The Instruments with which the foregoing observations are made, are 

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

 vatory ; at about five feet above the surface of the ground, and twenty- 

 seven feet above the level of the Sea ; the thermometer was made on 

 purpose for the Observatory, and at 75° (the only point at which a com- 

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

 Society's Standard | the barometer is one of two Standards which 

 have been lately constructed, and may be depended upon to 0,0100 

 an inch
