course in mineralog}* and geology. Frorii 1875 to iSSi he 

 filled the chair of theoretical and applied chemistry in the Ar- 

 kansas Industrial University, and from 1881 to 1885 the chair 

 of biology, mineralogy and geology in the same institution. 

 He was in charge of Dr. A. E. Foote's natural history and 

 mineral establishment in Philadelphia in 1885 and 1886. He 

 went to Maine in the latter year to fill the chair of natural his- 

 tory at the University of Maine at Orono, and he held that po- 

 sition until his death. In addition, he was botanist and ento- 

 mologist to the Maine State Experiment Station connected with 

 the University. In 1890 the Arkansas Industrial University 

 conferred the degree of Ph. D. upon him. 



"At the University of Maine he was recognized as a hard 

 and faithful worker along the lines of science, and as an in- 

 structor he was well liked and had the esteem of all the stu- 

 dents coming under his department. As a resident of Orono he 

 \vas looked up to as one of the leading men of the town, and 

 many were his friends among the townspeople." 



His untimely decease was the result of ovenvork, leading to 

 nervous debility and melancholia. He is survived by a widow 

 and five children, to whom we tender our deep sympathy. 



His work on the Odonata began in 1890, since which time 

 he carefully explored various parts of Maine in the study of 

 its Odonate fauna. He made many interesting discoveries 

 of species hitherto rare or unknown in that region, such as 

 Ciomphns nirriits and Scudderi, Neurocordulia vamaskanensis^ 

 Somatochlora septentrionalis and the new Ophiogomphus anouut- 

 lus. The last two months of his life, when he could work, were 

 devoted to preparing the results of his collecting trips of 1 899 

 for publication. These manuscripts he committed to our charge 

 three days before his death. 



The Thysanura and Collembola of Maine had also received 

 much attention from him, and among them he had discovered 

 a number of new species. 



His writings on Economic Entomology were published chiefly 

 in the Annual Reports of the Maine State College Experiment 

 Station. The most extensive and important of these deals 

 with the Apple Maggot ( Trypeta pomonella) and appeared in 

 1889. We are informed that he also published on fossil and 

 recent plants, on forestry and allied subjects. P. P. CALVERT.
