APPARENT ANTITOXIC ACTION OF SALTS 123 



eggs and larvae, in which the antagonism of ions has been made 

 apparent. It is not necessary to assume that there is any peculiar 

 power of mutual neutralization in lithium and magnesium. We 

 may reasonably suppose that the plain lithium-chloride bath is 

 not of the most favorable nature, because the metabolism of the 

 muscle immersed in it is not of the most economical character. 

 An admixture of magnesium chloride secures economy and a better 

 direction of the energy set free. But an excess of magnesium chlo- 

 ride is naturally unfavorable, because the same action carried farther 

 must result in depressed excitability. 



It seems to us a legitimate expectation that many other cases 

 in which mixtures of two salts have proved superior to either by 

 itself may be explained in equally simple ways.
