page no 166 note † “Practice multiplying simple numbers; ask nobody to help you, and you will rapidly get familiar with and fond of the slide rule … . Instructions are of no use. Find all this out for yourself.”—Perry, Practical Mathematics, 1907, p. 11. “Much the best way of beginning to use the sliding rule is not by working given questions, but by setting the slide at hazard, and learning to read the questions which are thus fortuitously worked.”—De Morgan, Slide, or Sliding Rule, P.C. xxii. (1842).

The appeal to hazard is not new. Recorde took the random replies of “suche children and ydeotes as happened to be in the place,” and astounded his friends by getting right answers.—De Morgan, Recorde, P.C. xix. p. 331.
