102 FAMILIAR LESSORS IN BOTANY. 



You have seen how the well-being of both the vegetable 

 and animal kingdom depends on the seeming discord of 

 tbeir forces; that they are 



'* Formed for one another, though dissimilar,'* 



and work together for the good of man with a beneficence 

 and wisdom that fills the Christian heart with profound 

 awe and adoration. 



CHAPTEK XIV. 

 Classification, 



Section I. — Artificial System. 



To classify plants is to arrange into groups and. 

 families those that bear the closest resemblance to each 

 other. Botanists have taken different circumstances as 

 the grounds for this resemblance, and consequently we 

 have several systems of classification. You should make 

 yourselves familiar with both the Linnaeau or artificial, and 

 the natural system. The first named is founded upon the 

 number, length, and situation of the stamens and pistils. 

 This first division is into phenogamous, with stamens and 

 pistils visible ; and cryptogamous, stamens and pistils in- 

 visible. The phenogamous plants include the first twenty 

 classes. 



As a knowledge of Latin and Greek numerals is neces- 

 sary in order to understand the names of the classes and 

 orders, you will commit the following to memory:
