Although the title of this work is sufficient to declare its contents, a few prefatory remarks may not be superfluous as to its design and the manner in which that design has been carried out It has ever been to the writer a matter of surprise and regret, that although the art of turning has been so long and so successfully pursued in this country, both by artisans and amatours, no work has appeared in the English language treating upon the subject, except one or two sketches and imperfect treatises.<br><br>Some years since Mr. Holtzapffel advertised a forthcoming series of seven volumes, intended to supply this manifest deficiency in our scientific and mechanical literature, and the subject would have been haudled by him in a thoroughly exhaustive and masterly manner.<br><br>The untimely death of that gentleman occurred after the publication of the first three volumes, which are indeed complete in themselves, and of immeasurable value to the mechanic and amateur; but which are unfortunately only introductory, "simple turning by hand-tools" being the special subject of the proposed fourth volume. Tho present proprietors of the firm of Holtzapffel & Co. having, in their catalogue even up to the time of the most recent edition, continued to advertise the seven volumes, amateurs especially have anxiously hoped for the publication of some part at least of the remainder of the series.
