m *> ON THE HEIGHT OF THE 



Barometrical meafnrements, though lefs to be depended upon 

 fehan a geometric one, would have been defirable as mowing that no 

 ivery material error has by any overfight crept into it. In the abfenee 

 of any obfcrvations of the barometer on the nearefl acceflible heights, 

 we are in pofTtnaon of forne made on fummits of mountains belonging 

 to the intermediate chain. ,Eor indance, at Chifdpdni fort on the 

 route from North -Bihar towards <* Cai'hmdndu in Nepdl t the ba- 

 rometer was noted on two days at an interval of more thin a month 

 (23d February and 28th March 1793,) andsboth obfcrvations gave the 

 fome length of the column of mcrpury 24.63. On one of thofe 

 days the barometer was.oblVjrved at a fpot a Lttle more elevated, near 

 the cold fpring which gives name to the place,* 24.43 : anc ^ tne tempe- 

 rature mown by the -thermometer is alfo given, 65' Fahrenheit's fcale 

 at 9 o'clock, and 6 r /° at 1 1 in the forenoon. + A meteorological jour- 

 nal was kept by Dr. F. Buchanan at CaChmdndu, for nearly ten months 

 (April 1S02 to February 1803,^ and the mean height of the baromeer 

 in that period is 25. 2. 'The greatett height being (in May) 25.6V; 

 and the leaft (in Auguft) 24.834 On a minute in fpeaion of it, the 

 changes, though obfcrvations -were made at four different hours of eacla 

 day, are fmall, feldom amounting to the tenth of an inch withia.'the 

 day, and by no means correfponding to the changes of temperature 

 (hown by the thermometer.
