4. Obtcrvaliont on the Temperature of the Almotpkere. 



Till within the last ten years, very few register* 

 of the thermometer were kept in Scotland. From 

 roost of those which were kept, the results were . 

 deduced on very erroneous principles ; and in almoet 

 all of them the observations were made at noun, 

 which did not give the mean temperature of the day. 

 Such of our readers as wish to consult these tables, are 

 referred to the General Report of Scotland, Vol. IV. p. 

 132. where they will find the leading results. 



The earliest observations on temperature which seem Ilavkhul. 

 to have been made with accuracy, are those taken at 

 Hawkhill near Edinburgh. They were made at 8 h 

 A.M. and 2 h P.M., but as these hours do not give the 

 mean temperature of the day, but a result almost ex- 

 actly 1 degree higher, we have added the corrected 

 mean temperature..*

The next series of good observations made in Scot- Edinburgh, 

 land were those of Professor Playfair, from 1791 to 

 1799 inclusive, 265 feet above the sea; but as these 

 observations were made at 8 h A. M. about 3 h the time 

 of maximum heat, and about 10 fl P.M. the time of 

 maximum cold, a correction of 35 requires to be 

 applied to them. Mr. Play fair supposed that the mean 

 temperature occurred about 8 h A. M. and that the great* 

 estcold was about 10 P.M.; and hence he concluded, that 

 by obtaining the me&n of the maximum and minimum, 

 and the general mean at 8, and by taking the mean of 

 all three, he would get the mean temperature of the 

 day. As the mean temperature, however, occurs at 

 9j h A.M. and the minimum about 5 h A.M. it is obvious 

 that the mean obtained by Professor Playfair must ex- 

 ceed the true mean.

This and other corrections applied above, are deduced from the houily meteorological regitter kept at Leith, for the year 18?4 and 

 1825. See the Transactions of the Koyal Society of Edinburgh, Vol. X, fart II. now in the presc.
