84 CLIMATE. 



" The hottest months of the year are March, April and 

 May ; the coldest months December, January and February. 



" The extreme average range, between day and night tem- 

 perature, was, about the same as the extreme annual range, 

 or 21'150. The mean daily range for the whole year (from 

 7 years' observation), was 16" 17 degrees.* 



" The observations, however deficient in extreme accuracy, 

 separately, all concur in their results, and they may there- 

 fore be admitted as tolerably well established." 



The following observations on all the tables in the ap- 

 pendix, taken together, will be read with interest. 



" From the tables of temperature on the hills, it will appear, 

 that the mean temperature of the year, the mean maximum, 

 and mean minimum, bear about the same relation to each 

 other, as in England, but are about 10° degrees higher, while 

 the daily range is somewhat less. The highest observed 

 temperature, and the lowest in England, are greatly above 

 and below, respectively, the corresponding points on the Neil- 

 gherries, that is to say, the extremes are greater. 



" The power of the sun's rays, another most important point 

 in estimating the effects of exposure, is, also, considerably less 



* As far as published observations enable a comparison, the follow- 

 ing gives the extreme ranges of the mean monthly temperature of 

 several Indian Hill Stations.
