diagrams readily conveys to the eye the points of agreement 
and difference on which the classification rests. The geologi-

Dicotyledonous plants occupy three cases on the left side of 
the gallery, and are followed by the Monocotyledonous Orders, 
which fill the last case on the same side, the two half cases at

door. The Gymnosperms are placed in the next case. Then 
follow the Cryptogams, a case being devoted to the higher 
vascular Orders, and another to the lower division of cellular
