APPENDIX II 141 



For various morphological questions and especially, for 

 definitions, both teacher and students should consult Gray's 

 well-known text-books with the glossaries. The writer 

 fully believes that the students should be taught to define 

 and to interpret definitions, and that it is well for them to 

 consult several glossaries and dictionaries ; comparing and 

 selecting the good definitions. 



Beyond these books are many others, but the writer 

 believes that this list will be sufficient for a beginning and 

 that by these books others will be suggested. 



Reviews. The teacher should try to review the work of 

 each chapter with the students at the close of the work upon 

 it. Quizzing upon the special points brought out and any 

 questions bearing upon them, help in this. Each chapter 

 should be a sort of unit in the minds of the students, and 

 the inter-relationships of the various units making up the 

 book should be brought out and emphasized. 



Time. Each laboratory session should be at least an 

 hour and a half long. Two hours is about the best labora- 

 tory period for beginners. Three times a week is about the 

 proper frequency for laboratory exercises. If a course is to 

 run through the year, it should begin, of course, at the begin- 

 ning of the year, i.e. in most cases in the late summer or 

 early autumn. By properly preparing certain materials 

 ahead, the course as laid out in this volume may be given 

 at almost any time of the year and a considerable portion 

 of the material be procured in a living condition. 



Laboratories. If the laboratory can have tall, wide win- 

 dows facing mostly to the north, it will possess more advan- 

 tages than any other. But almost any airy and well-lighted 

 room will serve very well for students beginning in this 

 simple way.
