[ Their last organic act was to meet the dark wave of this tide of sectionalism on the strand, breast high, and roll it back upon its depths. R. Choate , Addre es, p. 427. IMG:content-0488.png:[blocks in formation] section-beam (sek's hon-bēm), n. In warping, a roller which receives the yarn from the spools, either for the dre ing-machine or for the loom. In the latter case, also called yarn - beam. Е. Н. Knight. section-cutter (sek's hon-kut"ėr), n. An instrument used for making sections for microscopic work. Some forms have two parallel blades; others work mechanically, and consequently with more precision. The specimen from which the section is to be taken is often frozen by means of ether-spray or otherwise. Also called microtome. sectionize (sek's hon-iz), v. t.; pret. and pp. sec tionized, ppr. sectionizing. [ The sectionized parts became perfect individuals on the day of their division. T.

A cut surface; a plane exposed by section. The section - plane , as made by the saw, pa ed just sinistrad of the meson. Buck's Handbook of Med. Sciences, VIII. 109. sectioplanography (sek"shi-o-plā-nog'ra-fi), n. [ sectio (n-), a cutting off, + plan us , plane, + Gr. -γραφία , γράφειν , write.] A method of laying down the sections of engineering work, as railways, in which the line of direction is made a datum-line, the cuttings being plotted on the upper part and the embankments on the lower part of the line.
