Copy letter from Herbert Rix, to Dr Henry Clifton Sorby, Fellow of the Royal Society 'Dear Sir, The exhibitor of the "New Photography" last Thursday was Professor Silvanus P. [Phillips] Thompson, Principal of the City & Guilds Technical College, Finsbury. I daresay he can give you some specimens of it. Mr Swinton whose photos. you say you already have, is the only other man I know of who is likely to have successful examples to lend. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 4 February 1896
