Abstract
PROF. C. V. BOYS, in his letter “A Puzzle Paper Band” in NATURE of June 9, p. 774, gives scant credit to the geometers. Forty years ago they described the endless band of paper with a half-turn twist in it, and found that if cut down the middle line it gave a single endless band with four half-twists. But they were so obsessed, he says, with the consequence of cutting down the middle line that they missed the result he now describes. This consists in taking a band with four half-twists and converting it by manipulation into a half-twist band of double thickness.
