 SHARKS 



There are a great many different kinds of Shark. One, for 

 instance, the Little Dog-fish, is only about eighteen inches long. 

 It is very common off our British shores; and sometimes, after a 

 very severe storm, we may find it lying dead upon the shore. 



The eggs of this shark are very curious objects, and are some-

 oblong in shape, and black in colour. At each of the four corners 

 there is a long, slender " tendril ", very much like those which we 

 see on the pea and many other climbing plants.
