The experiments can nearly all he carried out by children, are fully described, do not involve the purchase of expensive material, and are in all cases made subservien to the author's purpose, hich is to enable her youthful papils to obtain sound knowledge by appealing to nature herself in as pleasant and as thorough a way as possible.
