no marked deviation is observed. Its mean annual rainfall is the same as that for 

 Cawnpore. 



The minimum temperature coincides generally with the minimum cholera, but 

 the reverse does not hold good. Here, again, the month of minimum pressure corresponds 

 with the maximum of cholera.

(b) Selected stations in Rajputana, Bundelcund and the Central Provinces. 



(1) JMoRAR, Jhansie, Saugor. 



Before pushing up any further towards the north-west a few words may be said 

 regarding some of those stations included in our list, such as Jhansie and Morar, occupying 

 those large alluvial tracts (with black cotton-soil) which spread out from Agra towards 

 Gwalior and southwards. 



Of the 726 cases of cholera which have occurred among the troops in Morar 

 during the 17 years of which records exist, 438 have occurred during annual visitations 

 in the month of August, and 90-2 per cent, of the total during the rainy season. At 

 Jhansie^ again, of the 166 cases recorded during 22 years, 99*4 per cent, occurred 

 within the same seasonal period, 134 being in the month of August. The Jhansie 

 rainfall returns have been adopted for both stations, according to which July and August 

 are the rainiest months, 12 inches falling in the former and 9 in the latter. 



The cholera-history of Saugor also — 150 miles to the south — is practically the 

 same, August again taking the foremost place, the next months being October and 

 September, followed by May, with 30 cases against 88 in August.
