LEO LESQUEREUX. 463 



ations with so many illustrious minds had not stored his mem- 

 ory with anecdote and reminiscence, Lesquereux responded : 

 " The science students' life is absorbed with grave and serious 

 truths ; they are naturally serious men. My associations have 

 been almost entirely of a scientific nature. My deafness cut 

 me off from everything that lay outside of science. I have 

 lived with Nature, the rocks, the trees, the flowers. They know 

 me, I know them. All outside are dead to me." 



Dr. Lesquereux's death occurred at his modest home in Colum- 

 bus, Ohio, on October 25, 1889. His wife had shortly gone be- 

 fore. He lived and died in the communion of the Lutheran 

 Church, and never felt the essentials of his religious belief dis- 

 turbed by the advances of science. A visitor described him at 

 the age of eighty as " a middle-sized man with dark eyes that 

 flashed with mirthfulness when tie spoke, and a step so brisk, 

 and hair and beard so free from time strokes, that the long- 

 cherished patriarchal vision of the botanist's appearance van- 

 ished." 



Four sons and one daughter lived to adult age. The sons 

 followed in their father's footsteps, not in the pursuit of sci- 

 ence, but by becoming watchmakers. 



The last work upon which Prof. Lesquereux was engaged 

 was an important treatise on The Flora of the Dakota Group, 

 which was published posthumously under the editorship of Mr. 

 F. H. Knowlton as Monograph 17 of the United States Geo- 

 logical Survey, in 1891.
