of it appear to have shown themselves in either of her 

 parents, Nos. 3 and 4, A. 



Generation C. 



Nos. 1 to 14, 20, and 24 were almost certainly 

 normal. I was able to examine Nos. 16, 17, 22, 23, 

 and 26. The}' were quite normal. 



No. 15. Affected daughter of affected parents 

 Nos. 14 and 21, B. She died of pneumonia at the age of 

 50. Had double cataract as a child. One eye had been 

 operated on successfully^ when she was twenty-four 

 years of age. The other e3^e was operated on twentj^- 

 one years afterwards, with the result that sepsis 

 set in, and enucleation became necessary. At the 

 age of fortj^-eight she suffered from mammary carcinoma, 

 which was extirpated a year later. It was probably 

 recurrent in the dorsal vertebrae before death. There 

 was no post-mortem examination. 



No. 18. Sister of No. 15, C. Cataract in both 

 eyes since childhood. Operated upon at the age of 

 forty years. 



No. 19. Brother of Nos. 15 and 18. Father of No. 

 15, D. Had double cataract since a child at school. 

 Operated on at thirty-five j^ears of age. 



No. 21. The seventh child. He lives abroad and is 

 inaccessible. Had double cataract since childhood. Was 

 operated upon when twenty-four years of age, at about 

 the same time as most of the other affected members 

 of the family. 



No. 25. The twelfth child had double cataract. 

 The condition does not seem to have appeared till 

 she was eighteen years old. After the cataract 

 had been present for five years the right eye was operated 

 on. In the spring of 1909 she died, at the age of twenty- 

 eight years, of Addison's disease. 



Note. — In the family Nos. 15 to 26, C, there was a 

 child who died in infancy, and he is not included in the 

 Chart, as no information is available concerning him. 



Generation D, 



All the members of this generation are yet quite 

 young. The defect may appear in them at a later age.
