Sir Everard's article appeared as pp. 157-178 of the Philosophical Transactions of the Royal Society for January 1799, but this is a separately paginated offprint (in other words not simply excised from the journal printing). Offprints like this were usually provided to the author to distribute privately, and like this example can be rare today.
