Mr. King’s modesty has been so far overruled as to suffer us to
communicate these his excellent computations, which we can the more
safely commend, having examined them very carefully, tried them by some
little operations of our own upon the same subject, and compared them
with the schemes of other persons, who take pleasure in the like studies.
What he says concerning the number of the people to be 5,500,000 is no
positive assertion, nor shall we pretend anywhere to determine in that
matter; what he lays down is by way of hypothesis, that supposing the
inhabitants of England to have been, A.D. 1300, 2,860,000 heads, by the
orderly series of increase allowed of by all writers they may probably be
about A.D. 1700, 5,500,000 heads; but if they were A.D. 1300 either less
or more, the case must proportionably alter; for as to his allowances for
plagues, great mortalities, civil wars, the sea, and the plantations,
they seem very reasonable, and not well to be controverted.
Upon these schemes of Mr. King we shall make several remarks, though the
text deserves much a better comment.
