have been weakened already, are further impaired by the longer 
exposure to 37°, in the presence of chloroform. For this supposition 
there is a good deal of reason, seeing that longer heating at 37° 
begins to have an injurious effect even in a pure NaCl solution. 
As we see from the table the stimulating effect of lodoform is about 
equal to that of Chloroform. 
To a much more considerable extent than these two, however, 
Calcium stimulates the phagocytes in these experiments. 
3. EFFECT OF BENZENE ON PHAGOCYTOSIS. 
Of Benzene (C,H,) the following concentrations in a NaCl-solution 
of 0,9 °/, were made: 
1 Vol. to 5000, 1 to 10,000, 1 to 500,000 and 1 to 5,000,000. 
The fluid acted upon the suspensions during an hour; then they were 
brought into contact with carbon for 30 minutes at 37°.
