136 THE MICROSCOPE. 



" As for the general system of atmospherical 

 circulation/' it is added, " which I have been so

 all in a single sentence : i The wind goeth to- 

 ward the south, and turneth about unto the 

 north ; it whirleth about continually ; and the

 (See the connection, Eccles. i. 7.) At the point 

 where we have arrived, Maury admits, that while 

 this theory of the winds seems " highly probable" 

 from reasoning, proof is still wanting to establish 

 it as a fact, that the north-east and south-east 

 trades, after meeting and rising up in the equa- 

 torial calms, do cross over and take the paths

" Were it possible/' he says, " to take a por- 

 tion of air, representing, as it travels along with 

 the south-east trades, the general course of at- 

 mospherical circulation, and to put a tally on 

 it, by which we could follow it in its circuits, 

 and always recognise it, then we might hope 

 actually to prove, by evidence the most positive,
