BOOKS ON BOTANY.

The Geological History of Plants. 



By Sir J. William Dawson, F.R.S. Illustrated. 

 i2mo. Cloth, $1.75. 



The object of this work is to give, in a connected form, a summary of the 

 development of the vegetable kingdom in geological time. To the geologist 

 and botanist the subject is one of importance with reference to their special 

 pursuits, and one on which it has not been easy to find any convenient manual 

 of information. It is hoped that its treatment in the present volume will also 

 be found sufficiently simple and popular to be attractive to the general reader.
