The contents are as follows. (i) Fragments of diaries, 1960-1974, undated (folio 1); (ii) Letter to Ruth Ziegler, 1976-1977 (folio 9). Ruthven Todd began this as a letter, but it developed into a long document, partly a detailed record of his daily activities for two months, and partly rambling reminiscences. Folios 44-48 and 57-60 are photocopies.
