a short time. Iodine was not in the solution, but iodine as ions was, 
probably as HI. For iodine as such could not be shaken out with 
the help of chloroform only, this however could be done when at 
the same time HNO, was added. 
Well then, this iodoform solution, exposed to the light, was not 
only unable to promote phagocytosis but greatly impeded it. 
This may appear from the table V. 
We see that in the NaCl-solution containing iodoform the phago- 
cytosis always remains below that in the pure NaCl-solution. We 
see for instance that after 10 minutes the phagocytosis in a pure 
NaCl solution amounts to 26.7 °/,, but in a NaCl-solution containing 
iodoform only to 15.4 °/,. 
After 1'/, hour the values are 56.9°/, and 39.8°/,. 
The following experiment for which, besides the (old) iodoform- 
solution which had been exposed to the light, also a fresh one had 
been taken, confirms the result.
