The accompanying paper is a Meteorological Journal, 

 shewing the maximum and minimum points the Thermome- 

 ter indicated, the Height of the Barometer, and the Amount 

 of Rain. 



The first column gives the thermometric results ; the 

 second gives the barometric pressure, in inches and thou- 

 sands of an inch; the third gives the amount of rain that 

 has fallen, in thousands of an inch. These observations 

 have been made as nearly as possible to 10 o'clock, a. m., each 

 day throughout the past year. They are tabulated each 

 month, so as to shew the quantity of rain that has fallen 

 during that period. Twelve months are then made up, 

 which shews the year's rain to be 23.440 inches. 



It may not be out of place to mention the description of 

 instruments which were made use of on the occasion. 



The temperature was observed with a pair of Dr. Ruther- 

 ford's self-registering thermometers. The barometer is simi- 

 lar to one first made by me for Dr. Apjohn, and under his 

 directions ; it is a very simple instrument, and extremely con- 

 venient for daily or rapid observations ; there is no floating 

 gauge used, nor is it necessary to make any observation at the 

 cistern ; the fluctuations in the height here are nearly all 

 avoided, by very much increasing the area of the cistern over
