INDEX OF PERSONAL NAMES

**This Index is only intended to facilitate reference to the
authors quoted. The names of Darwin and Lamarck are omitted,
since to give all the references to them in a serviceable form would
involve a recapitulation of the Lectures. The Table of Contents at
the beginning sufficiently indicates the subject-matter.

Edited by Professor J. McKEEN CATTELL, Columbia University, with the coöperation of FRANK EVERS BEDDARD, F.R.S., in Great Britain.

Each volume of the series will treat some department of science with reference to the most recent advances, and will be contributed by an author of acknowledged authority. Every effort will be made to maintain the standard set by the first volumes, until the series shall represent the more important aspects of contemporary science. The advance of science has been so rapid, and its place in modern life has become so dominant, that it is needful to revise continually the statement of its results, and to put these in a form that is intelligible and attractive. The man of science can himself be a specialist in one department only, yet it is necessary for him to keep abreast of scientific progress in many directions. The results of modern science are of use in nearly every profession and calling, and are an essential part of modern education and culture. A series of scientific books, such as has been planned, should be assured of a wide circulation, and should contribute greatly to the advance and diffusion of scientific knowledge.

The volumes will be in octavo form, and will be fully illustrated in so far as the subject-matter calls for illustrations.
