318 and a copy of it in Cornell University Library bears the inscription "Ex dono Authoris Octob: 22º 1665." No further edition was published during Graunt's life, but in 1676 a fifth edition was put out, it is said under Petty's supervision. To this, the completest edition, here reprinted, there were added "Some further Observations of Major John Graunt." Since 1676 the Observations have been printed but once in English, viz. in A Collection of the Yearly Bills of Mortality from 1657 to 1758, London: 1759, which speaks erroneously of "the sixth edition, in 1676." There is also an anonymous German translation published at Leipzig in 1702.

Concerning the disputed authorship of the Observations see the Introduction. No MSS. of the book are known.
