WEATHER INDICATIONS BY BAROMETERS. 149 



merely threatening a locality with their invasion, they are 

 turned aside, and go off elsewhere. In this case, if 

 we watch the newspapers, we shall probably hear of 

 its effects at the points which had to undergo the brunt 

 of the attack, that we have been fortunate enough to 

 escape. At other times it may be that we may en- 

 counter a short but sharp stormy interval: this is the 

 same thing varied only by the fact that, instead of 

 escaping in toto, we have in this case come in for 

 "the tail of the storm," and so have experienced the 

 partial effects of the inrush of air from the edge towards 

 the centre of the disturbance. 



Having now briefly sketched some of the most pro- 

 minent features connected with the barometer in its 

 relation to atmospheric disturbances, we shall bring 

 this chapter to a close, and with it the first division 

 of our work; and next proceed to describe, in their 

 order of succession, our six great Climatic Zones.
