ANALYTICAL TABLES. 



The object of scientific tables is usually twofold. First, philosophical ; to ex- 

 hibit in one condensed view the affinities and differences of the several subjects to 

 which they relate, by bringing them into immediate comparison and contrast. 

 Second, practical; to aid the student in his researches by affording him an 

 abridged method of analysis. The analytica. tables which accompany this flora 

 may subserve both these purposes, but they are designed chiefly for the latter; viz. 



* In this flora, wherever no authority is added to the generic or specific name, Linn, is to he 

 understood.
