Neurine :: Neurine (n.) A poisonous organic base (a ptomaine) formed in the decomposition of protagon with boiling baryta water, and in the putrefraction of proteid matter. It was for a long time considered identical with choline, a crystalline body originally obtained from bile. Chemically, however, choline is oxyethyl-trimethyl-ammonium hydroxide, while neurine is vinyl-trimethyl-ammonium hydroxide..

Breach :: Breach (n.) Specifically: A breaking or infraction of a law, or of any obligation or tie; violation; non-fulfillment; as, a breach of contract; a breach of promise..

Abbreviate :: Abbreviate (v. t.) To reduce to lower terms, as a fraction..

Decimal :: Decimal (n.) A number expressed in the scale of tens; specifically, and almost exclusively, used as synonymous with a decimal fraction..

Spectrum :: Spectrum (n.) The several colored and other rays of which light is composed, separated by the refraction of a prism or other means, and observed or studied either as spread out on a screen, by direct vision, by photography, or otherwise. See Illust. of Light, and Spectroscope..

Fractionate :: Fractionate (v. t.) To separate into different portions or fractions, as in the distillation of liquids..

Scrip :: Scrip (n.) Paper fractional currency.

Sexagesimal :: Sexagesimal (n.) A sexagesimal fraction.

Halo :: Halo (n.) A luminous circle, usually prismatically colored, round the sun or moon, and supposed to be caused by the refraction of light through crystals of ice in the atmosphere.

Stereoscopic :: Stereoscope (n.) An optical instrument for giving to pictures the appearance of solid forms, as seen in nature. It combines in one, through a bending of the rays of light, two pictures, taken for the purpose from points of view a little way apart. It is furnished with two eyeglasses, and by refraction or reflection the pictures are superimposed, so as to appear as one to the observer..

Iceland Spar :: Iceland spar () A transparent variety of calcite, the best of which is obtained in Iceland. It is used for the prisms of the polariscope, because of its strong double refraction. Cf. Calcite..
