Note 2 — PART I.

There is one other bird, not given in the above list, that is pure Sebright except that his legs are yellow. Until I find out by further breeding of the Sebright stock whether yellow legs are present in it, this case must remain doubtful. On the basis of a two factor color-difference one Sebright (as to color) is expected in 16 birds, and one in 64 on a three factor basis. Some Sebrights had been raised along with the back cross, hence the possibility of contamination.
