PHILADELPHIA: COLLINS, PRINTER, 705 JAYNE STREET. 64-17.34 (/EW Exchange Univ. of Western Ontario APR 1 3 '34 PREFACE. THE publication of this treatise having been long delayed, and having at the same time been much inquired after, a few words of explanation seem necessary. The esteemed friend of the publisher, the talented and industrious author, died on Sunday, June 20, 1869, at New Lebanon, N. Y., where he had for years had charge of the extensive laboratory of Messrs. Tilden & Co., manufacturing chemists; leaving the book in an incomplete and imperfect state. This caused a postponement of all preparations for its being sent to the printer, and it was some time before the services of a competent editor were obtained who would finally prepare it for, and supervise its passage through, the press. The undersigned is happy to be able to state that for this important work he obtained the assistance of one of the very ablest chemists in this country, who has expended upon it much conscientious care and time. He believes that in its present form it will be found to be one of the most valuable as well as useful technical treatises which he has yet offered to the American and British public.
