The theme of this little volume is the potential expansion of the powers of sensory perception. The three main senses described are indicated by the three part titles: The Commonly Unseen; The Commonly Unheard; The Commonly Unfelt. The treatment is anecdotal and colloquial. The ""wonders of the commonplace"" supply the main substance and a wide variety of incidents furnish illustration. The author's interest in oriental mysticism is reflected indirectly at some points. For those who need this sort of stimulation to quicken their sensory apprehensions.
