Trinity College, Cambridge. - Goldstein's paper for the CPS [Cambridge University Physics Society] has been sent to Hardy by Hodge, and Hardy 'inevitably began playing about with the integrals'. Has no criticisms of Goldstein's 'way of dealing with them - it is straightforward and effective', but 'the following formal connections' may be of interest to him. Extensive mathematical notation and discussion follows, and the end of which Hardy concludes 'So your way of attacking the integral seems, in practise at any rate, much better than mine'. In a postscript he adds 'Some of your formulae set nasty problems for the printers', and suggests some changes.
In pencil; written on the back of what seem to be proof sheets for a mathematical paper by Hardy. Envelope addressed to Goldstein as 'Dr S. Goldstein, National Physical Laboratory, Teddington, Middlesex' and postmarked 'Cambridge 5 15 PM 1 Feb 1944'.
