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.
