16 A FEW FACTS ABOUT ZOOLOGY. 



thought under a thousand different aspects. Some new cut 

 of the plates, some slight change in their relative position, 

 is constantly varying their outlines, from a close cup to an

 cular, or square, or pentagonal form in others. An angle 

 that is simple in one, projects by a fold of the surface, and 

 becomes a fluted column in another; a plate that in one is 

 smooth, in another will wear a symmetrical figure drawn 

 upon it in beaded lines." The ornamentation changes, but 

 the pattern, throughout its changes, remains the same. It 

 would require an endless number of illustrations to give 

 even a faint idea of the variety of these fossils. 



Why must we always speak of these lower animals by long 

 technical names ? Why do we get our best ideas of them 

 from drawings rather than from real life ? " When the 

 forms of animals shall become as familiar to children as 

 their ABC, and the intelligent study of natural history 

 from the objects themselves, and not from text-books, is intro- 

 duced into all our schools, we shall have popular names for 

 things that can now only be approached with a certain pro-
