262 ROCHESTER ACADEMY OF SCIENCE 



desire for a society that should cover a larger field being increas- 

 ingly manifest, in two years an expansion of the organization was 

 made, and the Rochester Academy of Science was incorporated 

 May 14, 1881. The names of the incorporators were Myron Adams. 

 H. F. Atwood, C. E. Rider, H. C. Maine, Adelbert Cronise, S. A. 

 Lattimore, William Streeter and Cyrus F. Paine. The Microscop- 

 ical Society was merged in the Academy as the Section of Micros- 

 copy. 



From the first. Dr. Lattimore was an interested and leading 

 member of the Academy, always willing to give the benefit of his 

 wide scientific knowledge for the good of the organization. In 

 later years, on account of his services, he was made an Honorary 

 Member of the Society. 



Dr. Lattimore did not present many formal papers to the Acad- 

 emy, but he was a frequent speaker in an informal way at the 

 meetings. His special interest was, of course, in chemistry, but he 

 was one of the old-time school of scientists whose knowledge ex- 

 tended over a broad field, and he was able to discuss almost any 

 scientific subject with intelligence and true appreciation of its 

 merits. His remarks were always so interesting, his illustrations 

 so apt, his examinations so clear and his manner of presenting a 

 subject so simple and lucid that he was always a welcome speaker. 

 His dignified but pleasant manner, of the old-school courtliness, 

 made him an ideal presiding officer when called upon to fill that 

 position. 



Such was Dr. Lattimore's reputation as an expert chemist, that 

 he was frequently called upon by industrial corporations, municipal 

 authorities, and courts of law for analyses, investigations, and ex- 

 pert testimony. As a chemist in the State Agricultural Depart- 

 ment for many years he rendered important assistance, and twice 

 he served as a member of the national commission of chemists to 

 test the gold and silver coinage of the United States. 



In 1872 he was employed by the Rochester water commissioners 

 to test the water of all streams and lakes which were supposed to 

 be available for the city water supply, and it was on the basis of 

 his analyses and advice that the city purchased Hemlock lake, and 

 later, Canadice lake.
