Presentation copy inscribed, dated (22 April 1968) and signed by the author to Sir Walter Crocker. Loosely inserted is Crawford's later article 'The School of Prudence or Inaccuracy and Incoherence in Describing Chaos?' (reprinted from Historical Studies, Volume 15, Number 57, October 1971), wrappers lightly creased and a little sunned about the spine. Also loosely inserted is Crawford's obituary of John Cawte Beaglehole, O.M.; being four single-sided leaves rough-cut and stapled at the top left corner. Crocker appears to have added a mysterious question mark at one point .
