both of whom there was a latent neuropathic taint. The family consisted 

 of three individuals, two sisters, A. and B., and an elder brother who was 

 married but had no family. 



_JL_ married a^first cousin, and although neither of them was insane 

 nor epileptic, yet they had two children epileptic and one a congenital 

 imbecile /> this terminated the stock on that side. That there was latent 

 insanity was shown by the result of the marriage and the fact that a sister 

 became insane. A., however, married into a healthy, virile stock; she 

 became insane at 38, although living many years after she never recovered, 

 the exciting cause was the death of a son by suicide (S.) at 18. There were 

 two daughters who became mothers of families, the eldest son of one 

 suffered with a marked epilepsy, but no other evidence of neuropathy was 

 shown in this generation. The taint seems to have disappeared, inasmuch 

 as there are healthy, grown-up members of the fourth generation. 



Fig. 6. A pedigree illustrating marriage of first cousins. A genius 

 was the product who married a healthy woman, and the family consisted of 

 an eldest son, committed suicide (S) ; a second son, epileptic (E) ; a daughter, 

 healthy, unmarried; and a fourth son a genius. This man was a genius,

but had an extremely well-balanced mind ; all his five children are healthy 

 in spite of collateral insanity. 



Fig- 7- A family of drunken and insane people. The figures with 

 half black circles are insane; the same with the cross indicates drink and 

 insanity; the circles with only a cross indicate excessive drinking. The 

 two stocks show a marked difference; one side the maternal is practically 

 free from any taint ; almost every member of the paternal stock is unsound.
