9 is another man, more like 7 than 5, also dark and dressed in 

 black clothes. He is fine looking and a professional man. 



To a class of twenty -nine students, of whom eight were young 

 women, the following questions were recently given : 



1. When you think of the numbers from 1 to 100, do you see them in any 

 particular form ? If so, will you write or draw it on paper? 



2. When you think of the alphabet from a to z, do you see the letters in any 

 particular form ? 



3. Have you any associations of color with the numbers or letters ? 



To these questions twenty-nine written answers were received, 

 disclosing four number forms and a few simple alphabet forms. 

 Immediately afterward, however, two others of the class told me 

 privately that they thought they did have forms, although they 

 had not reported them in writing. These were found, indeed, to 

 be perfectly well defined, and are shown in Figs. 6 and 7. The 

 other four are shown in Figs. 5, 8, 9, and 10 (a). One curious 

 alphabet form was found (Fig. 10, a), but no color associations. 

 This method of inquiry revealed in this case, at least, a much 

 larger percentage of number forms than that given by Galton. 

 These six forms present also some new types. Fig. 5 is from a 

 young man, who sees only the numbers 5, 6, 7, 8, and 9. Of these, 

 7 is by far the most conspicuous, and is described as a black fig- 

 ure, fine and perfectly formed, standing on a reddish background. 

 6 and 8 are less distinct ; 5 and 9 still less. Fig. 7 shows the num- 

 ber form of a young man, who sees the numbers from 1 to 9 in 

 Italics on a horizontal line. The others are straight and form a 

 right angle with the first. All the odd numbers appear to him as 

 weak, affording in counting unsatisfactory places to stop. The

even numbers are firm and strong, while 10 and its multiples are 

 much larger and more prominent. 



Fig. 8 is from a young woman who sees the numbers in a 

 straight line ; 1, 5, 10, 15, etc., appearing more distinct than the 

 others, with wider spaces after 5 and its multiples.
