The values of n’ for w< 3-00, were also rejected in the calcu- 
lation of the constants, as with such light weights the work 
varies greatly with a slight variation of strength. [This will 
be fully dlabinsed hereafter.] Taking the constant c as the 
eats of the strength, and assuming that the work done with 
(hich we at different times is proportional to the strength, 
= Sig show to be true for the weights not rejected), 
om n'= observed number of lifts before exhaustion 
and n=the same, reduced to the basis the mean strength 35°79

* This 8 point is important. Try to lift 20 kgrs. in a second through 0°70 meters. 
Rows Will fail to aa once, pi Ao yet not be exhausted, The question of maximum 
attainable with different weights is wholly different from the one under 
ses mn. I think Mr. Haughton has pas Aer} this influence on his own
