The Instruments with which the foregoing observations are made, are 

 placed in the Western Verandah of the Honourable Company's Obser- 

 vatory ; at about 5 feet above the surface of the ground, and 27 feet 

 above the level of the Sea. 



The barometer employed is No. 1, one of two Standards which I had 

 constructed at the end of the year 1836, to supply the place of those 

 broken during the storm : the indications set down are those immediate- 

 ly read off from the instrument, and consequently require in addition 

 to the ordinary correction for temperature, the correction +,051 for 

 capillarity : from a late comparison of these with a magnificent standard 

 by Newman which had been constructed with all the advantages of 

 modern improvement for the Trevandiuin Observatory, it appeared 

 that when corrected for capillarity^ the 



Trevandrum Standard stood at 30,000 inches.

No. 2 ,...29,993 do. 



The thermometer was made on purpose for the Observatory, and at 

 75° (the only point at which a comparison has been made) it was found 

 to differ insensibly from the Royal Society's Standard :
