yet robbed of the power of development. Therefore, the 

 importance of a connected study of the types of each kingdom 

 would seem to be self-evident. 



But little consideration is necessary to show whether plants 

 or animals should be first studied. Their generally less com- 

 plicated structure and their much less complicated physiology, 

 so far as general principles are concerned, the greater clearness 

 with which they illustrate such fundamental facts as those of 

 cellular structure, and the fact that they are the primary elab- 

 orators of organic substances all mark the plants as best 

 adapted for study by beginners and for the elucidation of the 

 elementary phenomena of living beings. 



A half year of such work as has been here outlined, followed 

 by a similar study of animal forms, ought to lay a substantial 

 and most useful foundation for future studies in medicine or 

 in zoology or botany.
