I sometimes, in my sprightly moments, consider myself, in my great chair at school, as some dictator at the head of a commonwealth. In this little state I can discover all the great geniuses, all the surprising actions and revolutions of the great world in miniature. I have several renowned generals but three feet high, and several deep-projecting politicians in petticoats. I have others catching and dissecting flies, accumulating remarkable pebbles, cockleshells, etc., with as ardent curiosity as any virtuoso in the Royal Society.
