In this paper the factorization of arithmetical numbers of the form , where x; is a rational number such that kx is a perfect square, is investigated by means of a trigonometrical transformation. The number k will be taken to be prime for the present.

page 67 note * See the author's question in the Educational Times for June 1898. Numbers of the form x 4n+2+l have been called Bin-Aurifeuillians by Lt.-Col. Allan Cunningham, R.E., who has dealt with them in a paper “On Aurifeuillians” in the Proceedings of the Lond. Math. Soc., Vol. XXIX. (03 1898).Google Scholar My acknowledgments are due to Lt.-Col. Cunningham for his kindness in allowing me to draw on this paper and on his solutions in the Reprints from the Educ. Tim. for most of my illustrative examples.
