70 HEREDITY AND SOCIAL FITNESS 



multiplication tables up to 40, but was defective in the application 

 of his knowledge; writing was always very illegible. Since he appeared 

 to be at a mental standstill for nearly the whole of the last year, was 

 taken out of school 1910. Could be relied upon to polish floors and 

 mow the lawn. In spite of his superior attainments and his slightly 

 larger fund of general information, is rather more timid and retiring 

 than his brother, who looks to him for counsel in whatever emergency 

 may present itself. 



Summary of Line E. 



Line E may be summarized as one which, by reason of the matings 

 of its defective members with individuals carrying similar defects, has 

 never gained traits necessary for social efficiency. It we except IV-128, 

 who is thought to be illegitimate though of unknown paternity, no 

 member of this line has been able to maintain existence without much 

 charitable aid. WTiereas sUght perseverance and aggressiveness have 

 in some instances been brought in, calculating abiUty and other mental 

 traits have been too uniformly lacking to make the former of avail. 

 With the single exception of the illegitimate IV-128, who has married 

 into a fair strain, all later representatives of this line are without issue, 

 since they are in the custodial care of the State. The defects of this 

 line accordingly bid fair to terminate with the present generation.
