Copy letter from James Hopwood Jeans, Secretary of the Royal Society; to D. Morgan Esquire; 4 Leghorn Road, Willesden Junction, N.W. Acknowledges receipt of Mr. D. Morgan's communication in which he claims to have a Euclidian method for the trisection of any angle. Informs him that no paper can be received by the Royal Society unless it be communicated by a Fellow, and notes that to trisect an angle by purely geometrical methods is generally considered by mathematicians to be impossible. 28 April 1921
