THE HEALEY PICTURE PUZZLE 
This ingenious device has proved to be a great aid in measuring the mentality of the feeble- 
minded. The person examined must put in the board squares which will make the people 
pictured do suitable things, and this gives the examiner a chance to see whether he is 
able to observe and reason intelligently. Two boys in the middle of the picture, for 
instance, are evidently kicking a football, and the square bearing the picture of a football 
should be put in the opening. If the person tested puts in a picture of a cart wheel, or a 
pair of shears, it shows a lack of sense. Of course, the interpretation of the evidence 
furnished by such tests as this depends on the previous experience of the examiner, and 
upon a large body of normal and abnormal persons having been tested, so that the examiner 
knows about what a person of a certain grade of mentality should do. 
taken on the previous day, who are 
accused of serious offenses or who have a 
previous police record, are interviewed 
in the big gymnasium. 
Judging by their appearance or their 
conversation, their records, or the 
circumstances connected with their mis- 
deeds, Dr. Bisch selects the prisoners 
who he thinks are likely to be mentally 
(iio 2.) 
deficient. They are then taken to his 
laboratory for examination. If they 
are found to be normal, they are 
turned back to the police officers with a 
statement to that effect, and prosecution 
follows. If they are found to be 
abnormal, a detailed report and diag- 
nosis are submitted. On the basis of 
this, recommendations are made for
