From tlio above table it is shown: 1. That in 1 — 2 " '„ solutions 

 of citras natricus in 0.9% "1 Sod. Chi. the phagocytarian power 

 is nil. ; 



2. that the phagocytarian capacity again partially reappears, when 

 the cells are transferred into 0.9 % solutions of Sod. ('hi. The per- 

 manent decline of the phagocytarian power still amounts to 28%- 



5. Effect of Fluornatrium. 



Fluornatrium being also much used for preventing the coagulation 

 of the blood, it seemed important to us also to study the effect of 

 this medium on the phagocytosis. 



TABLE XI. 

 Effect of Fluornatrium. 



Here we see that when the leucocytes have been exposed to 

 a solution of Fluornatrium of 2 %> 1 % or 0.65 % (isot. with 

 0.9% NaCl) the phagocytarian power is entirely paralysed, yea, 

 that even after transferring of the phagocytes in a solution of 0.9% 

 Sod. Chi. it shows to have been entirely destroyed for ever. Han-, wt 

 may conclude that NaFl is a powerful poison for the protoplasma 

 of tin- phagocytes. 



V. Effect of acid and alkali. 

 1. Effect of acid. 



The important part which the alkaline reaction of the blood- 

 plasma seems to play, not only in connexion with the degree of
