E. /V. Scripture, 
tinue the experiments till a mistake is made in feeling two points as one. 
Now apply the æsthesiometer to the scale and record the distance be¬ 
tween the points. Repeat the measurement ten times. Find the average 
and average variation. 
B. Repeat the experiments of A on the back of the neck in a vertical 
direction. 
C. Adjust one æsthesiometer to 30""" as a standard. Apply it for a 
moment to the cheek of the subject. Adjust the other æsthesiometer to 
an arbitrary distance. Apply it likewise to the cheek. The subject is 
to say whether the second distance was greater or less than double the 
first. According to the answer adjust the second æsthesiometer differ¬ 
ently and repeat the experiment. Proceed as in A, the first æsthesiom¬ 
eter being kept at the constant distance of ßo1"“ and the second being 
gradually changed till a judgment of “ equal to double the first” is ob¬ 
tained. Take ten records.

Points 
to he 
noted. 
i. Note that the results depend somewhat on the skillfulness of the ex¬ 
perimenter. 2. Note that psychologically double does not necessarily 
correspond to absolutely double. 
Questions. 
I. What improvements would you suggest in the apparatus and the 
method of experimenting? 2. How would you express the relation be¬ 
tween space on the cheek and space on the neck in your experiments ?
