Letter from Edward M [Mann] Langley, 48 Waterloo Road, Bedford, to 'Dear Sir' [Charles Taylor?] He has not noticed and errors or misprints in E.G.C., but he has not been doing geometrical conics recently, except in problem brought by pupils. He thinks that an insertion of a section on [Gaspard] Monge's method application in Descriptive Geometry would be useful. The methods are coming into theoretical curves, but are banished in England from practical geometry books. Langley offers to write short pieces. He is free of school in ten days. He discovered a mass of Brook Taylor correspondence after publishing a facsimile letter, describing the material, and noting that he told Dr. [Joseph] Larmor about it. 10 December 1907
