Letter from [Arthur Crossley], Secretary of the Chemical Sub-Committee, to H M Elder Has been given Elder's name by J P Millington as 'one who would be willing to undertake the preparation of somewhat out-of-the-way chemical substances which have previously been prepared in Germany' -- would like to discuss the matter but thinks this may be impossible -- would like to have an idea of 'the operations that you will undertake, and of the plant which you have available'. 15 June 1915
