    attempts at their improvement; but which attempts, UQControlled by any definite principle, have left the matter scarcely less enveloped in obscurity than it was a century ago. Indeed the introduction of some additional tables, professing- though constructed in defiance of Nature's laws — to advance our infor- mation as regards the gradual waste of life, create greater embarrassment, consequent on such accession of discordant and contradictory results. The object is, now, to provide a remedy for those deficiencies. Many fundamental questions,—• relating to the average term of life,—to the comparative rates of mortality at specific years of age,—and generally to all movements of the population in its progress of renewal,—are however so complicated, from their subordination to local or transient circumstances, that the researches in this branch of science encounter endless impediments. Its having devolved on myself, to fathom those questions and strive against their incessantly recurring difficulties, should be imputed to the absorbing avocations of men more eminently gifted; which prevented their anticipating me. Perhaps some may have abstained, on considering the extent of sacrifice required for the completion of so arduous an enterprize. Let no one therefore suppose that
