138 THE MECHANICS OF THE EARTH'S ATMOSPHERE. 



For (p=—cc, we tberefore have y=+co, and the stream flows with a 

 velocity of 1 in the direction of the negative axis of y; for <^=-|-gc, we 

 have x= =p oo, and y=— oo, and the stream flows with a velocity of 1 in a 

 direction that makes an angle whose cosine is ^pfc with the direction of 

 the positive axis of x. 



In Fig. 8 the boundaries of the moving fluid are represented for this 

 case.
