together with their progeny. 



A, 38.29 ± 0.43. 



S. D., 5.02 ± 0.30. 



In table 27, of 64 offspring the proportions are 6 S, 2S M. 55 I 

 11 VF. On the assumption of 6 zygotic factors, and that the matings 

 are of 5-factor and 2-factor parents, and that they wore equally of the 

 two types of matings of this class, then we should expect the follow- 

 ing proportions; 8 S, 42 M, 42 F, 8 VF. That this does not more 

 closely approximate the observed proportions is probably due to the 

 partial dominance of F over S. At any rate, it is a closer fit than 

 would be given on the 4-factor hypothesis. The details of each 

 family included in this mating are given below. 



Ale-2 Family. 



A family of English extraction; grandparents and parents living mostly 

 in Pennsylvania, Ohio, and West Virginia. Two of the children were born 

 in West Virginia, the other two in Ohio. The Father, a minister, ha 

 years the formula 135/70.8 inches; build 1.9 (27). His 3 brothers are tall. 

 Their father, who was a minister, always well, died at 81 year- 

 "diseases incident to old age," at 70 years having the formula M \ I 

 say, 2.3 (33). Their mother, who had 6 children, in youth was "delicat 

 She died at 85 years from old age, having the formula B T; build, say, 3 

 (28). Thus this side of the house is prevailingly of Blender build. 



The Mother, who had 4 children, suffered in middle age from erysipelas 

 and gallstones. She is living at 54 years, having at 50 years the formula 

 145/62 inches; build 2.7 (38). One of her brothers died at 18 year- from 

 tuberculosis, height 70 inches; another brother becanu feeble-minded alter 

 an attack of spinal meningitis, height 62.5 inches; one sister also die d from 



* M, medium weinl't; VT, very tall.
