Dr Thomas Birch is commonly regarded as the editor of this Collection. Cf. Ogle's Inquiry into the Trustworthiness of the Old Bills of Mortality, in Jour. of the Stat. Soc iv. 442; Dict. of Natl. Biogr., s. v. Birch. But James Milne, writing about 1824, says, upon the authority of Dr William Heberden, the younger (1767—1845), that "the bills were collected into a volume by his father, the late Dr Heberden [1710—1801]. He procured likewise observations from several of his friends, rectors of some large parishes, or others likely to give him information; particularly from Bishop Mess, Bishop Squire, and Dr Birch. These, together with some of his own results, were thrown into the form of a preface; and the whole was committed to the care of Dr Birch. To make the calculations which appear at the end of the book, Dr Heberden employed James Postlethwayt, Esq., a very distinguished arithmetician."
