as to the cause of this exemption, when its isolated and exposed situ- 

 ation in the Peninsula is considered. Upon this and other points of 

 interest connected with the meteorology of these Hills much light 

 will doubtless be thrown by the observations now regularly conduct- 

 ed in an observatory recently erected on Bodabetta under the aus- 

 pices of Mr. Taylor, the H<)norable Company's Astronomer at Mad- 

 ras, in which an instrument for measuring the force of the wind, and 

 other valuable adjuncts to a meteorological Observatory have been 

 placed. 



During the prevalence of the S. W. monsoon the atmo&phere is 

 almost continuously charged, more or less, with dense mist, enveloping 

 -chiefly the mountain tops, but descending into the inhabited vallies 

 as the warmth of the day passes, and spreading in heavy and impal- 

 pable fog in all directions. When not under this influence the at- 

 mosphere overhanging these mountains is brilliantly clear and cloud- 

 less — and especially so on the eastern side of the range.
