Dear Eyton

Will you forgive me troubling you once again?— I believe that you have attended much to Herefordshire cattle.² I have somewhere seen an account of two strains of this cattle differing slightly in colour,—I think in more white on face. Now what I want to know, is whether in these two strains there is any other difference whatever, so that you or a good judge, could generally distinguish these breeds by any slight character, independently of the one of colour.³ Will you be so very kind as to enlighten me, & not abuse me much as being abominably troublesome.

Your’s most truly | Ch. Darwin
