There is a collection of 21,000 specimens in the RSM (accession no. 1962-24) collected from about 1916-1938. Incorporated into the collection is that of H.Heasler whose specimens were nearly all remounted and re-labelled by May but bear initials HH. Most of these date from up to 1903. Also includes specimens from other collectors including E.A.Newbery, P.H.Harwood, H. Donisthorpe, and A.Ferguson.. The origin of other specimens labelled ‘Old Coll’ and ‘D’s Box’ is obscure. The collection was given by Frank Balfour Browne who had previously acquired it as an anonymous Glasgow collection, and in keeping it for himself said that he considered it of not sufficient quality for an institutional collection and used it to make slides, dissections, etc. Its identity was established by Pelham Clinton who noted that Kevan considered it rather important and that it included several things new to the British /Scottish (?) list The only references to May seem to be those by J.J.Walker: ‘Sheppey records of A.H.May’ in Trans.ESL, 7(2), 1932, p.123 and by A.Fergusson: ‘Clyde records of A.H.May’, in Scot Nat., 1922, pp.155-164.
