|Copy letter from Robert William Frederick Harrison, to A Spencer Bower, Avenue Road, St Neots, Hants
|21 September 1905
|Acknowledges Bower's letter of the previous day addressed to Professor [Joseph] Larmor, enclosing a paper on a method of cutting a triangle so as to form another triangle of some predetermined different shape, which Harrison will show Professor [Joseph] Larmor when he is next here. Mr Dudeney did not read a paper before the Society on the subject of triangles, all that he did was to exhibit at a Soiree some models showing the method of cutting triangles to form squares. Also no paper can be received for consideration unless it is communicated by a Fellow.
