stated meeting. 



The President, Professor H. L. Fairchild, in the chair. 



Seventy persons present. 



The fourth lecture of the Popular Lecture Course was delivered 

 by Professor Lester F. Ward, of the U. S. Geological Survey, 

 Washington, D. C, entitled : 



THE VEGETATION OF THE ANCIENT WORLD. 



The lecturer began with some remarks on the age of the different 

 fossil forests, illustrated by the lantern views, using some of the 

 estimates that have been lately made by eminent geologists as to the 

 number of years that have elapsed since the beds containing the 

 fossils were deposited. The lecture consisted of an explanation of 

 some thirty views thrown on a screen, representing in chronological 

 order the several floras that paleontology has revealed, beginning 

 with the Devonian, as illustrated by Dawson, showing the great 

 Carboniferous flora, chiefly from views from Heer and Gran d'Eury, 

 then passing up through the Mesozoic and Tertiary to the Pleisto- 

 cene. The Mesozoic and Cenozoic ages were largely illustrated from 

 American specimens that have been figured in the works of Fontaine, 

 Lesquereux, Newberry, and the lecturer.
