A large folio volume has just been published, by John

Weale, contain- ing coloured views and architectural drawings of the Tubular Bridges, the Conway and Britannia, with some remarkable girder bridges ; in all forty-five plates. The coloured lithographs are from drawings by George Hawkins they give a vivid idea of the works as they appeared both in progress and in completion. The technical drawings by Mr. Edwin Clark, the editor, explain every part and stage of each work. The book thus conveys a forcible insight into the nature of those vast mechanical tri- umphs : it may serve as a guide to the imitators of the great engineers, and will be of much value as an historical record.
