Meteorological Obfervations. 557 
Mean annual height and range of the Ther- 
mometer at Dover for the preceding years. 
“Years. | Mean. | Higheft. | Loweft. | Range. 
1789 40 57 27 30 
1790 45 86 26 60 
1791 44- 23) 26 50. 
1792 44 78 16 62 
31793 46 | 77 25 52 
_ From this it would appear, that the mean 
heat at Dover is 53°: the greateft degree of 
heat noticed in the abistvations for the pre- 
ceding rect 86°; the leaft 16: the greateft 
range 70°; and the mean annual range st 
nearly. 
The mean here is however lower than an 
truth, owing to the -obfervations of the firft 
and laft years not ‘being complete. 
If we take the three complete years, viz. 
1790, 1791, and 1792, the means will ftand 
thus. 
Annual mean 44°. 
Annual range 57. 
I cannot, however, but fufpe@ that the mean 
annual heat at Dover, will be found greater 
than it is given by calculation from thefe ob- 
fervations. 
The obfervations were taken three times 
a day, at eight o’clock A. M. at four and ten 
P.M.
