One Autograph Letter Signed, one Typed Letter Signed, one Autograph Note Signed and one Typed Note Signed (all 'E. N. da C. Andrade'), to G. K. Menzies (3) and K. W. Luckhurst (1), Secretaries, Royal Society of Arts, with carbon of one reply.

All items good. Two bearing the Society's stamp. Item One (typed note, 15 October 1931, 4to, 1 p): He is sending 'short summaries of the two lectures, in a form which I prefer to mere headings'. Item Two (autograph letter, 17 January 1932, 8vo, 1 p): He is sending 'summaries of the two lectures'. 'As you seemed in a hurry I have not waited to have them typed. I think that they are legible, but I will look at a proof if you like.' He has left it to Menzies 'to add any preliminaries or conclusions that may be necessary'. Item Three (autograph note, 14 June 1933, 4to, 1 p): 'Please see and return.' Item Four (typed letter, 16 June 1948, 4to, 1 p, 22 lines): He is returning 'Mr. Jacob's paper [...] of end corrections of pipes'. 'I rang up your office last week and explained that it was out of the question for Mr. Jacob to read a paper before the Royal Society. Papers read before the Royal Society are a small selection from those which have been accepted for publication and there is no chance of Mr. Jacob's paper being accepted for publication.' He is not saying 'that the matter of the paper does not possess value', but 'it is not set out in a form that would be acceptable', and 'it requires rewriting by somebody of experience in these matters'. 'Personally I must make it quite clear that I have no time for matters such as these, much as I regret to seem churlish. I should also like to make it more than clear that my name must not in any way be mentioned to Mr. Jacob. I have already more letters from gentlemen unknown to me who would like me to do odd jobs for them than I can possibly cope with.' Item Four is accompanied by a carbon of Luckhurst's apologetic reply: 'as Mr. Jacob is known to me personally and has been a Fellow of the Society for 25 years, I felt I ought to do what I could to help him. Being a layman in scientific matters, I naturally sought the most expert [sic] advice.'
