Abstract
THE first attempt to prove Fermat's last theorem contained in this edition repeats a fallacy to which attention has already been directed in NATURE, Oct. 30, 1919. On pp. 18, 21, “quantities”t and υ are defined, and it is assumed that these quantities are integers, which is not generally the case. In the second attempt there is a fallacy, pp. 34—35, relating to the divisibility of numbers. The pamphlet ends with a version of Barlow's attempt to prove the last theorem, taken from the 1811 edition of his “Theory of Numbers.”Barlow's attempted proof contains a well-known fallacy, which need not be pointed out here.
