The above 10 pedigrees contain 34 cases of this day-blindness with 

 colour-blindness : 18 males, 15 females, and 1 sex not recorded. The 

 same childships contain at least 45 (probably more) normals : 17 male, 

 22 female, and 6 or more sex unrecorded, total about 80 to 85. 



The total of 84 cases mentioned at p. cxxix of the lecture is made up of 

 my own and Grunert's series, including some single cases of mine not 

 given above, but useful in relation to sex prevalence, and three others 

 published since the appearance of Grunert's paper by Wehrli, 1903 

 (Abstract in NageFs Jahresbericht, xxxiv, p. 92) ; Bjerrum, 1904 (Ab- 

 stracted, ibid., xxxv, p. 105, and again p. 205) ; Konne, 1906 (abstracted- 

 ibid., xxxvii, p. 78, and original reproduced in full in K.M.f.A. (Beilage, 

 heft), xliv, p. 193. In Bjerrum's case, two brothers of the (male) 

 patient were also affected.
