These granulations are bright-red rounded elevations, about 

 the size of pins' heads, and consist of a group of cells round 

 a capillary loop. They have no lymphatics or nerves, are 

 not tender, and do not bleed readily. 



Hsemorrhagic Inflammation. — This form is characterized 

 by an exudation in which red blood-cells are in great 

 excess. The greater the vascularity of the tissue, and the 

 more severe the injury, the more likely is an exudation 

 to be hsemorrhagic. In acute pneumonia, the exudation 

 generally contains many red cells. This form of inflam- 

 mation too often terminates in gangrene. 



TERMINATION OF INFLAMMATION. 



Inflammation may terminate in resolution, in necrosis, 

 or in new growth. 



1. Resolution. — This is the commonest and most favour- 

 able termination of inflammation, It consists in the cessation 

 of the process, and the restoration of the parts to the normal 

 condition. 



The corpuscles of the stagnant blood gradually move 

 away until the current is re-established in the inflamed 

 area. Migration of cells and exudation of fluid ceases, and 

 the circulation becomes normal. The exuded fluid and cells 

 are removed firstly by the lymphatics, and afterwards by 

 the veins also. The remaining blood-cells or fibrin undergo 

 fatty degeneration and are removed. 



2. Necrosis. — Inflammation may terminate in death of 

 the implicated part. The more severe the injury, and the 

 feebler the resistance of the tissues, the more likely is 

 necrosis to occur. We apply the term 'necrosis' not to 

 the molecular disturbance occurring in suppuration and 

 ulceration, but to obvious death of tissue, and generally
