AMUSEMENTS IN
MATHEMATICS

BY

HENRY ERNEST DUDENEY



AUTHOR OF "the CANTERBURY PUZZLES: AND
OTHER CURIOUS PROBLEMS," ETC.

In Mathematicks he was greater
Than Tycho Brahe or Erra Pater:
For he, by geometrick scale,
Could take the size of pots of ale;
Resolve, by sines and tangents, straight,
If bread or butter wanted weight;
And wisely tell what hour o' th' day
The clock does strike, by algebra.

Butler's Hudibras.
