The Instruments with which the foregoing Observations are made, 

 are placed in the Western Verandah of the Honorable Company's 

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

 feet above the level of the Sea ; the Thermometer was made on pur- 

 pose for the Observatory, and at 75 (the only point at which a compa- 

 rison has been made) it was found to differ insensibly from the Royal 

 Society's Standard the Barometer is one of two Standards which I 

 have lately constructed, and may be depended upon to 0,01 of an inch.
