Entered according to Act of Congress, in the year 1863, by WALKER, WISE & Co., in the Clerk's Office of the District Court of Massachusetts. CAMBRIDGE: Allen & Farnham, Printers. BV 4585 W3 1864 ADVERTISEMENT TO THE THIRD EDITION. Ir would be difficult to give any account of a book compiled as this has been. Of the original English work, scarcely more than the title and the introductory essay have been retained, while the changes from the first American edition are most radical. It is sent out again simply because our sick rooms need some such visitor. It does not pretend to supply the want, only to stand in the gap until something better shall offer. J. F. W. W.
