bound in contrast, whilst another division 
is dazzling with groiipes of flowers of similar

the works of creation possesses continually 
before him these two sources of interest— 
variety and order. 
The reduction of the subjects of our con¬ 
sideration into certain assemblages possess¬ 
ing some appearances in common, would be 
a natural employment of the observer, and 
a considerable portion of the study of botany 
is occupied with its classification. 
Botanists divide the whole vegetable king¬ 
dom into six classes: 
I. Agamce^ or flowerless plants. 
II. Crgptogamia Cellulares, plants com¬ 
posed of simple cellular tissue, with flowers 
concealed.. 
III. Crgptogamia Vasculares, in which 
distinct vessels are added to cellular tissue, 
and the flowers also concealed. 
IV. Phanerogamia Ggmnospermia, flow¬ 
ering plants with naked seeds. 
V. Phanerogamia Monocotyledones, flow¬ 
ering plants with one-lobed seeds.
