NEW MECHANICAL WORK.

D. APPLETON & CO. are preparing for publication a Dictionary of Machines, Mechanics, Engine Work and Engineering, designed for Practical Workingmen and those intended for the Engineering Profession. Edited by Oliver Byrne, formerly Professor of Mathematics, College of Civil Engineers, London, author of "The Calculus of Form," &c. Comprising nearly 1500 engravings and 2000 pages of letter-press. To be completed in about 30 Numbers-price 25 cents each.

This work will contain, in a condensed form, all that is truly valuable for reference and for study, and embody works which, from their high price, remain almost sealed books to the working engineer and apprentice.

Every useful and new improvement will be amply treated of, and placed before the workingman in a practical and hence in a useful form. The style in which this work will be written and illustrated, may be considered eminently calculated to mature the abilities of that numerous and ingenious class pointed out by the phrase, 'Workingmen.'

It is confidently hoped that the working Engineers of the United States of America will avail themselves of the opportunity, and assist the publishers in producing this work, by which they are assured that the advancement of Mechanical Engineering will be promoted in a manner creditable to the land of Washington, Fulton and West. Practical men are invited to forward suggestions and contributions that may enhance the character of the work, or develop the art of the American Engineer or Machinist. All communications or contributions to be forwarded to the publishers.

D. APPLETON & CO., 200 Broadway.
