A new color guide.—A new color guide by Dr. Ropert RmwGway,' the 
well known ornithologist, is practically an entirely revised and much enlarged 
edition of his earlier nomenclature of colors (1886) with 17 plates and 186 
colors as against 53 plates and 1115 colors in the present work. The color 
work was done by A. Hoen & Co., Baltimore, and is much more uniform in 
different copies than in the earlier edition, which was hand-stenciled from 
several mixings of the same color; while in the present work each color for 
the whole edition of 5000 copies was prepared from one lot of color and uni- 
formly coated at one time. 
The work is designed to be equally useful to botanists, florists, artists, 
dyers, merchants, and chemists who require a standard color scheme. The 
colors have evidently been standardized to a degree of accuracy not hitherto 
attained in any color chart. The colors are one-half by one inch, arranged on 
a heavy gray paper in three vertical columns of 7 colors each. All the colors 
are named as well as symbolized, but if a given color comes between “hermosa 
pink” (xf) and “‘eosine pink” (1d), it could be designated 1e. In this 
manner about 2385 additional colors or a total of 3500 can be designated. 
Undoubtedly exception will be taken to some of the names, but in this the 
personal equation plays such a large part that decisions must be rather arbi- 
trarily rendered. The primary colors have been standardized by Dr. P. G. 
Nurtinc of the U.S. Bureau of Standards. 
A table of percentages of color, together with an explanation of the amount 
of white, black, or neutral gray used as above, will give an approximately ready 
clue to the reproduction of any color in the guide, the only epee factor 
being the possible lack of standardized primary colors to begin wi Defini- 
tions of the principal color terms, such as color, shade, tint, Pg ‘ise, ete., 
which are used almost interchangeably by aoa people, will repay c 
study by those not familiar with their exact u 
A slight error on p. 12, due to a Siena should be corrected. 
Mr. F. A. WALPOLE had no connection with the color project of the American 
gg eager Society, the preparation of which was delegated to the late Dr. 
L. M. Unb oop, Dr. W. A. Murritt, and the writer. Mr. WALPOLE 
died before "the committee was appointed, and the project was abandoned 
after two years’ work by the committee in favor of Dr. Ripcway’s work 
which had not previously come to their notice.—P. L. RICKER.
