My dear Sir
You will see in next Nor. of Cottage Gardener, or in one subsequent, a question about the running powers of Penguin Ducks.—1 Could you aid me in getting this Query answered by some private individual; or by its insertion in the Field, which I do not take in.—2
This morning I had letter from a great squire & breeder who tells me of a Hereford Heifer put several times to one of his Bulls (a sure calf-getter) & never produced, but now she has been put to another Bull has conceived.3
I shall beg him to save calf & put her to the 1st. Bull; & see if special sterility has descended. but with these big animals, years must elapse—
Yours very sincerely | C. Darwin
