Tue mean temperature of Cape-Town, inferred from a meteo- 
rological journal kept there for several years, is 6740 Fahr*. 
The extremes, according to the same journal, are 96°, and 45°, 
But, as the thermometer, of which the account was kept, re- 
mained suspended in a large apartment, without direct expo- 
sure to external air, it cannot have indicated precisely the ex- 
treme of cold, nor perhaps that of heat. Besides, it is not self- 
registering. The mean temperature of the coldest month, as 
shewn by it, was 57°; of the hottest, 79°; mean of three win- 
ter months, 58°; of three summer months, 77°; least heat 
during summer, 63°. 
The temperature of an inland station, Stellenbosch, deduced 
from observations of a single twelvemontht, is 661°; extremes, 
87° and 50°. The temperature of Zwartland, another inland 
station, appears to be 664°; extremes, 85° and 54°. The ex- 
posure of the thermometers is at neither place external; they 
are suspended in spacious airy halls. 
At Tulbagh, situated in a valley of the great chain of moun- 
tains, which divides the western from the eastern districts of the 
colony of South Africa, the mean temperature of the year is
