National Academy of Sciences.

NOTICE.

Members of the Academy who have memoirs for publication should send them to the President, O. C. MARSH, Yale College, New Haven, Connecticut, before December 1st, 1884.

In order to avoid delays in printing, the manuscript should be complete, and if illustrations are necessary the drawings should be carefully made and given on separate sheets.

The printing of the second volume of the memoirs of the Academy is now nearly finished, and it is expected that this volume will be ready for distribution within a few weeks. There are still remaining some copies of the first volume of the memoirs, published in 1867. I hope that members who have not received this volume will inform me.

A. HALL,
Home Secretary.

WASHINGTON,
October 22, 1884.
