PALEOBOTANY. 
A New Book on Fossil Plants.' — Dr. Scott's important contri- 
butions to our knowledge of fossil plants are too well known to 
students of palzobotany to need any introduction. The present 
Work is a very satisfactory summary of much of his former work, and 
the substance of it was first presented in the form of a series of 
lectures delivered at University College, London, in 1896. The 
lectures, however, have been entirely recast and brought up to date.
