[Asterism] Thirty copies are printed on Large Paper, 1 vol. 4to. with INDIA PROOFS before the Letters of the Portraits, price £3. 3_s_. "A monument raised late, it is true, but not too late, to a great and modest genius. A national biography which illustrates and elevates our ideas of the past, and a contribution which the world will recognize to the European history of Science." _Dublin University Magazine_, September, 1865. "A work which displays a high order of literary ability, careful antiquarian research, much ingenuity, and withal thorough honesty of purpose. "[Lord Worcester], his life, told as Mr. Dircks has told it, is one of much interest. "Here we have an elaborate--although of course not a completely exhaustive--account of his life; at any rate the most complete account of him ever likely to be written--a work filled with abundant evidence of the most painstaking research, a work written in a generous and sympathising spirit, and with every attribute of conscientiousness." _Engineering_, 5th January, 1866. "The production of this volume is no common achievement; Mr. Dircks has undertaken to write the life of a man about whom the public know very little. "He has, we think, collected some curious information, and established the claim of the Marquis to be the first constructor of a steam-engine. The reprint of the celebrated _Century of Inventions_ adds greatly to the interest of the volume."--_The Spectator_, 14th September, 1867. * * * * * One Volume, 8vo., price 21_s_, only 100 copies printed, WORCESTERIANA; A COLLECTION OF
