Hence roe may conclude, that there is no difference between the 

 action of chloride of potassium and chloride of sodium. 



3. Effect of chloride of calcium. 



The great importance which, according to the most recent in- 

 vestigations must be ascribed to the ions of calcium, l ) in the con- 

 stitution of the fluid-matter of the tissues, induced us to test also 

 the effect of this medium on phagocytes. 



With this object in view, we dissolved various quantities of chloride 

 of calcium in the serum of the blood of a horse and mixed the 

 suspension of leucocytes thus obtained with carbon.

Effect of calcium chloride. 



An addition of 0.0J % of Ca Cl t 6 aq. to the serum already 

 produces an increase of the phagocytarian capacity of 22.6 °/ ; 

 by the addition of 0.1 % Ca Cl 2 6 aq., the effect is somewhat
