Publication date range suggested by Wing; presumably based on the identification of the bookseller as the Thomas Passinger who was active in London 1664-1688; it is also possible that the imprint refers to Thomas Passinger's nephew and heir, Thomas Passinger [sic] the second, who was on London Bridge from 1692-1695. See Plomer, Dictionary, 1668-1725.
