experiments, and found that in a mixture of 100 c.c. ^ Ca 

 (NO 3 ) 2 +20 c.c. 2| ra KC1 a still larger number of eggs 

 formed embryos than in the preceding experiments. On the 

 other hand, it could be shown that the addition of small 

 amounts of KC1 was without effect. 



TABLE XIV 



The size of the antitoxic dose of KC1 in Ca(NO 3 ) 2 poi- 

 soning is, in fact, extraordinarily larger than the antitoxic 

 dose of Ca(NO 3 ) 2 in the case of KC1 poisoning. Similar 

 relations exist for the antitoxic effect of NH 4 C1 upon CaCl 2 

 poisoning. 



TABLE XV 



The antitoxic effects of NH 4 C1 are not as great as those 

 of KC1. Similar experiments with NaCl and LiCl as anti- 

 toxic substances were without positive result. 



Similar experiments were then performed with MgCl 2 .
