With regard to the last column, it may be remarked that it 

 contains the mean result of observations made daily at 8 a. m. 

 and 8 p.m. from August 16. 1827 to August 15. 1828, both in- 

 clusive. It exhibits clearly the extraordinary mildness of the 

 season, which appears to have raised the temperature of the air 

 more than two degrees above that of the earth, as shewn by the 

 springs. The reduction of the annual temperature, as observed 

 at 8 A. M. and 8 p. m. is taken from the Report of the hourly 

 observations at Leith. The difference of 0°.24 between the two 

 springs is attributable to their difference of level, to which it 

 nearly corresponds. The atmospheric temperature for August 

 is a mean of the first half of that month in 1828, and the se- 

 cond in 1837. J. D. F.
