SUGGESTIONS TO STUDENTS 



Spirit of Study. The students should attempt to get at 

 the reasons which lead to the selection of a natural science 

 as a portion of their course of study. It is not only a matter 

 of acquiring a certain amount of information which will be a 

 source both of profit and of pleasure in the future, but also 

 to train certain faculties to act in an orderly and effective 

 manner. To learn to observe carefully is a matter of the 

 utmost importance in all the ordinary things of life. Many 

 of our mistakes are the direct result of hasty observation and 

 inference. Without accurate observation, we can have no 

 certainty as to the accuracy of our inferences and whenever 

 we think -it over we realize that even the simple matter of 

 recognizing an object, its shape, etc., is really a matter of 

 inference. But after we make out what the shape and 

 general structure of an object is, we have still to infer from 

 these details its use, relations to other objects, etc. 



Consequently, in laboratory work of any kind, the name of 

 the object or of its parts are purely matters of convenience, 

 to assist the memory and to enable us to talk to others con- 

 cerning these things, but the principal matter in hand is to 

 notice every detail and variation in form both of the object 

 being studied and of its parts; then, from this as a basis, to 

 reason out why the object and its parts are constructed as they 

 are ; and finally to make a permanent record, both of the
