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.

_The Oceanic Hydrozoa_; a description of the Calycophoridae and
Physophoridae observed during the Voyage of H.M.S. _Rattlesnake_ in the
years 1846-50, with a general introduction. Ray Society. London, 1859.

_Evidence as to Man's Place in Nature_. Williams & Norgate. London,
1863.

_On our Knowledge of the Causes of Or
