MEMOIRS OF DECEASED FELLOWS 263 



water, which is within the drainage area of Hemlock lake, an 

 analysis of the water of this lake was made by Professor Latti- 

 more. The results of this examination were published in the pro- 

 ceedings of the Academy in connection with a paper given by 

 George W. Rafter and Dr. M. L. Mallory on the subject of this 

 epidemic. 



On May 14, 1894, Dr. Lattimore read an able paper before the 

 Academy on "The Recent Epidemic of Typhoid Fever in Buffalo," 

 drawing particular attention to the imperative necessity of a close 

 attention to the water supply of a city, and congratulating Roch- 

 ester on the fact that its supply was drawn from Hemlock lake 

 instead of Lake Ontario. This was printed in volume 2, of the 

 Proceedings, pages 270-278. 



Dr. Lattimore was ever progressive and kept fully posted on all 

 matters of scientific interest. At a meeting of the Academy held 

 October 28, 1895, he described the newly discovered element Argon 

 and discussed its nature, its utility, and the manner in which it 

 was discovered. In October, 1898, he described in a very interest- 

 ing manner the geological formations and natural beauties of 

 Mount Desert Island, on the coast of Maine, where he had spent 

 his vacation. 



Dr. Lattimore was always deeply interested in all that pertained 

 to the welfare of Rochester, and was specially anxious that the 

 city should do everything possible to preserve its beautiful natural 

 features. In April, 1895, at the conclusion of a lecture by Pro- 

 fessor H. L. Fairchild on the Geology of the Pinnacle Hills he 

 presented the resolutions, unanimously adopted by the Academy, 

 and printed in the Proceedings, volume 3, pages 178-179. 



Dr. Lattimore's latest appearance before the Academy was last 

 October, when, at a meeting devoted to a Retrospect of Science in 

 Rochester, he spoke informally, in his usual pleasant manner, of 

 the work of Professor Lewis Swift in astronomy, and supplemented 

 Professor Fairchild's remarks on the work of Professor Henry 

 A. Ward by a number of interesting personal reminiscences of that 

 distinguished scientist and traveler.
