A Treatise on the Sanitary Management and Utilization of Sewage.
By W. Menzies, Deputy Surveyor of Windsor Forest and Parks. (Long- man and Co.)—Mr. Menzies has given his subject that systematic con- sideration which it requires. If the sewage of our towns is to be applied to some useful purpose instead of poisoning our rivers and polluting our shores, the general principles of the subject must be ascertained and embodied in a public Act of Parliament. He thinks that the solid matter of sewage may be separated by filtration and conveyed to the place where it is wanted, and that the liquid which remains should be applied to pasturage near the towns, which the corporations should be authorized to acquire. •
