The portion of the ensuing Tale relating to the Grocer of Wood-street, and his manner of victualling his house, and shutting up himself and his family within it during the worst part of the Plague of 1665, is founded on a narrative, which I have followed pretty closely in most of its details, contained in a very rare little volume, entitled, "Preparations against the Plague, both of Soul and Body," the authorship of which I have no hesitation in assigning to DEFOE. Indeed, I venture to pronounce it his masterpiece. It is strange that this matchless performance should have hitherto escaped attention, and that it should not have been reprinted with some one of the countless impressions of the "History of the Plague of London," to which it forms an almost necessary accompaniment. The omission, I trust, will be repaired by Mr. HAZLITT the younger, DEFOE'S last and best editor, in his valuable edition of the works of that great novelist and political writer, now in the course of publication. It may be added, that a case precisely similar to that of the Grocer, and attended with the same happy results, occurred during the Plague of Marseilles, in 1720. For my acquaintance with this narrative, as well as for the suggestion of its application to the present purpose, I am indebted to my friend, Mr. JAMES CROSSLEY, of Manchester.
