APPENDIX 

 A SYLLABUS OF LABORATORY WORK 



The laboratory exercises here outlined have been used 

 by the author in his instructional work. 



Each student performs the exercises, so far as possi- 

 ble, and the apparatus needed is provided. The student 

 should be required to write a description of the work 

 performed, stating results in every case, supplementing 

 his notes by drawings in special cases. 



It has not been found practicable to make the lecture 

 room and laboratory work fully correspond as to time, 

 but the effort has been made to do this as far as possible. 



A greenhouse is very desirable for this kind of in- 

 struction, and if the instruction is given in winter, a 

 " garden house," i.e., a glass house inclosing an unob- 

 structed area of garden soil is scarcely less important. 

 But in the absence of these conveniences, a few window 

 boxes will furnish a tolerable substitute. 



When the exercises are carried out during winter, con- 

 siderable foresight is essential to have the needed mate- 

 rials in condition for use at the proper time. 



To stimulate observation (1).^ — A few object lessons 

 are given to encourage observation and correct reason-
