SMITH UNIVERSITY OF PENNSYLVANIA PHILADELPHIA P. BLAKISTON'S SON & CO. 1012 WALNUT STREET COPYRIGHT, 1920, BY P. BLAKISTON'S SON & CO. THE MAPLE PRESS YORK PA PREFACE The writer, in studying the lives of early American chemists, encountered the name of _Joseph Priestley_ so frequently, that he concluded to institute a search with the view of learning as much as possible of the life and activities, during his exile in this country, of the man whom chemists everywhere deeply revere. Recourse, therefore, was had to contemporary newspapers, documents and books, and the resulting material woven into the sketch given in the appended pages. If nothing more, it may be, perhaps, a connecting chapter for any future history of chemistry in America. Its preparation has been a genuine pleasure, which, it is hoped by him whose hand guided the pen, will be shared by his fellow chemists, and all who are interested in the growth and development of science in this country. PRIESTLEY IN AMERICA There lies before the writer a tube of glass, eleven and one half inches in length and a quarter of an inch in diameter. Its walls are thin. At one end there is evidence that an effort was made to bend this tube in the flame. Ordinarily it would be tossed aside; but this particular tube was given the writer years ago by a great-grandson of Joseph Priestley. Attached to the tube is a bit of paper upon which appear the words "piece of tubing used by Priestley." That legend has made the tube precious in the heart and to the eye of the writer. Everything relating to this wonderful figure in science, history, religion, politics and philosophy is very dear to him. On all sides of him are relics and reminders of Priestley. Not all, but many of his publications are near at hand. After perusal of these at various times, and while reading the many life sketches of Priestley, there has come the desire to know more about his activities during the decade (1794-1804) he lived in America. Isn't it fair to declare that the great majority of chemical students think of Priestley as working only in England, his native land, and never give thought to his efforts during the last ten years of his life? It has been said that he probably inspired and incited the young chemists of this country to renewed endeavor in their science upon his advent here. There is no question that he influenced James Woodhouse and his particular confreres most profoundly, as he did a younger generation, represented by Robert Hare. Priestley again set in rapid motion chemical research in the young Republic.[1] He must therefore have done something himself. What was it? Is it worth while to learn the
