the horse suffering from inflammation the normal buffy coat 

 is increased. Tlie blood of inflammation also coagulates 

 more firmly and contracting most toward the centre assumes 

 a cupped appearance on the surface. 



These changes in the blood and nervous system are asso- 

 ciated with an increase of body temperature and other mani- 

 festations of fever proportionate to the extent and violence of 

 the inflammation. Again, in both inflammation and fever, 

 the disease process may be of a strong type (sthenic), or of 

 a low type (asthenic, adynamic). 



mFLAMMATION IN NON-VASCULAR TISSUES. 



Inflammation in tissues unprovided with blood-vessels 

 may be observed in the irritated transparent cornea of the 

 eye, or the cartilage covering the ends of bones in joints. 

 Each when inflamed has its nutritive function impaired and 

 loses its clear, translucent aspect, so much so that in the case 

 of the eye one can no longer see into its interior. There 

 may be as yet no real thickening, and no film of exudation 

 formed on its surface. It is the pre-existing structures that 

 have become opaque by change in the process of their nutri- 

 tion. If a thin slice of this inflamed cartilage is treated 

 with picric acid and placed under the microscope it is found 

 that the nuclei within the cartilage-cells have become indi- 

 vidually larger, that the cells embedded in the cartilaginous 

 matrix are more numerous than is normal, and that, when 

 the inflammation is most active, even cell- walls are no longer 

 formed, but that a mass of rapidly multiplying nuclei is 

 taking the place of the solid transparent matrix. As in the 

 vascular tissue, so in the non-vascular, the power to build up 

 the sound tissue (cartilage, corneal tissue) has been tem- 

 porarily lost, while there is a mere growth of a cellular or 

 embryonic tissue at the expense of the pre-existing struct- 

 ure. It remains to be added that in the inflamed cartilage 

 or cornea there is an abundant infiltration of wandering
