4 PRACTICAL PHYSIOLOGY 



2. The Method used. 3. The Results obtained. 4. The Con- 

 clusions drawn. 



Every student should be provided with a large note-book, pencil, 

 strong sharp-pointed scissors, strong dissecting forceps, and a 

 camel's-hair brush. 



After completing each set of experiments he should read in a Text 

 Book the results obtained and the conclusions arrived at by others, 

 and by further reading and lectures he should extend the knowledge 

 gained from his own work. 



Students who have not made themselves familiar with the 

 electrical apparatus which is used in physiology will find a brief 

 description in the Appendix (p. 77). 



The Course consists of seventeen lessons, each occupying about 

 two hours. In some of them it will be found convenient to divide 

 the class into sections, each spending half an hour or an hour on 

 one part of the work, and then exchanging with the other section. 



To help the teacher in preparing for the Class, a list of what 

 should be got ready is appended to each lesson. 



It may be found of advantage to alter the order of the lessons. 

 If Respiration and Circulation are taken before Nerve-Muscle, a 

 more gradual passage from easier to more difficult experiments 

 is secured. If the Class has not already done physiological work 

 in its Biological Course, it may be advantageous to start with 

 Lesson XVII ; 111. If such work has been already done this may 

 be omitted.
