of inflammation, in connection with fibrous tissues and in 

 strong vigorous subjects. 



4th. Blood Exudations. As already stated, blood-globules 

 escape through the walls of the vessels in all inflammations, 

 though seldom in such quantity as even to stain the tissues. 

 Minute ruptures of the capillary vessels are not uncommon 

 with punctiform clots in the tissues, but extensive escapes of 

 blood are usually indicative of a specially unhealthy type of 

 inflammation, usually associated with a specific and deadly 

 poison, as in anthrax, rinderpest, swine-plague, purpura 

 hsemorrhagica. They are further most common from newly 

 formed vessels, which are yet soft and possessed of little 

 power of resistance. 



5th. Croupous Exudations. These are deposited on dis- 

 eased surfaces in the form of false membranes, composed 

 mainly of cell-elements, epithelium, and pus-corpuscles in a 

 thin network of fibrine, mucin, or both. To these belong 

 the membranous products of croup and diphtheria, aiid the 

 false membranes that appear independently of these poisons 

 on violently inflamed mucous membranes (croupous enter- 

 itis, etc.) 



RESULTS OF INFLAMMATION. 



Resolution. This is the condition in which a slight in- 

 flammation, which has not advanced beyond the stage of 

 liquid effusion, has the exudate reabsorbed, and tlie blood- 

 vessels and tissues restored to their healthy condition. If 

 this occurs with extraordinary rapidity the term delitescence 

 is applied to it, and there is danger of its reappearance else- 

 where by reason of clots from the capillaries being suddenly 

 loosened and washed onward to block other capillaries in the 

 lungs or other distant organs. This occurrence of a sec- 

 ondary disease at a distance, when a first has suddenly sub- 

 sided, has been named metastasis, and is usually due to the 

 blocking of the capillaries by blood-clots.
