for which we are indebted to the eminent physicians who have resided in those districts, in example of which we have only to refer to those of Chester by Dr. _Haygarth_,[226] of York by Dr. _White_,[227] while from the returns of Northampton Dr. _Price_ computed his celebrated tables of the probabilities of life, and in a curious memoir read before the Royal Society he advances strong reasons for believing that there is a prodigious preponderancy in favour of the country above the most healthy cities.[228] We shall conclude this subject with observing, that the metropolitan bills establish beyond all doubt the gratifying fact of the superior healthiness of London, notwithstanding its increase of population, in the present day to what it was during the seventeenth century, when the deaths exceeded the births, by more than one half of the whole number; while in the present age, the sum total of births exceeds that of deaths; the same improvements have taken place also in the provinces, and we are borne out by the concurrent testimony of our best political arithmeticians, in the assertion that the value of human life is increasing in Great Britain, while the diminution in the number of certain diseases, and the total extinction of others, offer the surest proofs of the general amelioration that has taken place in our national habits and manners.
