DIYISIONS OP TEE INIMAL KINGDOM. 



For the following division and analysis of the whole 

 animal kingdom, the writer is indebted to one of our 

 great natural scientists, Dr. Worthington Hooker. 

 The hundreds of animals which are distributed over the 

 earth have been divided into families according to their 

 food, habits, mode of living and other noticeable char- 

 acteristics. These are called by various names under 

 the existing circumstances, such as divisions, sub-divis- 

 ions, classes, orders, families and geneva; also species. 

 Variety is used to designate different animals of the 

 same species. By a careful study of the analysis of the 

 kingdom persons are enabled to designate the kinds of 

 animals which a piece of bone or tooth belongs to when 

 shown to them. It also facilitates the study of them 

 greatly, and it was for this end that the above named 

 author and other naturalists prepared this chart. Each 

 of these divisions have their peculiar characteristics. 

 The Vertebrates are known by having a back-bone and 

 spinal column. The articulates are known by being 

 composed of rings or sections, such as insects. The 

 mollusks are known as soft shelled or soft bodied ani- 

 mals. There are two kinds, one with heads, the other 

 without; some are terrestrial and others are sea animals. 

 The radiates or fourth division are the lowest of the 

 kingdom, and some of them seem to be almost without 

 life, the Polyps for example. Many of these animals 

 bear a resemblance to plants.
