chloroform to 5.000.000 NaCl-solution this favourable effeet is still 
visible, it is true, but it is very slight. 
The following experiment, made only with solutions of chloroform 
of 1 to 500.000, but this time with different periods of contact 
between carbon and leucocyte-suspensions confirms what has been 
said above. 
We see from this table that already after 30 minutes the accele- 
ration of phagocytosis, effected by chloroform, has manifested itself 
at its maximum value. After an hour it still exists, but in a slight 
degree. The figure 27.5, with the note of interrogation, must be owing to 
a mistake in the concentration of the solution. Indeed other prepa- 
rations of the same suspension gave after an action of 45 minutes
