Knowledge is Power. By Charles Knight. (Bell and Daldy.) Bohn's

Scientific Library.—This volume comprises two of Mr. Knight's early publications, one on the "Results of Machinery" and the other on "Capital and Labour." The result is a mixture of political economy, industrial history, and description of manufactures and machinery, which conveys much useful information, and at the same time will enable the average reader to understand the principles that govern the relations of capital and labour. Mr. Knight traces •mart in his progressive eourse from the savage to the social state, and lands him at last amongst modern appliances and modern ideas, and he takes the opportunity of describing en passant the successive inventions that have led to the grand result. His style and mode of treatment are well known, as also his taste for those subjects, and the facility he acquired by constant practice.
