The mean temperature of the year was reduced several degrees from former years, in consequence of the 

 whole of the observations for the hot months having been made in the Hill Fort of Hurreechunderghur in the 

 Western Ghats, at an elevation of 3943 feet above the level of the sea. The weather also during the Mon- 

 soon was cooler than usual.
