These papers consist of Wead correspondence concerning personal matters and Philosophical Society of Washington affairs, particularly the memorial meeting for Simon
Newcomb in 1909. Also included are two letters from Simon Newcomb to John A. Kasson, one concerning a committee of Congress to investigate the possibility of establishing
the metric system in the United States.

and filled the unexpired term of Simon Newcomb as President of that organization in 1909, after Newcomb's death.
