From this, it appears that in the higher latitudes, the aver- 
age difference for the same degree of mean temperature, is 
14° 30’, and in the lower ones 7° 30’, the mean of which is 
11°. Thus the mean temperature at Stockholm, i in latitude 
59° 20’, is about the same as at Fort Sullivan, in latitude 
44° 44’; while that at Rouen, i in latitude 49° 26’, is about 
the same as at Fort Wolcott, in latitude 41° 20’; iad at St. 
| in latitude 29° 50’ it is but 0.77 lower than at 
Grand Cairo, in latitude 30°,
