Stereo-

before a vowel properly stere-, combining form repr. Gr. στερεός solid, in various (chiefly recent) scientific and technical terms; for the more important of these see their alphabetical places. (In some instances referring to the use or principle of the stereoscope, and thus practically serving as combining form of stereoscope or stereoscopic: cf. STEREO¹.) Stereocentric a., Chem., applied to a formula indicating a hypothetical direction of the bonds of certain atoms in a molecule towards a common center (cf. stereo-isomer below, and STEREOCHEMISTRY). Stereo-comparator [COMPARATOR], (a) an instrument on the stereoscopic principle, used to superpose a pair of astronomical photographs taken at an interval of time, and detect any movement of a star or other object which has taken place in that interval; (b) a stereoscope having the object-glasses at a great distance apart, used in stereophotographic surveying to measure the distances of objects. † Stereo-electric a., applied to a (thermo-electric) current produced by contact of solids (opp. to HYDRO-ELECTRIC 1). Stereoglyph v. [Gr. γλύφ-ειν to engrave: cf. GLYPH] = STEREOMOULD v. Stereognostic a. [Gr. γνωστικός: see GNOSTIC], pertaining to the mental apprehension of the forms of solid objects by touch. Stereo-isomer Chem., one of two or more isomeric compounds which are held to differ by virtue of a difference in the spatial arrangement (not in the order of connection) of the atoms in the molecule; so Stereo-isomeric a., -isomeride (= -isomer), -isomerism. Stereomer, Stereometric a., Stereomerism Chem. [after ISOMER, etc.] = stereoisomer, -isomeric, -isomerism. Stereomonoscope [see MONO- and -SCOPE], an instrument invented by A. F. Claudet in 1858, with two lenses by which an image of an object is projected upon a screen of ground glass so as to appear solid, as in a stereoscope. Stereophantamascope, -phantascope [Gr. φάντασμα appearance, PHANTASM + -SCOPE], a form of kinetoscope giving a stereoscopic effect. Stereophotograph, a stereoscopic photograph; so Stereophotographic a. (abbrev. stereo-photo), pertaining to or involving the use of Stereophotography, the making of stereoscopic photographs. Stereophotomicrograph, a photomicrograph taken with a stereoscopic camera. Stereoplasm [Gr. πλάσμα: see PLASMA], (a) Biol. Nägeli’s term for the denser or more solid part of protoplasm (distinguished from HYGROPLASM); (b) Zool. an endothecal structure in corals, enveloping or connecting the septa, or forming a mass in the interior; hence Stereoplasmic a., consisting of or of the nature of stereoplasm (Cent. Dict., 1891). Stereospondylous a. Zool. [Gr. σπόνδυλος vertebra], characterized by completely ossified vertebræ, as the suborder Stereospondyli of amphibians. Stereostatic a., Mech. [see STATIC], applied to an arch constructed to sustain the pressure of a mass of solid matter, as a geostatic arch. Stereostatics, the statics of solid bodies. Stereotelemeter [TELEMETER], a stereotelescope with a scale or other contrivance for measuring the distance between objects viewed. Stereotelescope, a binocular telescope with the objectives a considerable distance apart (variable at pleasure), used in military operations, etc. Stereotrope, a form of thaumatrope or zoetrope fitted with a stereoscope, so that the figures appear solid and in motion. Stereotropism Biol. [see TROPISM], the growth or movement of an organism in a particular direction under the stimulus of contact with a solid body: so Stereotropic a., pertaining to stereotropism.
