SPECIFIC FERMENTS OF THE CANCER CELL 421 



seven hours later showed an increase in polymorphonuclear 

 cells from 21 to 37 per cent., and a corresponding decrease 

 in small mononuclear leukocytes. The third count made, 

 twenty-five hours after the first, showed the characteristic 

 increase of large mononuclear cells w r hich were here regis-

 and L large mononuclears. 



tered at 27 per cent., with a normal at the first injection of 

 10 per cent. Two and one-half hours later the percentage 

 of this form of cell had returned to normal, which was 

 again followed by a slight increase. It is probable that the 

 highest registration of large mononuclear cells occurred 

 between the second and third counts.
