Description of work
'Using soot from a candle because, while '. . . in every sound man's head, there is a regular succession of ideas of one sort or another, which follow each other in train. . . just like the images in the inside of a lanthorn turned round by the heat of a candle.' (Vol III Ch. 18), a black page might better suggest ' . . . ideas whirling round and round about . . . all obfuscated and darkened over with fuliginous matter.' (Vol III Ch. 19)
