Chromatism.—This term is here intended to apply specially to those cases in which any organ of a plant assumes a colour approximating to that of the petals, or in which the normal green is replaced by tints of some other colour.

Scientific Chromatism constitutes an ensemble of propositions, of which art will be able to make use, though indirectly, as information useful for a better understanding of the laws of light in presence of nature.

Associated words: chromatics, colorific, colorist, chromatism, chromatology, lake, decolorant, mordant, intinctivity, iridescent, iridescence, prismatic, pigmentation, fugacious, fugitive, fugacity, monochromatic, monochrome, polychromy, polychromatic, suffuse, suffusion, imbuement, chromatic, achromatic. color, n. ruddiness, redness, flush, blush, rosiness; semblance, pretext; variety, shade, kind, species; pl. flag.

I am at present engaged on the theory of the achromatic object-glass, with regard to spherical chromatism—a subject upon which, I believe, nearly all our text-books are silent, but one nevertheless of vital importance to the optician.
