CLOUDS. 131 



Q. How can ELECTRICITY affect the SHAPE of 

 CLOUDS ? 



A. If one cloud be full of electricity, 

 and another not, they will be 

 attracted to each other, and either 

 coalesce, diminish in size, or vanish 

 altogether. 



Q. WHICH CLOUD s assume the most FANTASTIC 

 shapes ? 



A. Those that are the most highly 

 electrified. 



Q. What effect have WINDS on the SHAPE of 

 CLOUDS ? 



A. They sometimes absorb them 

 entirely : sometimes increase their volume 

 and density ; and sometimes change the 

 position of their parts. 



Q. Haw can WINDS ABSORB CLOUDS altogether ? 



A. A warm dry wind will convert 

 the substance of the clouds into invisible 

 vapour, and carry it in its own current. 



Q. How can WINDS INCREASE the bulk and 

 density of CLOUDS ? 



A. A cold currentof wind will condense 

 the invisible vapour of the air, and add it 

 to the clouds as it passes by.
