ALPHEUS HYATT. 



him, for his relatives in Maryland sympathized with the South. 

 He gave efficient aid in raising and instructing a company in 

 Cambridge, and he was commissioned a lieutenant, although he 

 was soon promoted to the rank of captain in the 47th Massachu- 

 setts regiment. He enlisted a second time at the end of his first 

 term of service, and he was mustered out at the end of the war, 

 in 1865. It was not until nearly thirty years after that his rela- 

 tives became reconciled to their Union veteran ; but we who knew 

 him as a man of science will regard as some compensation the 

 military bearing that contributed to the impressive dignity of 

 his presence. 



He returned to Cambridge in 1865 to renew his researches 

 under the guidance of Agassiz, devoting himself to the study of 

 the fossil cephalopods. The same year he was made honorary 

 curator of the Museum of Comparative Zoology and put in 

 charge of the fossil cephalopods. He continued to hold this 

 position to the end of his life. During the thirty-nine years that 

 remained to him the study of these fossils held the foremost 

 place in his thoughts. His first important memoir, which was 

 published in 1866, gives some of the results of six years of 

 interest in them. Another memoir on the same subject followed 

 in the next year, and others in succeeding years, the last being 

 published in 1901, only a few months before his death. 



In 1867 he married Ardella Beeby, of New York; and she, 

 with three children, survives him. 



The same year he moved to Salem, Massachusetts, and, with 

 three friends who had been his fellow-students at Cambridge, 

 continued scientific researches at the Essex Institute, of which 

 he and his three friends were made curators, and at the Peabody 

 Academy, which they cooperated in organizing in 1869. They 

 also founded and were the first editors of and contributors to 

 the American Naturalist, the first successful and permanent 

 journal of general zoology, as it is still the leading one. The 

 three friends who were so closely associated with Hyatt in these 

 early undertakings remained his life-long friends and collabo- 

 rators. They are our colleagues, Prof. E. S. Morse and F. W. 

 Putnam, and our late colleague, A. S. Packard. 



While at Salem in 1869, Hyatt was elected a fellow of the 

 American Academy of Arts and Sciences, of which he was one 

 of the vice-presidents at the time of his death.
