PETERSFIELD.—Two lectures were delivered on Tuesday and Wednesday evenings, in the Petersfield British Schoolroom, by Mr. Sheldon Chadwick, the subject being, ‟Science of the Soul, with wonderful and amusing experiments on sleep, trance of mesmerism, and biology.” The subject was treated with an unusual degree of talent by the lecturer, his force of language being powerful, and the experimental part set the whole audience in rapturous fits of laughter.
