It may appear to many that the result of all these observatins on conditions of soil is not commensurate with the time and labour expended in obtaining it. In so far as arriving at any definite determination of the influence of soil-condi- tions on health is concerned, the results as they stand at present are, no doubt, not so conclusive as might be desired. It is only on prolonged and continuous observations in various localities that definite conclusions can be based.

It has, no doubt, been known for a long time that the ordinary course of cholera in Calcutta was simi- lar to that shown in this Report, and that the prevalence of the disease was related to local conditions of season; but in regard to this phenomenon, attention has hitherto been almost entirely directed to the conditions of atmospheric meteorology, and this is almost the first attempt which has been made to ascertain whether any definite relations exist between the prevalence of the disease and special telluric phenomena. We believe that the present observations, although confined to a very limited period, may serve a good purpose in attracting attention in this country to the importance of the subject and to the desirability of obtaining data The observations in Calcutta may ie_,aidm0 it. *We ha\e, m so far as our own w rk aociniay^er've'attract^rte^tion is concerned, by their means obtained standards of to the subject. comparison which will be of very great value in examining the conditions of soil present in other localities during the pre-](https://iiif.wellcomecollection.org/image/b24906621_0026.jp2/full/800%2C/0/default.jpg)
