The total number of cases of idiocy of all grades reported is 134, 

 which amounts to 1.07 per 1,000 population. Among the whites in 

 the United States the proportion was, in 1890 (Eleventh Census), 1.55 

 per 1,000 population. 



Of the 134 cases, 84, or more than three-fifths, were males ; 50, or less 

 than two-fifths, females, giving the proportion of 168 to 100. Among 

 the whites enumerated by the Eleventh Census the proportion of 

 male to female idiots was 118 to 100. Sixty per cent (51 individuals) 

 of the male and 74 per cent (37 individuals) of the female idiots were 

 cliildren and adolescents. Many of the cases of idiocy under con- 

 sideration are in all probability due to diseases and neglect in early 

 childhood.
