 perceptible may wet weather be anticipated ?

 rain falls, by sudden dashes of water over the surface, they prevent 

 the drops of rain from penetrating to their bodies through the open 

 and dry feathers. 



HOG. Why do houses and cattle stretch out their necks 

 and snuff the air on the approach of rain? 



Because they smell the fragrant perfume which is diffused in th* 

 air by its increasing moistness.
