Handbook of Rural Sanitary Science. By C. F. Gardner, W.

Berry, C. N. Cresswell, and Thomas Bennett. Edited by Lay •Marsh, M.D. (Smith and Elder.)—Dr. Marsh two years ago offered a prize for the best essay on "Rural Sanitary Science." • In this volume we have at full length the successful essay, and representative extracts from three others, which were honourably mentioned by the judges (Mr. Bailey Denton, and James Howard, of Bedford), together with a chapter reviewing the subject, by the editor himself. With this may be men- tioned Purification of Water-Carried Sewage, by Henry Robinson and J. C. Melillo (Smith and Elder), a very valuable summary of results obtained up to this time by the various sewage operations carried on by sundry great towns.— Safi t a s Sanitatum et Omnia Sanitas, by Richard Metcalfe, Vol. I. (Co-operative Printing Company), is the work of en enthusiast for the bath, in which he finds an effective remedy for many disorders, and a substitute for vaccination, which he opposes with the usual want of reason which gentlemen of his way of thinking display.
