THE SOURCE OF THE NILE. 67% 
trade-winds are confined ; fet off again 16° from the 32°, 
that is, half the diftance between the Cape of Good Hope 
and the Line, and 16° between the Line and the Mediter- 
ranean, and you have the limits of the tropical rains, 16° on 
each fide of the equator: again, take half of 16°, which is 
8°, and add it to the limit of the tropical rains, that is to 16°, 
and you have 24°, which is the fituation of the tropics.— 
There is fomething very remarkable in this difpotition.
