36 Exempted tract-Cholera of 1869. Districts. Population for which returns were received. January. February. March. April. May. June. July. August. September. October. November. December. Total.

And the same observation holds good in regard to Tinnevelly District, in which only 80 out of 21,808 registered deaths are noted as due to cholera. The Madura and Tinnevelly Districts with the Western Coast Districts (including the Native territories of Travancore and Cochin) may be safely declared an "exempted tract," so far as the cholera invasion of 1868-69 was concerned. Salem and Coimba- tore. 57. The districts of Coimbatore and Salem suffered in 1869 to a very limited degree from an importation of cholera from the North Arcot District to the eastward, in the month of September. The particulars of the importation, so far as they could be ascertained, are recorded at page 17 in the Cholera Report of 1869, and the following table shows the monthly distribution of cholera in 1869:- Districts. Population for which returns were received. January. February. March. April. May. June. July. August. September. October. November. December. Total.

Northern Districts. 58. We have yet to take cognizance of the condition of the northern districts on the Eastern Coast in regard to cholera, and then the survey will be complete up to the beginning of 1870. Ganjam. The Ganjam District abuts on the area mapped out by Bryden as the district of endemic cholera, and it is undoubtedly true that it suffers in common with the endemic district, as regards time and season, but although invasion of the southern districts along the Eastern Coast appears to have taken place in the epidemic of 1818, it has not been so, accord- ing to my knowledge, on any other occasion of an invasion. During 1869, it is a remarkable fact, that the influences invading from Ganjam southward, stopped abruptly somewhere in the Vizagapatam District, the southern boundary of which was not overstepped as will be seen in the following table:-
