Tur author is a distinguished member of the energetic band of 
workers in paleobotany whose labours have in recent years con- 
tributed to throw so much light on many obscure points of the 
vanished flora of geologic times. Dr. Scott was associated with the 
closing portion of the long scientific career of the late Professor 
Williamson, and is well acquainted with the collection brought 
together by that veteran paleobotanist ; therefore it is not sur- 
prising that much of the information here presented has been drawn 
from specimens contained in that collection, now national property, 
in the Natural History Museum, Cromwell Road. 
The volume is founded on a course of lectures given four years 
ago at University College, Gower Street, under the same title, but 
entirely recast in accordance with newer information which has 
been rendered accessible since these lectures were delivered. It is 
confined to setting out the results of inquiries of chief importance 
from a botanical standpoint relating to the two subkingdoms of 
Pteridophytes and Gymnosperms, all considerations of the lower 
cryptogams and the phanerogams being put aside. 
The author explains the difference in the condition of plants pre- 
served by incrustation and petrification—the former being most 
familiar to those people who visit geological collections, while the 
second is largely confined to the cabinets of specialists as admitting
