Dear Sir
Though you are so considerate as to tell me not to write (& in truth my correspondence is very heavy) I must thank you for your very curious case of the peculiar form of quasi inheritance, where many descendants from the same parents are similarly affected.—2 This holds good in a remarkable manner with the deaf- & dumb; & is, I believe, quite inexplicable.—3
Dear Sir | Yours faithfully | Ch. Darwin
