Darwin Correspondence Project

From Francis Galton   22 March 1870

42 Rutland Gate. S.W.

March 22. 1870

My dear Darwin

Another litter;— this time of 4,— and all of them are true silver greys.— Also, one of the does (mentioned in my last letter as transfused from a black & white) is dead.1

My stud now stands as overleaf. I call each silver grey by the name of the colour of the rabbit from which it has been infused. I also give the particulars of my first batch. You will see that there was much less variety in my pairs then, than there is now.

I hope to try a new mode of transfusion upon a wholly new stock, taking younger rabbits and putting much more alien blood into them.

Ever very sincerely ys. | F. Galton
