3. Pale orange on back and backles, with a few black specks ; 



legs pink. 



4. Pale pile ; legs yellow. 



5. Pale pile ; legs pink. 



6 and 7. Yery pale pile ; both with legs pink. 



6 Hens. Two of these were coloured all over ; three had the

 the breast and abdomen uniform pale brown ; one was white, with

6. White with trace of reddish lacing on neck ; legs pink. 



B. Offspring of cock with slightly yellow back, and hens white 

 with black specks. 



8 Cocks. One of these was a moderately coloured pile ; six were 

 pale or very pale piles; and one was not a proper pile, but had 

 spots of orange and black on wings, hackles, and tail. Four of 

 them had yellow legs and four had pink legs. 



9 Hens. Two of these were typical piles, with pale back laced 

 with fawn colour and brown breast, one rather more deeply 

 coloured thaiT the other. One was reddish brown all over with 

 black specks. The rest, six in number, were white with scattered 

 specks of colour, and two of them had a yellowish tinge on head 

 and neck-hackles. I give below the notes for each of these 

 individually : — 



4. White with minute specks of black. 



5. Yellow on head and hackle ; back and tail with many black 



spots. 



6. Yellow on head and hackle ; black specks on back. 



7. White with a few grey marks on feathers. 



8. Yery slight specks of black here and there ; othei wise 



white. 



9. Y^hite with few black spots. 



Five of these hens had pink legs and four had yellow legs.

 the leg colours noted in the F„ generation. Yellow leg means 

 yellow skin, and what I have called pink leg means white skin. 

 The yellow skin was a character of the White Leghorn hens of 

 the parents in the cross, the white skin a character of the Black-
