanical, chemical, electrical, or 

 thermal motion to be given to the matter in 

 the inflamed part, to increase the healthy 

 motions which are always there. 



This increased motion may come from with- 

 out by injuries and accidents, or from within 

 by diffusion of active substances into the cornea 

 and cartilage. According to the amount of 

 increase of motion, will be the amount of 

 inflammation. In the vascular textures, the 

 increased motions of oxidation and nutrition 

 outside the vessels act directly on the contents 

 of the nearest vessels, and, from the increased 

 action between the vessels and textures, the 

 dilatation of the vessels, the disappearance of 

 the serous layer, and the heaping up of the red 

 and white corpuscles arise.
