LIST OF HUXLEY’S WRITINGS

This list is offered, not as a bibliography in the technical sense, but as an indication of the sources in which the vast majority of Huxley’s scientific and general work may be consulted most conveniently.

The Scientific Memoirs of Thomas Henry Huxley.  Edited by Professor Sir Michael Foster and Professor E. Ray Lankester; in four volumes.  London, Macmillan & Co.; New York, D. Appleton.

This magnificent collection is intended to contain all Huxley’s original scientific papers, brought together from the multitude of scientific periodicals in which they appeared, with reproductions of the original illustrations.  The only exception is the monograph on Oceanic Hydrozoa.  The first volume appeared in 1898; the second in 1899, and the others are to follow quickly.

Collected Essays by T.H.  Huxley; nine volumes of the Eversley Series.  Macmillan & Co.  London, 1893-95.

This set, edited by Huxley himself, contains the more important of his more general contributions to science and his literary, philosophical, and political and critical essays.  Each volume has a preface specially written, and the first volume contains his autobiography.
