A Handbook of Sewage Utilization. By Ulick Ralph Burke. (E.
and F. N. Spon.)—This is a compact and handy little book, showing what are the chief evils of our present state of anarchy as regards sanitary questions, and what steps have been taken to bring about a remedy. Mr. Burke has made use of official publications, such as the reports of the Sewage and the Rivers' Pollution Commissions, and he states concisely and impartially the principles upon which the main schemes for utilising the sewage of our towns are based. The grow- ing importance of this question, which appears from Mr. Disraeli's prominent allusion to it in his speech at Manchester, and from the different bills which have been either introduced or promised this session, makes the book singularly appropriate at the present time, and will add to its usefulness.
