another subject of investigation connected 
^vith the present flora of the earth, namely 
botanical geography. The minor differences 
which afford remark as we pass from the 
sylvan scenery of one part of England to 
that of another, or as we admire the wild 
flowers common in one place and scarce in 
another, are the types of variations more 
extensive and complete throughout the 
world. The arrangem ent of plants, which 
actually obtains over the globe, cannot be 
entirely accounted for by considerations of 
climate, temperature, and soil. 
The well-known prevalence of particular 
kinds of plants in certain districts, has led 
to the attempt to divide the whole earth 
into floral provinces, each distinguished by 
characteristic vegetation. This novel kind 
of geography is best delineated in an elabo¬ 
rate work by a Danish professor, Mons. 
Schow,* who reckons twenty-two great 
divisions of the globe, each sub-divided into 
lesser provinces. His first region is that of
