The problem is

Between two sides of a triangle to inflect a straight line which shall be equal to each of the segments of the sides between it and the base.

This problem was brought before the Society at the January meeting in 1884, and a solution of it by Mr James Edward will be found in our Proceedings, Vol. II, pp. 5–6, a second by myself in Vol. II., p. 27 (10th April 1884), a third by Mr R. J. Dallas in Vol. III., pp. 41–2 (9th January 1885). Solutions of a slightly more general problem were also given by myself in Vol. III., pp. 40–1, and reference made to the Educational Times, Vol. 37, p. 328 (1st October 1884), and to Vuibert's Journal de Mathématiques Élémentaires, 9e année, p. 45 (15th December 1884).
