TABLE F. 



Containing an Abstract of 50 years Observations on the Tem- 

 perature of Stockholm, collated for the purpose of ascer- 

 taining the ratio of Increase and Decrease of Temperature 

 with tbe Advance of the Year. 



[Latitude of Stockholm 59° 20' 31"; Longitude 18° 3' 51" E.] 



[This Table is referred to in p, 287. 290. 356. & 359.] 



This Abstract is derived from an interesting Table in the 

 " Annals of Philosophy," vol. i. p. 113. The last column is 

 the result of 54.750 observations. But as the ratio of increase 

 of temperature from January to July, and the ratio of decrease 

 from July to January, are not exactly regular, the 2d, 3d and 

 4th columns are taken from the application of the nearest regu- 

 lar ratio to the actual observations, and are considered as being 

 the pi-obable result of the thermometric observations, had they 

 been conducted through a series of several centuries. The 

 difl'erence between the temperature of January and that of July 

 being considered as 1.000, column the 5th shows the propor- 

 tionate difference between the temperature of January and that 

 of any other month in the year. By the use of these decimals, 

 in connection with the formulae in the next table, the mean tem- 

 perature of any month, in any country situated to the northward 

 of the 50th degree of latitude, may be calculated, provided the 

 temperature of the months of January and July, or the mean 

 temperature of the year and that of July be known.
