specimens from similar surroundings have confirmed, namely, 
the unmistakable predominance of positive reactions to the shadow 
test. Tables IV and V show the same thing, and also show the 
rather remarkable variation of recovery time at different tests by 
the same, and different individuals. For example, in Table IV 
the recovery time of F and G at the very first test is in extreme 
contrast, and at the ninth test almost the same contrast, but in

reversed order. The record of the same specimens at 2 p.m. 
shows much less contrast in these points, though they are not lack- 
ing. In some cases the contrast between certain individuals 
was much greater than these. In one case a specimen after a given 
test retracting and remaining in its tube for nearly half an hour, 
in exact time twenty-six minutes. It does not seem possible to 
explain these as in any wise due to anything in the nature of the 
stimulus.
