botany. He, however, between 1868 and 1890, delivered 
twenty of the public “ Lectures to Mechanics” given in annual 
courses at the Sheffield Scientific School. They were all upon 
subjects related to botany, such as Trees of New England; 
Our Common Weeds; Seaweeds; Mosses; Hybridism in 
Plants; Oaks; Water Lillies, ete. These lectures were writ- 
ten in his genial style, and were very popular. . 
The most of his botanical work was done in his study or in 
the fields and woods about New Haven. In connection with 
the work of The Geological Survey of the 40th Parallel, he 
spent a part of the summer of 1869 in Utah, and was intensely 
interested in the study and aspects of the vegetation of that 
part of the Great Basin. He spent much of the year 1866 in 
Europe, and then took occasion to consult and examine speci- 
mens in several of the herbaria there. 
Professor Eaton was fond of literature, and retained a love 
for the ancient classics. He became deeply interested in his- 
torical and genealogical studies, and was an officer in several 
societies devoted to these subjects, and was also the secretary 
of his college class. He carried on a wide correspondence, 
and published several papers relating to these subjects: Of 
the sixty-four titles given under his name in the “Yale 
Bibliographies,” fifty-six were botanical. Reviews of botanical 
books, published in the Nation, some of which might rank as 
scientific “‘ papers,” are not included. | 
Regarding his personal qualities I cannot do better than 
quote the language of another. ‘ An ardent enthusiast in his 
chosen science, ever ready to aid those seeking its lights, 
Professor Eaton owned as a natal gift a most graceful and 
winsome personality. He was singularly but unobtrusively 
helpful in every social relation, generous and tender in his 
charities, always eager with some self-sacrificing act of neigh- 
borly kindness. He took keen interest in the polities of city, 
state and nation. He loved intensely the out-door life of wood- 
land and field, and was fond of out-door sports.” 
He appeared in his usual good health until last year. While 
botanizing for mosses and particularly sphagna in the White 
Mountainsin the summer vacation, a malady before unsuspected 
began to acutely manifest itself. Although the disease was 
very painful, he did some botanical work in the autumn,but he 
attempted no college work after the Christmas recess. He 
endured his sufferings with Christian resignation, and passed 
away with the college year, two days after Commencement. 
He married, February 13th, 1866, Caroline, daughter of 
Treadwell Ketchum, of New Haven. She, a son and a daugh- 
ter survive him.
