Evans's intellectual vigour and spirit of enquiry remained undiminished to the end of his very long life, as can be seen from several surviving letters written after he was ninety. He was fully conscious of his continuing achievements in extreme old age, and nurtured them by a regime of outdoor exercise, careful diet and self-imposed limits on social activities. As the years went by, however, he realised the need to make suitable dispositions of his possessions; scientific books and journals were offered to appropriate institutions, and in 1964 Evans made a selection of personal writings, photographs and other material which, in bound or typescript form, he circulated among his family and friends: these appear at A.3, A.6 and C.6 in the present collection. It seems that he then destroyed his remaining papers; consequently, no personal records survive of his most important research findings, or of his consultative work for government and industry in the earlier part of his life, and the existing documents are essentially confined to those which accumulated after this major clear-out in the 1960s.
An exception to this is the material relating to Evans's tripartite consultancy with S. Rideal and his son E.K. (later Sir Eric) Rideal in 1912 (see B.2 - B.5). The remaining material in Section B has its interest in documenting Evans's lifelong concern - no doubt continuing that of his father Richardson Evans - for the conservation of the natural environment, whether by the use of windmills to replace or supplement fossil fuels, or by his somewhat less than practical scheme to foster economical and nutritious home baking which greatly occupied his time and tea parties in his last years (see B.17 - B.31 and introductory note).
Several of the letters in Section D refer to the considerable achievement of his publication in 1976 of the 'Second Supplementary Volume' of his major book 'Corrosion and oxidation of metals'. He was then eighty-seven, but continued to ask his correspondents for comments and additional references which he was assembling for use by a successor who would after his death compile a third supplement.
