718 MEMOIR OF GUYOT. 



of New York, under Mr. James T. Gardiner; and "in the position of 

 this station," he says, writing August 12, 1849, " we agree perfectly." 



He discovered, by his explorations in the Catskills, nineteen summits 

 that were higher than the highest previously known, three of rhem over 

 4,000 feet above tide-level. For the highest, called " Slide Mountain," 

 he found the elevation 4,205 feet, while that of " High Peak," which 

 had been thought the highest, proved to be only 3,664 feet. 



This work, closing so grandly Guyot's study of the Appalachian sys- 

 tem — begun by him when he was forty-two years of age, was finished 

 in 1881 when seventy-four. It was his " vacation" work. His memoir 

 on the Catskills was published in 1880 in volume xix (third series) of 

 the American Journal of Science, with two illustrating maps. The oro- 

 graphic structure of the range is described, its origin briefly and 

 judiciously considered, and the heights given for over two hundred 

 points. A larger map (14 by 20 inches) was issued the year before as 

 a pocket niap. And thus his orograpnic labors have already contrib- 

 uted greatly to the convenience of tourists as well as to geographical 

 science. 



Guyot's first scientific work, fifty years since, and his last was mount- 

 ain work. And I think I am safe in saying that no one before him, if 

 any since, can claim to have made with the barometer more numerous 

 and more accurate hypsometric measurements ; his field books make 

 the number of such measurements by him over twelve thousand. In 

 all his explorations he manifested that unflagging energy and thor- 

 oughness which are required for accurate work. At the same time his 

 acuteness of intellect and well-furnished mind, while demanding the 

 fullest investigation for final results, led him quickly and surely in the 

 path toward right conclusions, as was strikingly manifested in the out- 

 come of those six weeks in 1838 over the glaciers. Besides these qual- 

 ities of the careful and judicious observer his ever searching mind, as 

 shown by his comprehensive views on the earth, living nature, and 

 man, was remarkable for its powers of i)hilosophical analysis and gen- 

 eralization. The combination of the thorough student of facts in nature 

 with the far-seeing student of principles and fundamental law has sel- 

 dom been more complete, and we may therefore well describe him as in 

 a remarkable degree— using his own language — "a harmonic unit." 



The two friends from Switzerland, Guyot and Agassiz, were both 

 needed by the country when they reached its shores. Each performed 

 a work among us of great service to education as well as to science, 

 and we owe them lasting gratitude. But their change of base in com- 

 ing to America gave them a position forwider influence over the world, 

 and American gratitude is not all that-is due them. 



In recognition of Guyot's services to science he was elected to hon- 

 orary membership in several learned societies, among them the Geo- 

 graphical Society of London, and that of Paris; and since his decease 

 a geographical society has been organized at ISTeuchatel, this being, in
