In the Preface to Vol. I., at p. x., I gave an account of the origination of some of the ideas embodied in the book. A few more such details may perhaps interest my Readers:——
I. p. 203. The very peculiar use, here made of a dead mouse, comes from real life. I once found two very small boys, in a garden, playing a microscopic game of 'Single-Wicket.'
