ABSTRACT
It has been shown in the general analysis of the returns from the whole kingdom, that cholera has not only been most fatal in the low, and least fatal in the high parts of the country, but that the fatality has diminished proportionably as the dwellings of the population have been raised above the sea level. The epidemic began and was most fatal in the ports on the coast; and in ascending the rivers step by step, we saw it grow less and less fatal. It became probable that a certain relation existed between elevation and the power of cholera to destroy life. The more exact information which we possess respecting the London districts establishes this connexion beyond doubt. The relation may not be expressed by the same figures in other places, or in London at other times, but it will always be the general rule that the mortality of cholera is inversely as the elevation of the people assailed above the sea level.
