and concentric hypersemia) — the further will the lymph 

 exuded be removed in its primary character from that 

 transuded in the natural state of the part ; and the more 

 will its subsequent changes differ from those of normal nutri-

Degeneration may affect both the fibrinous and the cor- 

 puscular portion of inflammatory lymph. 

 The fibrinous part is subject to : 

 Drying into horny concretions. 

 Fatty softening, 

 Liquefactive degeneration. 

 Calcareous and" pigmental degeneration. 

 The corpuscular portion of lymph may also undergo : 

 Withering and drying. 



Conversion into granule cells by fatty degeneration. 

 Calcareous and pigmental degeneration. 

 Most commonly, however, into degeneration of the lymph 

 cells into blood cells, the whole of the lymph being trans- 

 formed into pus. Pus is a greenish-yellow creamy fluid, 

 consisting (under the miscroscope) of the liquor puris and 

 pus cells or corpuscles. Chemically, pus may be approxi- 

 matively tested by its solubility in liquor potass?e. 

 Suppuration is either: 

 Circumscribed, as in abscess. 

 Diffusive, as in erysipelas. 

 Superficial, as in some diseases. 

 The effects of inflammation upon the part or organ 

 involved are — 



Enlargement. Degeneration. 



Induration. Ulceration. 



Softening. Mortification. 



We thus see that very different, and even opposite, results 

 may follow from different degrees or kinds of inflammatory 

 action. 



Specific inflammations require merely to be mentioned 

 here. They occur in our domestic animals in the following 

 diseases : 



Farcy and glanders. 

 Rheumatism, melanosis. 

 Eruptive fevers of cattle. 

 Carbuncular erysipelas. 



The different exanthematous diseases of sheep. 

 These are distinguished from ordinary inflammation, and 

 from each other, in that —
