174 SYSTEMATIC ARRANGEMENT OP PLANTS. 



of particular sizes, colours, and polish, into their appro- 

 priate papers. Philosophy it cannot be, in any genuine 

 acceptation of the term, and it is an insult upon com- 

 mon sense to make the assertion. In the system of 

 Jussieu indeed, there is more exercise given to the 

 mind from there being more circumstances to observe 

 and consider, than in the Linnaean system; and, in 

 many instances, the plants grouped together are more 

 congruous, or in keeping, as a painter would say, and 

 therefore it is more in accordance with divisional logic ; 

 but to more praise than this the so-called Natural 

 System does not appear to me to be entitled. 



First Lesson on Jussieu s System. 

 The beginner, when it is required to class a plant in 

 this system, must first procure the seed and examine 

 the seed-lobes, and this must furnish an answer to one 

 of the following questions : 



1. Has it any seed-lobes?) No '- Tllen * belon S s to D ion I. 



J Yes. Then see question 2. 



"\ One Then it belongs to II. 



2. How many seed-lobes has it ? L Two or more Then it 



J belongs to ... III. 



Or, 



If the seed cannot be found, the stem or the leaves 

 must furnish answers to the following questions : 



l . Are there any sap ^ No Then it belongs to Division I. 



and pulp vessels ? J Yes Then see question 2.
