condition, and may, I think, have been of the same character 

 as Doyne's " honey-comb " cases. 



(4) In 1872, Mr. Co well * published in much detail a 

 peculiar case of destructive irido-choroiditis in a father 

 and two of his children, and detachment of retina in a 

 third child, but as the author thought that the whole 

 affair was very probably syphilitic the case cannot be 

 quoted with confidence as an example of heredity. 



(5) I find notes of two sisters, set. 20 and 21 years, seen 

 at St. Thomas's Hospital in 1883, with identical extensive 

 superficial choroidal atrophy which appeared to have 

 come on at the age of 8 in one and 12 in the other, and 

 was apparently not progressing; there was no pig- 

 mentation of retina and no evidence of hereditary 

 syphilis. Both were myopic and had V. 1^7777 with 

 correction. The cases may have been of the same kind 

 as that of Miss A , referred to in the Section on Day- 

 blindness. 



(6) I am indebted to Mr. Fisher for the notes of a 

 case in which two sisters and a brother, aet. from 39 to 33 

 years in 1908, have changes similar to the last case (5) and 

 dating, as in that case, from late childhood ; the refrac- 

 tion hypermetropic. There was not the slightest facial or 

 dental evidence of syphilis. They were the third, fourth 

 and fifth born in a sibship of nine. The mother, who 

 died at 53, had had poor sight for many years but was 

 not blind. 



(7) Two cases of family choroiditis have also been 

 recorded by Hutchinson,t but in at least one of them there 

 was a strong suspicion of syphilis in the father
