The Causation of Sleep. By J. Cappie, M.D. Second Edition.
(James Thin.)—It would be manifestly impossible to do adequate justice to Dr. Cappie's argument in a brief notice. But we may commend his clearly written essay on the causation of sleep to those of our readers who are interested in this difficult but interesting subject. The essay before us was published in a different and less perfect form long ago, but the present book is almost a new work, so largely has it been augmented and altered. We do not venture to
pronounce in favour of Dr. Cappie's views as to the balance of the distribution of blood within the cranium (rather than an alteration in its amount) corresponding to the sleeping and waking states, but his statements are worthy of attentive study. An exquisite chrome- lithograph represents the circulation in the comatose and in the waking retina.
