 cannot attribute the rapid decrease in time taken in (b) to 

 the tuition until we know the time-curve for the same 

 process without tuition. 



The systematic experiments designed to detect the pres-

 cally unanimous against it. So, too, was the general behavior 

 of the monkeys, though I do not consider the failure of the
