volume of air. For example, on a load of 6000 ft.-lhs., though the 
heavier man, his lung-ventilation was less than half that of the sedentary 
subject of fig. 1. 
A good deal of trouble was taken with the degenerate subject of 
fig. 8. He did not know how to pedal, and even after practice could 
not be induced to pedal in time with a pendulum. The record shows him 
to be useless in the ranks and not worth training ; his stamina was far 
too low. His response to any form of mental stimulus was unusually 
tardy. An order, such as “ Stop pedalling,” would only be obeyed after 
the lapse of several seconds. Curiously enough, his respiratory centre 
appeared to operate after a similar lag, with the result that the volume 
of breathing did not increase at the normal rate upon starting a spell 
of work ; anoxaemia supervened and made him stop the exertion at a load 
which to a normal healthy man would be easy. 
Very few malingerers were met with. They were easily detected, 
as they would allege a load was more than they could support before the 
curve had reached its crest.
