CSAC. 25/2/75 Description of the collection The papers, which cover the years 1910 — 1951, were received from Mrs. Chaundy. They consist almost entirely of lectures on mathematics delivered in the University of Oxford. with a view to publication (see items 25~—32). Some have annotations and revisions, perhaps Chaundy kept the lectures in files with his name and address and usually a date; he classified them by a letter and subscript numeral. The alphabetical sequence has been retained, although it does not correspond with chronological order; work classified under one letter group may span several years, while incomplete sequences (e.g. *Bt or 'N') appear to indicate that some lectures are missing. contained loose notes, calculations or correspondence; these have been extracted and appear as separate items immediately following the relevant file. Some files Unless otherwise stated, all items are manuscript. Titles in inverted commas are those on the manuscripts. Advice on identification and technical terms was kindly given by Dr. Peter Collins, Fellow of St. Edmund Hall, Oxford.
