each person, forty with each instrument used. 
Twenty persons were tested. They were all students in the 
University of Kansas where the experiments were performed. 
Members of both sexes were included in the number. 
In Table I are given the number of correct estimates, over-esti- 
mates and under-estimates made at each point in the line where 
judgments were recorded. The sum of each column is also ex- 
pressed at the foot in terms of the percentage of all the readings 
taken in the position in which it stands.

The two parts of this table agree in their results. The distance 
was correctly judged the greatest number of times with the right 
side towards the sound, and under-estimated the oftenest with the 
left side in that position. The distance was over-estimated oftenest 
when the subject was sitting with his face towards the sound. 
The number of over-estimates exceeds that of both the correct
