" Miss Hassiebrock strode through a pair of chromatic portières, with them swinging after her, and into an unlit kitchen, gray with dusk.

I do not see why, since America and her autumn woods have been discovered, our leaves should not compete with the precious stones in giving names to colors; and, indeed, I believe that in course of time the names of some of our trees and shrubs, as well as flowers, will get into our popular chromatic nomenclature.

Our language has not terms enough to signify the different delicate shades; our factories have not the stuff whose hues might make a chromatic scale for them.

An autumn wind was blowing, and long plumes of dust whisked up out of the curving street and swept over the ill-kept yards, past the cabins, and toward the sere fields and chromatic woods.

I now completed the theory of this construction by correcting the aberrations, spherical as well as chromatic.

The aberrations, both spherical and chromatic, are here worked out very well.

In mathematics I find Chances, Figure of the Earth with variable density, Differential Equations, Partial Differentials, sketch for an instrument for shewing refraction, and Optical instruments with effects of chromatic aberration.

Then, too, there are the birds down among the watercress and the brooklime in the clear pool below the spring, moorhens occasionally awakening the echoes by running down a weird chromatic scale or calling with their loud and mellow note to their friends and relations over at the brook; here, too, the softer croak of the mallard and the wild duck is also heard.

The lecturer then, by means of diagrams which he placed upon the blackboard, showed the forms of various makes of photographic lenses, and explained the influence of particular constructions in producing certain results; positive and negative spherical aberration, and the manner in which they are made to balance each other, was also described by the aid of diagrams, as was also chromatic aberration.

The remainder of the lecture was devoted to an explanation of the determination of the chromatic relations of the colors of the spectrum.

I inquired cheerfully, and he, staying his claw-like hand in mid-air, made reply "A chromatic in tones of sad colour, with golden accidentalsKashmir night-lights.

I mean that in music, for instance, the writers of the stricter ancient music might have seen that the art was likely to develop a greater intricacy of form, an increased richness of harmony, a larger use of discords, suspensions, and chromatic intervals, a tendency to conceal superficial form rather than to emphasise it, and so forth.

They are formed by the sound a. In violent pain arising from a physical cause, the cries assume three different tones: one grave, another acute, the last being the lowest, and we pass from one to the other in a chromatic order.

Absolute trueness is that adopted by theorists, who divide the gamut into five notes and two semi-notes; the note into nine commas, or shades of tone; the chromatic semi-tone into five, and the diatonic semi-tone into four.

Mr. H.T. Cresson, of the Academy of Natural Sciences, Philadelphia, has critically examined the various Aztec clay flutes, whistles, etc., which are there preserved, and has reached the following conclusions: "I. That upon the four-holed clay flageolets the chromatic and diatonic scales can be produced with a full octave.

" It should commence brilliantly, then intermediate variations, in which sharps and flats would play a considerable part, and, finally, after a chromatic scale, down not up, of accidentals, it should finish in the minor rallentando diminuendo, and end like the comic overture (whose we forgetHAYDN'S?), where all the performers sneak off, and the conductor is left alone in his glory.
