afford the clearest and truest mode of displaying at a glance the modi- 
fication of color due to the varying proportion of the three primary 
neutra grey. 
_ Hence it will appear, that any hue not purposely diluted with black 
or white, is composed of a compound of a binary color with neutral 
gray. Hence a convenient nomenclature suggests itself as follows: 
the first column containing the binary colors.

These colors are supposed to be of the standard or maximum attain- 
able intensity. 
They may be diluted with white on the one hand, forming tints; or 
with black, forming shades. : 
Mayer’s triangle may be repeated with these modifications; but as 
the color tends to extinction, either in the direction of perfect blackness 
Or perfect whiteness, the number of compartments in the triangles may 
be diminished as the dilution of the colors increases. Thus, the whole 
may be formed into a double pyramid of color, converging to white 
above and to black below. ‘ 
The author has been much indebted to Mr. D. R. Hay, the ingenious 
author of the ** Nomenclature of Colors,” and other works, not only 
for specimens of colored papers formed by the actual mixture of the 
three primary colors, but also for many valuable suggestions, of which, 
in the course of this paper, he has freely availed himself.
