Excerpt from Quarterly Journal of the Royal Meteorological Society, 1891, Vol. 17 For the purpose of illustrating the influences of ground water upon health I propose to deal more especially with the records of Croydon; not because Croydon is an exceptionally unhealthy district, for it is a district extremely favourable to health by reason of the comparatively recent extension of its population over a maiden soil which has not had time to be polluted by the residence of man upon it. In fact, if you wish to get the true significance of the bearing of climatic influences on health, you must go into those districts which have been long occupied by man as residences, in which the ground has received from year to year considerable accessions of pollution. On this account the observations made at Croydon are unfavourable, but what occurs there is accentuated in other districts not so favourably located. We have, moreover, in Croydon a comparatively perfect register of Baptisms and Burials, going back to the year 1589.
