New Fourth Edition Revised and Enlarged Suplee's Mechanical Engineer's Reference Book A Hand-book of Tables, Formulas, and Methods for Engineers, Students and Draftsmen By Henry Harrison Suplee, B.Sc., M.E. Member American Society of Mechanical Engineers; Membre de la Société Des Ingénieurs Civila de France; Mitglied des Vereines Deutscher Ingenieure; Member of The Franklin Institute. Illustrated. 964 pages. 16mo. Full limp leather, round corners, gilt edges, thumb index. $5.00 net T1 HIS book is intended to form a standard hand-book for the mechanical engineer and the designer of machinery, supplying in convenient form the general information which is constantly required. In the new fourth edition the few errors in the previous edition have been corrected and an Appendix of forty pages added, containing a variety of useful information. Several features make this the one up-to-date complete accurate work for mechanical engineers,-more space has been devoted to Mathematics than in any other similar reference book in English,-the subject of machine design is very amply treated,—the arrangement of the matter is unexcelled, and fully illustrated, which together with the complete thumb index, makes it just the book for quick reference.
