Blanching.--The word to blanch not infrequently occurs in the sense of to put a fair appearance on a thing, to slur over, deceive. See Iliad, Bk. XII. 223. Florio, in his "Worlde of Wordes," 1598, says, under the word "Biancheggiare," "metaphorically it is taken to raile at one secretly." The sense is obvious here.
