Dear Museum-Lers Stevens of Covent Garden, London were the dominant force in natural history and ethnography auctions in Great Britain for over 100 years. I am writing a precis of the STevens involvement in this business for the New Dictionary of National Biography and am interested in finding the whereabouts of sale catalogues and any other memorabilia / archives / etc. My starting points have been Chalmer-Hunt's invaluable "Natural history auctions" and ALlingham's "Romance of the Rostrum." I know there are many auction catalogues and sales that did not make it into C-H's compendium (I have found several of them myself) and I would be very interested to hear from any one knowing of the whereabouts of catalogues or the dates and other details of sales not listed or incompletely listed therein. I would be particularly interested to hear of catalogues of the sales of the stock or collections of James Tennant, mineral dealer and Prof. of Geology at King's College (1818-1881; at least 12 sales 1881-82 and no catalogues known to be extant); and John Calvert, gold-miner and con-man (1825-1897; 5 sales 1897-98).
