ANILINE.--A term strictly applicable to coal-tar colours, but commonly used for brilliant tones very soluble in water. BÂTONNÉ.--_See_ PAPER. BISECT.--A term applied to a moiety of a stamp, used as of half the value of the entire label. BLEUTÉ.--This word implies that the blueness of the paper has been acquired since the stamp was printed, as the result of chemical action. BLOCK.--An unsevered group of stamps, consisting of at least two horizontal rows of two each. BOGUS.--An expression applied to any stamp not designed for use. BURELÉ.--A fine network forming part of design of stamp, or covering the front or back of entire sheet. CANCELLED TO ORDER.--Stamps which, though postmarked or otherwise obliterated, have not done postal or fiscal duty. CENTIMETRE (CM.).--The one-hundredth part of a metre = .3937 inch. CHALKY, OR CHALK-SURFACED.--Before being used for printing, paper sometimes has its surface coated with a preparation largely composed of chalk or similar substance: this renders the print liable to rub off if wetted; and, in combination with a doubly-fugitive ink, renders fraudulent cleaning practically impossible. CLICHÉ.--The ultimate production from the DIE, and of a number of which the printing PLATE is composed. COLOUR TRIALS.--Impressions taken in various colours from a plate, so that a selection may be made. COMB MACHINE.--A variety of perforating machine, which produces, at each descent of the needles, a line of holes along a horizontal (or vertical) row of stamps, and a short line of holes down the two sides (or top and bottom) of each stamp in that horizontal (or vertical) row. And _see_ PERFORATION. COMMEMORATIVES.--A term applied to labels issued chiefly for sale to collectors, and commemorating the contemporaneous happening, or the anniversary, centenary, &c, of some often unimportant or almost forgotten event. COMPOUND.--_See_ PERFORATION. CONTROL.--An arbitrary letter or number, or both, printed on the margin of a sheet of stamps, for facilitating a check on the supply. Also used to denote a design overprinted on a stamp (_e.g._ Persia, 1899) as a protection against forgery. [Illustration: EXAMPLES OF SOME PHILATELIC TERMS.
