ABSTRACT
Very early I had interested myself in the problem of density of population as affecting the death-rate (p. 139); and in 1891 I read a paper before the Royal Statistical Society on "The Vital Statistics of Peabody Buildings . . . " embodying my conclusions. In prefacing this contribution I explained that I had undertaken to write on "the relation between density of population and mortality," and to review Parr's almost axiomatic statement on this relation, explained on page 301. For this purpose I had obtained the statistics of the Peabody Buildings as an extreme instance of a dense population, "an instance which did not exist at the time when Dr. Farr first showed the close relationship then existing between density of population and mortality, and evolved his formula from it."
