Hence we see that Alcohol in a dilntion of 1 to 100 has still a 

 pernicious effect on phaj^ocvtosis. Therefore it was advisable to expe- 

 riment also on weaker alcoholic solutions. 



The following table gives the result of this experiment.

Hence we see that alcohol in a dilution of 1 to 500 causes pha- 

 gocytosis to increase from 32.9 to 41.5, an increase of 277o- A 

 dilution of 1 to 20000 has still a favourable effect on phagocytosis, 

 but then it has already become slight. 



For shortness' sake we shall not give an account of other experiments; 

 we may state, however, that they gave the same results.
