Series 4. Crosses between various Breeds ivhich lay different 

 coloured Eggs. 



This series of experiments was undertaken with the intention of 

 observing the influence of egg-characteristics belonging to the breed 

 u.'sed as male parents towards the characteristics of i^, eggs. 



(1) Reciprocal matings between Chinese whites from the Joken 

 and Kainei districts and Japanese univoltine breeds, "Aojiku" and 

 " Chusii." 



Egg-colour of the Chinese breeds: dark-slate, more or less shaded 

 with green in various degrees, sometimes without any green shade. 

 We call this colour Chinese normal colour. 



Egg-colour of the Japanese breeds (Figs. 1, 3, and 11): brownish 

 slate, more or less shaded with pink or purple. This is the ordinary 

 egg-colour of Japanese breeds.
