Table 335. — Percentage distributions of mental ages of whites and negroes examined individually at Camp Sheridan. 



Tables 336 and 337, giving the mental age according to recommendation, show the rigid 

 way in which mental age was used as a dividing line for the five types of recommendation. 



A study of the disease conditions of these men brings out striking differences, not only 

 between the whites and the negroes, but between the total draft and this group. Separate 

 figures for the whites and negroes in the entire draft are not available. The figures for venereal 

 diseases for the first million men are not valid, because in the early operation of the draft men 

 with these diseases were in many instances rejected by the draft boards. Among the second 

 milli on men 5.4 per cent were reported by the camp examiner after their first examination at 

 camp as having a venereal disease. This per cent would doubtless come up to 7 after more 

 careful examinations were held. 



In the Sheridan group of men examined individually the total number of men with venereal 

 diseases is 70.5 per cent among the negroes, 18.5 per cent among the whites. Of the negroes 

 33 per cent had both syphilis and gonorrhea, while of the whites only 9.4 per cent had both. 

 Thus the percentage of venereal disease in the negro is about four times as great as in the 

 whites for men of this class. On the other hand, the percentage of chronic diseases is for the 

 negro half what it is for the whites — 17.8 per cent for negroes and 34.1 per cent for the whites. 

 Infectious diseases were reported for 4.8 per cent of negroes and 14.4 per cent of whites. It is 

 easily seen from these percentages that the number of men free from disease was small. The 

 whites stand ahead with 33 per cent clear, while only 17.3 per cent of the negroes were clear.
