The mind of Mr. Bagges was decidedly affected—beneficially—by the lecture on the Chemistry of a Candle, which, as set forth in a previous number of this journal, had been delivered to him by his youthful nephew. That learned discourse inspired him with a new feeling; an interest in matters of science. He began to frequent the Polytechnic Institution, nearly as much as his club. He also took to lounging at the British Museum; where he was often to be seen, with his left arm under his coat-tails, examining the wonderful works of nature and antiquity, through his eye-glass. Moreover, he procured himself to be elected a member of the Royal Institution, which became a regular house of call to him, so that in a short time he grew to be one of the ordinary phenomena of the place. Mr. Bagges likewise adopted a custom of giving _conversaziones,_ which, however, were always very private and select—generally confined to his sister’s family. Three courses were first discussed; then dessert; after which, surrounded by an apparatus of glasses and decanters, Master Harry Wilkinson was called upon, as a sort of juvenile Davy, to amuse his uncle by the elucidation of some chemical or other physical mystery. Master Wilkinson had now attained to the ability of making experiments; most of which, involving combustion, were strongly deprecated by the young gentleman’s mamma; but her opposition was overruled by Mr. Bagges, who argued that it was much better that a young dog should burn phosphorus before your face than let off gunpowder behind your back, to say nothing of occasionally pinning a cracker to your skirts. He maintained that playing with fire and water, throwing stones, and such like boys’ tricks, as they are commonly called, are the first expressions of a scientific tendency—endeavors and efforts of the infant mind to acquaint itself with the powers of Nature. His own favorite toys, he remembered, were squibs, suckers, squirts, and slings; and he was persuaded that, by his having been denied them at school, a natural philosopher had been nipped in the bud. Blowing bubbles was an example—by-the-by, a rather notable one—by which Mr. Bagges, on one of his scientific evenings, was instancing the affinity of child’s play to philosophical experiments, when he bethought him Harry had said on a former occasion that the human breath consists chiefly of carbonic acid, which is heavier than common air. How then, it occurred to his inquiring, though elderly mind, was it that soap-bladders, blown from a tobacco-pipe, rose instead of sinking? He asked his nephew this.
