exhibit of Unitarianism in this country presented at the seventy-fifth
anniversary of the formation of the American Unitarian Association. The
time required for a careful verification of facts made it impossible to
have the book ready at that date. The delay in its publication has not
freed the work from all errors and defects, but it has given the
opportunity for a more adequate treatment of many phases of the subject.
Much of the work required in its preparation does not show itself in the
following pages; but it has involved an extended examination of manuscript
journals and records, as well as printed reports of societies, newspapers,
magazines, pamphlets, and books. Many of the subjects dealt with, not
having been touched upon in any previous historical work, have demanded a
first-hand study of records, often difficult to find access to, and even
more difficult to summarize in an interesting and adequate manner.

I wish here to warmly thank all those persons, many in number and too
numerous to give all their names, who have generously aided me with their
letters and manuscripts, and by the loan of books, magazines, pamphlets,
and newspapers. Without their aid the book would have been much less
adequate in its treatment of many subjects than it is at present. Though I
am responsible for the book as it presents itself to the reader, much of
its value is due to those who have thus labored with me in its preparation.
In manuscript and in proof-sheet it has been read by several persons, who
have kindly aided in securing accuracy to names, dates, and historic facts.
