22 THE JUKES. 



girls who are legitimate, whose mothers (gen. 5) were sisters, chaste 

 and legitimate, whose father and mother (gen. 4) were legitimate 

 and chaste, whose mother (gen. 3, following the father's side) was 

 legitimate and chaste, whose mother was Ada, a harlot. Follow- 

 ing the mother's side (gen. 4), her mother was a legitimate child of 

 Delia, a harlot. Here the heredity seems not entailed. 



Now for the environment. The three sisters of generation 5 

 are industrious women, who work at tailoring, and are described by 

 their employer as always reliable, and doing their work by the time 

 promised. The oldest brother, who is a mason, has amassed some 

 $2,000 at his trade, which he has invested in a house and lot. He 

 is steady and industrious. Going back to generation 4, we find the 

 father a mason, tolerably industrious, who separated himself from 

 his brothers and sisters, the sum total of whose environment may 

 be thus expressed : Three sisters and one sister-in-law, prostitutes, 

 and the other sister-in-law a brothel keeper ; of the four men, one 

 brother kept a brothel, the other was a quarrelsome drunkard, one 

 brother-in-law was an habitual thief, who trained his sons to crime, 

 another served two years in State prison for forgery. This pair 

 thus measurably protected themselves and their progeny from the 

 environment of eight contaminating persons, all immediate relatives, 

 whose lives were, with few exceptions, quite profligate. Going 

 back to generation 3, we have no account of the environment, save 

 that there was no prostitution, while at the head of the line, we 

 find Ada on one branch and Bell on the other. 



In this case we again note that, in the fourth and fifth genera- 

 tions, while the heredity is mainly of the type of chasity, the en- 

 vironment has also been favorable to the same habits, but in gen- 

 eration 3 the characteristics of harlotry in Ada and Bell are not 

 reproduced as we might expect if heredity were the controlling 

 element in determining the career. If the history of the environ- 

 ment of that generation could only be obtained, it would, perhaps, 

 explain the interruption in the entailment. 



Case 4. Taking line 35, chart I., we have (gen. 7) an illegitimate 

 child, whose mother (gen. 6) was a prostitute, whose mother (gen. 

 5) was a bastard prostitute, whose mother (gen. 4) was a harlot, 

 whose father (gen. 3) was a bastard son of Ada, a harlot, while his
