There are two items of correspondence dated January 1962 between Wilkinson and R. Brown of the Ipswich & East Suffolk Hospital regarding a specific named case of pernicious anaemia that was treated with Hydroxocobolamine with details of his resultant blood count and sending a second specimen to Wilkinson for serum B12 estimation.
There are also two items of correspondence from J.J.F. Merry of Merck Sharp & Dohme Ltd. dated June and August 1961 regarding their new product Hydroxocobalamin, which they hope will give longer therapeutic blood levels than existing preparations and sending Wilkinson supplies of it for a comparative study with cyanocobalamin.
