86 NATURAL INHERITANCE. [chap. 



gave no evidence of discriminative selection in respect 

 to Temper. The good-tempered husbands were 46 per 

 cent, in number, and, between them, they married 22 

 good-tempered and 24 bad-tempered wives ; whereas 

 calculation, having regard to the relative proportions 

 of good and bad Temper in the two sexes, gave the 

 numbers as 25 and 21. Again, the bad-tempered hus- 

 bands, who were 54 per cent, in number, married 31 

 good-tempered and 23 bad-tempered wives, whereas 

 calculation gave the number as 30 and 24. This rough 

 summary is a just expression of the results arrived at 

 by a more minute analysis, which is described in the 

 Appendix, and need not be repeated here. 



Similarly as regards Eye- Colour. If we analyse the 

 marriages between the 78 couples whose eye-colours are 

 described in Chapter VIII. , and compare the observed 

 results with those calculated on the supposition that 

 Eye-Colour has no influence whatever in marriage 

 selection, the two lists will be found to be much alike. 

 Thus where both of the parents have eyes of the same 

 colour, whether they be light, or hazel, or dark, the 

 percentage results are almost identical, being 37, 3, and 

 8 as observed, against 37, 2, and 7 calculated. Where 

 one parent is hazel- eyed and the other dark- eyed, the 

 marriages are as 5 observed against 7 calculated. But 

 the results run much less well together in the other two 

 possible combinations, for where one parent is light and 

 the other hazel-eyed, they give 23 observed against 15 

 calculated ; and where one parent is light and the other 

 dark-eyed, they give 24 observed against 32 calculated.
