changed thereby, is called ROVIDAS'S hyaline substance, and the 

 property of the pus of being converted into a slime-like mass by a 

 solution of common salt depends on this substance. Besides this 

 substance we find in the pus-cells also an albuminous body which 

 coagulates at 48-49 C., as well as serum-globulin (?), serum- 

 albumin, a substance similar to coagulated albumin (MiESCHER), 

 and lastly peptone (HOFMEISTER). 



We also find in the protoplasm of the pus-cells, besides the 

 proteids, lecithin, cholesterin, xanthin bodies, fat, soaps, and 

 cerebrin (see Chapter X). HOPPE-SEYLER claims that glycogen 

 appears only in the living, contractile white blood-cells and not in 

 the dead pus-corpuscles. SALOMON has nevertheless found glycogeu 

 in pus. The cell-nucleus contains nuclein and some lecithin. 



The mineral constituents of the pus-corpuscles are potassium, 

 sodium, calcium, magnesium, and iron. A part of the alkalies is 

 found as chlorides, and the remainder, as well as the other bases, ex- 

 ists as phosphates. 



The quantitative composition of the pus-cells from the analyses 

 of HOPPE-SEYLER is as follows, in parts per 1000 of the dried 



substance :

MIESCHER has obtained other results for the alkali combinations, name-

 phosphate 4.2, sodium chloride 1.4, and phosphonc acid combined

In pus from congested abscesses which have stagnated for some 

 time we find peptone, leucin and tyrosin, free fatty acids and
