ventional hand appears in both groups, — as does the backslanted hand, — 

 and the introverts exhibit the greatest variety of hands. 



In order to obtain material for an objective study thirty samples of 

 writing, namely those collected from the faculty group, were scored in 

 accordance with Freeman's instructions given in his book, "The Teaching of 

 Handwriting," for the five following characteristics: uniformity of slant, 

 uniformity of alignment, line-quality, spacing, and letter-formation. For 

 uniformity of slant the average was used of measurements by two individuals 

 with a protractor on fourteen two-space letters of the sample. The mean 

 angular slant of each sample was calculated and also the mean variation 

 from this average slant. For the study of line-quality the samples were 

 projected upon a screen by means of a Bausch-Lomb balopticon with a con-

sequent magnification. Again, two observers scored each specimen. The 

 three other graphic characteristics were measured according to Freeman's 

 instructions with the help of guide lines. Total scores on general quality of 

 writing were obtained by adding the partials, letter-formation being given 

 double weight in the final score. 



The scores on the contrasting samples may be compared (1) for general 

 quality and (2) for each graphic characteristic. 



The average total score for the fifteen extraverts was 20.23 with a mean 

 deviation of ±3.18; for the fifteen introverts 16.13 with a mean deviation 

 of ±4.1 1. The extraverts would seem to have a slight advantage in general 

 quality and to be slightly more coherent as a group. 



The range of total scores is from 13.5 to 25.5 for extraverts; from 6.5 to
