sodium hydrate was added; Na,f>0 C, that the base 

 added was ] / 80 n in respect to sodium hydrate, but 

 besides was 0,5 n in respect to NaCl. 10, C and 2, C 

 indicate 0,1 and 0,2 normal chlorid. 50, S and 10, S 

 0,5 and 0,1 normal Na 2 So 4 . 



In the following tables the headings have the same 

 signification; and for reasons easily understood, to each 

 base only salts of the corresponding metal were added. 



The three bases, potassium, sodium and lithium 

 may, when equivalent amounts are taken, be considered 

 quite similar as regards action, allowing for errors ol 

 experiment; and likewise all the salts used in the ex- 

 periments have the same power in lessening the ha?mo- 

 lysis when added in equivalent amounts. This depends 

 most probably on the fact that these bases on the 

 one hand and their salts with the same acids on the 

 other, are dissociated to very nearly the same extent. 

 The action of the salts is still perceptible, although 

 rather slight in such small doses as 0,02 n which when 

 diluted by 50 times as much blood mixture, corresponds 

 to a 0,0004 normal salt solution - - when most diluted. 

 In all cases, even in the most diluted salt solutions,
