VEGETABLE KINGDOM. 



In the first edition of this work, no attempt was made to arrange the fossils of the 

 vegetable kingdom, represented in the palaeozoic rocks, into classes, orders, or families, 

 for reasons then expressed ; since that thne, however, the work of Leo Lesquereux on 

 the coal flora of Pennsylvania has rendered possible a classification which will be of 

 some utility, though only approximately correct.
