40 Hyderabad, however, in marching back through the Kurnool District in January 1871, suffered from cholera, and communicated it to several villages in which they had encamped. This party had travelled from Trichinopoly to Ghooty by railway. The Kurnool District, until this outbreak, had been absolutely free of cholera for more than eighteen months. 63. TANJORE.-As in the Trichinopoly District, the various talooks were not equally affected by the cholera epidemic. The talook of Combaconum suffered more than any others, and this particular talook includes some of the most plenti- fully watered lands in the whole district. In the month of January two-thirds of the population of this talook were exposed to cholera influences, while in other talooks the proportion was generally much less. The talooks of Tanjore, Negapa- tam and Manargoody, also well-watered districts, had a heavy cholera morta- lity. The Municipal town of Combaconum had cholera deaths in every month of the year ; the situation of the town, between two great branches of the Cauvery river, and the fact that the sub-soil water of the whole country rises and falls with the streams, would, according to Pettenkofer, yield the necessary conditions for the development of cholera. Observations are now being made in this locality to register the rise and fall of such sub-soil water, in connexion with the mortality from cholera. The total deaths in the district were 4,563, and the proportion of cholera mortality to population in the various registration circles was as follows :- Table Showing Proportion of Cholera Deaths to 1,000 of Population in each Talook, &c., of the Tanjore District, in each month of the year 1870.
