Description:

‘Dear Professor Pearson,

The case of the offspring of 2H276 becomes much more remarkable in view of the fact, mentioned in your letter of 3^rd inst., that the hybrids which produced the aberrant albinos were the offspring of a waltzer and extracted albinos.

I should think it is quite likely that this is the only mating of extracted albinos together, with such ancestry and the experiment must certainly be repeated. I think it is quite likely that we shall get this result again in view of the fact that hybrids from extracted albinos & waltzers produce far less than ¼ albinos.

I think I could probably find out about the crossbreeding from Steer’s as I have his letters. But tho I have had definite assurances as to the purity of the albinos from some of the other people, I have had reason to doubt their statements in one or two cases. For example the albino parent of [illeg.] 12 was, I believe, stated to be pure but produced 3 yellow (with black eyes) x 2 greys; a result which I have never got from albinos which I know to be pure by breeding them myself.

But I will look thro’ Steer’s letters when I get back to to Oxford, in about 5 days time. I am yours faithfully,

A.D. Darbishire’
