been accumulated. July holds the highest position as to prevalence of the disease in this 

 station also, 74 of the total cases having occurred then ; but it should be noted that 68 

 of these cases occurred in the July of one year, viz., 1865. The next highest month of 

 cholera-prevalence is March, furnishing 57, 48 of which are due to two annual visitations 

 during the 21 years, 24 cases in 1856, and 24 in 1864. The jail has been visited by 

 cholera six times during July, five times during March and August. No cases have 

 occurred in December and January, and only one each in February and November. 



The foregoing data, however, are far too limited to enable a correct estimate to be 

 made of the seasonal prevalence of the disease in the district — a district which is par- 

 ticularly important in the study of the question of the causation of climatic diseases, 

 seeing that it occupies a somewhat peculiar position as to monsoon influences. Mr. 

 Blanford describing the rainfall of these parts writes : " All through the Mahratta Country, 

 as far as Nagpore, the annual distribution of rain is the same as at Bombay, ^.e., practical^ 

 restricted to the season of the summer monsoon. But from Nagpore eastwards spring 

 storms are not infrequent, and an appreciable amount of rain falls during the earlier 

 months of the year."* 



With the object of still further illustrating the cholera of the Central Provinces 

 according to seasons, we again avail ourselves of the proof-copy of Dr. Townsend's report 

 regarding the epidemic of 1875-76, and incorporate the data regarding the cholera 

 mortality of Nagpore in the same manner as was done regarding Jubbulpore. The 

 prevalence of the disease in the district during the epidemic according to months will be 

 found in the following table, as also the monthly distribution of the disease as it has 

 occurred in the Nagpore Jail during the last 21 years.
