PRELIMINARY. 



THROUGHOUT this Course the student must keep careful 

 records of every experiment he performs, and these must be 

 made as the experiment proceeds and not some time after its 

 completion. When apparatus is used, he must make diagrams 

 of its arrangement, and, when tracings are taken, these must 

 be fixed and preserved. 



Before beginning an experiment he must first clearly 

 understand its object, and no student will be allowed to con- 

 tinue an experiment who has not entered in his note-book the 

 question to be investigated. 



He must also, before starting, understand the method 

 adopted and how it will throw light upon the question. 



While carrying out the experiment he must not confine his 

 attention only to the main result, but must observe everything 

 which happens, and record for further investigation anything 

 he does not understand. The experiment must be carried 

 through without any preconceived idea of what the results 

 should be, and an attempt must be made to draw conclusions 

 from the results obtained, and to give an answer to the question 

 which is under investigation. 



In every experiment the student must record : 



1. The Object, 



2. The Method used. 



3. The Results obtained. 



4. The Conclusions drawn. 



Every student must be provided with a large note-book, 

 pencil, strong sharp-pointed scissors, strong dissecting forceps, 

 and a camel's-hair brush.
