no. 3.] PSYCHOLOGICAL EXAMINING IN THE UNITED STATES AEMY. 761 



Medical Department make better records on the intelligence examinations than does the 

 Medical Corps. (See Part II, chapter 14.) The contrast with the Quartermaster Corps, which 

 makes a very similar intelligence record but is much less schooled, is especially interesting in 

 considering to what extent examination alpha is dependent on schooling. The Dental and 

 Veterinary Corps also stand high relative to other officers as to schooling, and low as to 

 intelligence rating. That the most frequent schooling among dentists, and especially among 

 veterinarians, is three years college is doubtless explained by the fact that many dental colleges 

 and most veterinary colleges normally offer a three-year course. (See also table 303.)

Fiq. 26. Distribution of schooling. Engineers stand second only to medical officers in length of schooling reported. The officers of the Quarter- 

 master Corps, though they are the least schooled of the groups here compared, make as high an intelligence rating on examination alpha as do 

 the officers of the Medical Corps. (See tables 302 and 303.)
