The Water - Supply of Towns and the Construction of Waterworks. By
W. K. Burton. (Crosby Lockwood and Co.)—Mr. Burton describes himself as "Professor of Sanitary Engineering in the University of Tokyo," and "Consulting Engineer to the Tokyo Waterworks." This is itself an interesting illustration of Japanese progress. The material of his book is partly derived from experiences in Japan, though such great English works as the Liverpool reservoir at Lake Vyrnwy are also brought into use So technical a subject cannot be dealt with in these columns, but we may briefly say that this volume will be found interesting, at least in parts, by non-technical readers. We may instance the remarkable and, we may add, satisfactory facts relating to the purification of contaminated water by natural processes. It seems that this is effected by the much-abused microbe, which consumes the contaminating matter as its natural food.
