Clements tentatively attributes this stamp to “How”. The crest of a wolf's head erased covered in ermine spots is ascribed in Fairbairn's Crests to a number of possible candidates: Adams of London (ermine); Barton (ermine); Booer or Bower of London (ermine); Richard How, son of Sir Richard How, Alderman of London, granted 1691 (pean); Kenerby (ermine); Maingy or Mainguy of Guernsey (erminois); and Rush (ermine). Of all possible charges a wolf's head erased is one of the most difficult to identify, being easily confused with a tigre's, griffin's, fox's, greyhound's or even a boar's head. In the case of Adams of London, it seems likely that the crest is in fact a tigre's head. That leaves six possibilities, assuming that the family appears in Fairbairn. There is very little evidence to help one choose among them. Perhaps the most hopeful line of enquiry is through the published lists of known book collectors and of book sales. Clements examined the catalogue of Richard How's sale at Sotheby's 3 March 1890 for Bray’s Evelyn's Memoirs illustrative of the life and writings of John Evelyn and also for Hooker. Pomona Londinensis, but did not find either. He also noted that Hazlitt in his Roll of Honour includes Hows of Apsley Guise in Bedfordshire as a book collector.
