It will be seen from table G that the four salts, as already pointed 

 out in discussing the results of the individual tables, tend to fall 

 into two groups — ammonium and potassium with relatively short 

 reaction-times; sodium and lithium with relatively long ones. It 

 will also be seen that lithium is always less stimulating than 

 sodium, likewise that in the stronger concentration (3 m., 2 m.)
