likewise much too low a figure. A mistake in counting is therefore 
not to be thought of. 
We now revert to the question, to what extent the leucocytes 
which have been placed during a night in a solution of NaCl 0.9 °/, 
and which consequently have lost partly or entirely their phagocy- 
tarian capacity can be revived again by an addition of chloroform. 
To this series of experiments has been added one with Todoform 
and one with CaCl’, as we wished to investigate to what extent the 
stimulating effect of these substances corresponded with that of 
chloroform. 
The table shows that if phagocytes which have been left exposed 
during one night to a low room-temperature, are acted upon for 
I'/, hour by Chloroform in a concentration 1 : 500.000, whilst the 
suspension is afterwards brought into contact for 15 minutes with 
carbon at 37°, the Phagocytosis will be raised from 8,7 to 11.1°/,. 
If we give more time to the suspension to take up carbon viz. 30 
minutes, then the favourable effect of chloroform makes itself more 
plainly felt, the phagocytosis rising from 20 to 34.2" 4. Injurious, 
however, the effect of chloroform proves to be at a contact of the 
phagocytes with carbon during 45 minutes; perhaps the cells, which
