SYSTEMATIC ARRANGEMENT 
of the plans now zealously advocated by a few natur- 
alists in this country promise to answer this end, forms 
no part of our present purpose to enquire. In com- 
mon with all others hitherto proposed, they recognise 
certain primary divisions of the class, many of them 
corresponding, or nearly so, to those established by 
Linn ee us ; these divisions, therefore, as forming the 
most generally approved basis of arrangement, and of 
fundamental importance in every point of view, we 
design to explain at some length, and illustrate by a 
variety of examples. They are termed Orders , and 
are the first subdivision of the class. The following 
is a tabular view of them, with concise distinctive 
characters.
