Darwin was not in perfect health, and his wife and daughters took care that he should retire early. My opportunity for conversing with him came next day. In the soft spring morning before sunrise I looked out of my bedroom window and saw Darwin in his garden, inspecting his flowers. His grey head was bent to each bush as if bidding it good-morning. And what a head! All that the phrenologists had written was feeble compared with a look at that big head with its wonderful dome, and the lobes above each luminous eye. All the forms of organic nature had contributed something to represent them visibly in the constitution of the head able to interpret them.
