Borrowed Thoughts

Mr. SINGER (Vol. i., p. 482.) points out the French original from which Goldsmith borrowed his epigram beginning— "Here lies poor Ned Purdon." I find, in looking over Swift's works, a more literal version of this than Goldsmith's:— "Well then, poor G—— lies under ground, So there's an end of honest Jack; So little justice here he found, 'Tis ten to one he'll ne'er come back." I should like to add two Queries:—Who was the Chevallier de Cailly (or d'Aceilly), the author of the French epigram mentioned by Mr. Singer? And—when did he live?
