Tr•amtcays. By D. Kinniard Clark, C.E. (Crosby Lockwood and Co.)—An

exhaustive treatise by an experienced engineer on this modern and yet undeveloped mode of locomotion. In it will be found full information respecting the construction, cost, and working of the tram- ways in the principal towns of Great Britain, with an account of various initial experiments. Furthermore, as a competent committee have decided on the superiority of steam over horse-power, Mr. Clark devotes Part V. to the description and construction of tram locomotives. The volume is abundantly illustrated with some first-class engravings of sections, plans, ste. With this we may notice The Application of Electricity to Railway Marking, by Willian Edward Langdon (Macmillan and Co.), a useful and unpretending little volume on block systems, and other electrical contrivances for the prevention of accidents. It is so simply written, that any railway telegraphman may easily make himself master of its contents.
