Details of the Individual Members. 

 Pg Generation. 

 The mode of death of the four individuals repre- 

 sented is unknown. The existence of these four 

 members is postulated. The family tradition is 

 that the wife of Mr. A No. 1, and of Mr. B No. 3, were 

 normal, and that the suicidal mania came down 

 through the two husbands of this generation. 



P^ Generation. 

 In this generation Mr. A No. 1, and Mr. B No. 3, 

 are known to have been brothers-in-law. Since Mr. 

 B No. 3 was known to have married a woman No. 4, 

 unrelated to either family, it follows that Mr. A No. 1 

 could only be brother-in-law to Mr. B No. 3 by 

 marrying a sister of his. Accordingly, the woman 

 Miss B No. 2 is postulated, since nothing is certainly 

 known of her in the family or in the village. 



Mode of Death. 

 Mr. A No. 1 . . . . Died by drowning himself.* 



Mrs. A, nee Miss B No. 2 Death unknown. 

 Mr. B No. 3 .. .. Shot himself. 



Mrs. B, nee ? — No. 4 . . Died a normal death. 



Pi Generation. 

 In this generation Miss A No. 3 is known to be a 

 cousin of Mr. B No. 4, whom she married. He was 

 still living in 1907, and was then 80 years of age, and 

 had been sane all his hfe. This cousin marriage 

 confirms the conclusion derived from the known 



*ln all cases but this one, drowning was known to be by the 

 characteristic method already described.
