Abstract of Thermometrical Observations made at the Apart- 

 ments of the Royal Society of London. 

 [Referred to p. 287. & 356.] 



Explanation. — Column 2d contains the Mean Monthly Tem- 

 perature, as derived from 20 years' observations, made between 

 the years 1795 and 1814 inclusive. Column 3d is the Calcu- 

 lated Temperature by the formula in Table G, founded on the 

 ratio of increase and decrease of temperature, as obtained from 

 50 years'" observations at Stockholm. In the use of this for- 

 mula, the temperatures of January and July are all the data 

 requisite. Column 4th is the difference between the calculated 

 and observed temperatures, which, it will be observed, in no in- 

 stance amounts to 2 degrees. Column 5th contains the Mean 

 Monthly Temperature from 37 years' observations, viz. from 1772 

 to 1780 inclusive, and from 1787 to 1814 inclusive. Columns 

 6th and 7th are of the same nature as the 3d and 4th. The 

 greatest difference of the calculated and observed temperatures, 

 month of February (in which there is possibly some error) ex- 

 cepted, is 1''.7, and the average difference is 0°.7.
