Atmospheric Pressure and Cholera in India

This paper is concerned only with British territory in India. The records of Native States iire scarcely sufficiently reliable to be made use of. The materials available are somewhat imperfect. Death registration is rather uncertain, and mortality is our only measure of intensity of an epidemic. The weather observations, too, are not always as accurate as they might be. By these irregularities a connection,"however close between cholera and the weather, must at times appear strained and interrupted. But in spite of all this the extreme length and regularity of some of the larger oscillations affecting weather elements reuder India peculiarly suitable for the study of the meteorology of disease.
