[April 



The Iiislrunicnts with which the foregoing ob'orvafions nro tnnde, iire 

 phioed in tlie Western Verandah of the Honourable Company's Obser- 

 vat- rv : me about 5 feet above the surface of the ground, and 27 feet 

 above the level o^ the Sea. 



The barometer »>mj)loved is No. 1, one of two Sland.mls which I had 

 constrnoted at tlie end of the year IS3G, to supply tlic place of those 

 broktn during the slorni ; the indications set down are those iinniediate- 

 ly read olf frou) the instrument, and consequently r»-quire in addition 

 to the ordinary correction for temperature, the correction -\-,05l i\>v 

 capillarity: from a late comparison of these wiih a m.ignilicent standard 

 by Newman which had been constructed with all the advantages of 

 modern improvement for the Trevandraai Obiesvatory, it appeared that 

 when corrected for capillar ihj, the 



Trevandiuni ^Standard stood at , .30,000 inches. 



the Madras No. 1 30,001 do. 



No. 2 29,yy3 do. 



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

 72° (the only point at which a comparison has been made) it was found 

 to difter insensibly from the Royal Society's Standard:
