Discusses crossed varieties of sheep and ducks.

My dear Darwin
I remember well what you mention about the slate coloured & White Muscovy Ducks. The Slate coloured, I imagine, were the produce of some cross raised at Birmingham. I have never seen them since nor do I think I ever reared any, as I lost the Drake.
The white always breed true to colour, as far as my experience goes, & I keep a large flock of them—(I have about 20 now)—
With however this exception that they have a great tendency to a Black Topper on head (exactly as represented in Bewicks plate).
Unless some considerable pains are taken in weeding out all these black topped Birds—the pure white would soon cease.
I never saw however a single black feather any where but on the top of Head.
The Black Lambs I also well remember. They were Southdown Ewes. The Ram I never saw— He was provided by Giblitt the Great Butcher—and I was told in answer to my enquiries that he was all but white, having a small patch only of Black—I think about the head. The flock was the queerest I ever saw, and every lamb being black in the lot, looks as if there was a positive law of some kind in the matter.
I will write to ask if M
The Ram appeared cross bred with a good deal of Southdown in him.
The only pure cross of Sheep I know (if one can use such a term)—are between pure Leicester & Southdown. I think it was the late Earl Morton who had a beautiful flock of these. They had no horns—& partook of each strain.
I have a small flock of the black & white sheep—which keep very true
to shape & colour. When crossed with Leicester they produce a race pretty nearly
balanced—except that there is a great tendency to Black lambs. The only
3 born this year are black. Having once got the black strain in this way from a
cross with the black & white & Leicester—it takes many
generations—at least 6 or 7—I am told by a friend of
mine—to get back the white colour—by continual crossing with a
Leicester. I can only speak to the 3
There seems little tendency in crosses of Sheep to return to primordial wildness—as the Irish have been almost renovated by the Leicester cross: and the Shropshire Down sheep are a greatly improved cross bred sheep.
I fear I have not added much to my former notes on these points.
What I wrote at time, may be strictly depended upon— In this letter you will see what are surmises only.
I should be very glad to hear of your getting to Malvern for 6 or
8 weeks. It is a glorious place for renovating the
health in. If my time & means would allow of it, I sh
I cannot tell you how glad I was to see you so well in London. It was a great pleasure to see so many old & valued faces—& all looking so well. I very much want to see Susan and Caroline again.
If you go to Malvern I shall try to come over & get a weeks bathing while you are there. I have some curious enquiries about you & your Book sometime. You ought to occupy a cage by the side of the Gorilla in the British Museum sometimes to let the Public see you.—
Kindest regards to M
