244 CONSTITUENTS OF PUS CELLS. [BOOK I 



Presence of It has been shewn by Salomon 1 that pus generally 



Glycogen in contains very appreciable quantities of glycogen, and 

 P US - this fact agrees with certain histological observations of 



Kanvier 2 . Thus a distinction which Hoppe-Seyler 3 sought to esta- 

 blish between the colourless cells of the blood and their descendants, 

 the pus corpuscles, can no longer be maintained. 



The Extractive Matters of Pus Cells soluble in alcohol and ether. 



The chief of these are cholesterin, fats and derivatives of glycerin- 

 phosphoric acid ; free fatty acids may be likewise present in old pus 

 and form crystalline deposits. 



The Mineral Matters of Pus Cells. 



These consist of a small quantity of sodium chloride and of earthy 

 phosphates. Their amounts, as found by Hoppe-Seyler, will be 

 learned in the next paragraph.

 lysis of PUS sodium sulphate.
