Latitude of the Observatory, 53° 24' 48" N. ; Longitude, 3° 0' 1" W. Cistern of the Barometer elevated 

 87 feet above the mean level of the Sea. 



The Meteorological observations which have been taken at 

 the Liverpool Observatory now extend over a period of five 

 complete years, and the whole of these observations have been 

 reduced on one uniform plan. The mean and extreme values 

 have been deduced with great care, and the monthly and yearly 

 changes which have taken place in our atmosphere, during the 

 above named period, have I believe been traced with very great 

 accuracy in the accompanying tables. 



The instruments with which the observations have been 

 taken were all made by Mr. Adie, of Bold-street, Liverpool. 

 They consist of a standard barometer of Neuman's con- 

 struction, the tube of which is nearly an inch in diameter ; a 

 maximum thermometer, and a minimum thermometer of 

 Rutherford's construction; a rain guage of Howard's con- 

 struction ; and a pair op wet- and dry-bulb thermometers 

 having a scale of about one tenth of an inch to a degree.
