The formation of pus is termed suppuration, and it takes place 

 in three distinct vi^ays — (1.) circumscribed; (2.) diffused; and 

 (3.) superficial suppurations. 



As an example of the first or circumscribed form, I shall take 

 what is called an abscess or phlegmon, in which the suppura- 

 tion is enclosed in a cavity (as in the abscess of strangles) 

 whose walls are composed of areolar tissue. In the first stage, 

 the cells of the connective or areolar tissue are charged with 

 the material (lymph) formed by them during the first stage of 

 the inflammation ; there is an enlargement of the cells, their 

 nuclei divide, and for some time multiply excessively. This 

 is soon followed by division of the cells themselves, and round 

 about the irritated or inflamed parts, where single cells formerly 

 lay, pairs or groups of cells are subsequently found, out of 

 which a new formation (connective tissue) grows. In the in- 

 terior of this growth, where the cells were at an early period 

 abundantly filled with nuclei, numberless little cells soon ap- 

 pear, which at first still preserve the direction and forms of the 

 previous connective tissue corpuscles. 



These accumulations of little cells occur somewhat later, as 

 diffuse infiltrations of roundish masses encircled by the inter-
