Leo Lesquereux.— Born in Fleurier, Switzerland, Nov. 18, 

 1806, died in Columbus, Ohio, Oct. 25, 1889. On entering the Academy 

 of Neuchatel he met Arnold Guyot and together they became de- 

 voted to natural science. In 1822 he went to Eisenach preparatory 

 to entering the University of Berlin, supporting himself by teaching 

 French. He was principal of a college at Chaux de Fonds but had 

 to give this up on account of deafness. From this time he did 

 engraving, made watch springs, and studied Mosses and fossil 

 plants. 



In 18-1:8 Lesquereux came to America settling at Cambridge, 

 where he assisted Louis Agassiz; but he soon removed to Columbus, 

 Ohio, where he lived until his death. He was a worthy associate of 

 William S. Sullivant to whom in fact he was indebted by the most 

 commendable generosity. He was a paleo-botanist and a student of 

 Mosses. Many i^lants are named for him including a large number 

 of fossil forms.
