TO THE STUDENT 



The study of animals is a fascinating subject, but, remember, 

 you must study the animals. A machine is interesting to you 

 if you can experiment with it, just to see what you can do with 

 it or make it do for you. Just so with animals, you must 

 study the animal "machine," living and dead, to understand 

 something of what it can do and the why of its existence. 

 Everything about a machine is there for some purpose. So 

 in an animal, everything you see has or has had a use. You 

 may not be able to determine what it is, but you can try to 

 find out in the same spirit you try to find out the use of the 

 parts of a machine. In your study of the animal machine 

 you must use your mind and some .tools to enable you to find 

 out the wonderful make-up of it, for it is far more wonderful 

 than any other machine you ever worked with. 



The dissection may not be pleasant to some of you, but all 

 things worth while cost something. Forget the odors and 

 ''ask the animal" what you want to know. Look and think 

 of what you are trying to find and of its use to the animal. 

 Look even further, for the principles which underlie its struc- 

 ture and use. Finally, you will see that you have much in 

 common with the animals about you. You are influenced by 

 your environment and heredity much as they are. You will 

 see also that you are dependent upon them for many things 

 necessary to your daily existence and comfort. Get your eyes 

 open while you are alive. See and enjoy the beautiful, won- 

 derful world in which you live.
