AISTNIVERSARY ADDRESS OP THE PRESIDENT. 53 



Piedmont and Liguria formed the principal subjects of his scientific 

 writings. Por thirty years he was a professor of the " Liceo 

 Gioberti " at Turin and at the same time keeper of the palseonto- 

 logical collection in the Koyal Geological Museum of that city. The 

 great richness of this collection, especially in Tertiary Mollusca, is 

 chiefly due to Bellardi. Besides his papers on palaeontology, the 

 majority of which were published in the ' Memorie della Eeale 

 Accademia delle Scienze di Torino,' Bellardi wrote on entomological 

 subjects, and especially on Diptera. He was made a Foreign Corre- 

 spondent of our Society in 1880, and died 17th September, 1889. 



By the death of Leo Lesquereux, which took place at Columbus, 

 Ohio, on the 20th of October last, one of the principal palseo- 

 botanists of the world is lost to us. He was born at Fleurier, in 

 the canton of Neuchatel, Switzerland, in 1806, and was of French 

 Huguenot descent. He was educated for the church at the Neu- 

 chatel Academy, but, having become deaf at the age of 26, he worked 

 for twelve years as an engraver of watch-cases and a manufacturer 

 of watch-springs. His taste for natural history, however, gradually 

 made him known, and in consequence of his repute, gained by 

 researches on mosses and peat, he was employed by the government 

 of Prussia in 1845 to examine the peat-bogs of Europe. A trans- 

 lation of one of Lesquereux's later papers on the formation of peat 

 appeared in the Society's Journal for 1818. 



Lesquereux went to the United States in 1848, and was at first 

 engaged there, as he had been in Europe, in the study of mosses; 

 bat from 1852 he became botanical palieontologist to several geolo- 

 gical surveys, and he published in succession a series of reports and 

 monographs relating to fossil plants from Pennsylvania, Arkansas, 

 niinois, and Mississippi. His best-known works, and perhaps his 

 most important, were a series of monographs issued between 1878 

 and 1883 on the Cretaceous and Tertiary floras collected by the 

 Geological Survey of the Territories under Dr, Hayden, and a work 

 in three volumes, one of them an atlas of plates, on the Coal-flora ot 

 Pennsj'lvania and the United States, published between 1880 and 

 1884 by the Second Geological Survey of Pennsjlvania. He was a 

 member of the United States National Academy and of many Euro- 

 pean scientific bodies, also an honorary professor of the Academy of 

 Neuchatel. He was made a Corresponding Member of our Society 

 in 1880, and received the award of the Barlow-Jameson Fund in 

 1884.
