The Memoir here given to the public is based on a biographical sketch
prepared by the writer at the request of the Massachusetts Historical
Society for its Proceedings. The questions involving controversies into
which the Society could not feel called to enter are treated at
considerable length in the following pages. Many details are also given
which would have carried the paper written for the Society beyond the
customary limits of such tributes to the memory of its deceased members.
It is still but an outline which may serve a present need and perhaps be
of some assistance to a future biographer.
