Brief correspondence chiefly regarding Nicholson's resignation from the Council (one letter concerns arrangements for the Society's 1970 Conference at which Nicholson gave a talk); incomplete typescript inscribed in Nicholson's hand 'SPNR History author & publ unknown date after 1980', with his revisions and annotations. On the backs of two pages of the latter is a manuscript draft of a letter by Nicholson to Hans-Rudolf Kuhn (C.G. Jung Institute), apparently unrelated to the SPNR, inscribed '?1996'.
