Journal of Meteorological Observations. 347 



The results of these two instruments are highly interesting, 

 particularly those of the radiating thermometer, from which it 

 appears, that only in one month (July) was the minimum 

 temperature observed to be above the freezing point ; this 

 is exemplified by the lower line in the middle one of the 

 three opposite diagrams, which are similar to those appended 

 to the Journal of 1826, and which are fully explained at page 

 128 of this volume of the Transactions of the Society. They 

 exhibit the mean pressure, temperature, and dew point, at 

 three periods of the day during each month in the year, as 

 well as the extremes of temperature in the sun, and of that 

 produced by radiation ; together with the quantity of rain 

 which fell in each month, amounting to 22.18 inches in the 

 course of the year. 



The monthly mean results, as well as the average mean for 

 the year, arranged in a tabular form, similar to one which 

 Dr. Burney, of Gosport, had the kindness to communicate 

 to me, will be found at the end of the Journal.
