REPORT OF THE SECRETARY. 45 



second class of the college of Neucbatel in 1821, goiug thence to Carls- 

 riihe (where, in 1825, he formed an intimacy and lasting friendshii) with 

 Agassiz), afterward to the classical gvmuasium of Stuttgardt, retnrniiig 

 to Neuchatel in 1827. In 1829 he entered the university at Berlin, from 

 which institution he received the degree of Doctor in Philosophy in 1835. 

 The next four years he spent in Paris, making summer excursions of 

 physiographical observations through France, Belgium, Holland, and 

 Italy, and in 1838 studying glaciers in Switzerland, and investigating 

 the distribution of erratic bowiders. In 1839 he was made professor of 

 history and physical geography at Neuchatel, where his early friend 

 Agassiz had already for some half a dozen years been professor of 

 natural history. Dr. Guyot held this position for ten years, assisting 

 Agassiz in the " Systemo Glaciaire," published in 1817. 



In 1848, Dr. Guyot, at the urgent solicitation of his friend Agassiz, 

 came to this country — the latter having been here already about two 

 years. He was employed for six years by the Massachusetts board oi' 

 education us lecturer to the normal schools of the State on geography 

 and its methods of teaching. In 1849 a course of his lectures in French 

 on " The Earth and Man " were published in an English translation by 

 Professor Felton. 



In 1850 he was invited by the Smithsonian Institution to assist in 

 developing the system of meteorological observations for the North 

 American continent, then recently organized. In addition to valuable 

 suggestions in consultation with other eminent meteorologists, as a 

 needful reference work in the labor of the various reductions from ex- 

 tended observations, Dr. Guyot undertook the collection, computation, 

 and arrangement of a series of graduated tables of constants — physical 

 as well as meteorological — for the use of those engaged in such investi- 

 gations. This valuable work, comprising 212 printed pages, together 

 with "Directions for Meteorological Observations," comprising 70printed 

 pages, mainly by the same author, was published in 1852, as the first 

 volume of the " Smithsonian Miscellaneous Collections," and at once 

 became in great demand. 



Dr. Guyot at this time made a careful study of the physical geography 

 of the eastern portion of our country from Maine to South Carolina. 

 In 1854 he was elected profesfH)r of geology and physical geograi)hy in 

 the College of New Jersey at Princeton, a chair which he held till the 

 time of his death, a period of thirty years. A second edition of his 

 standard work, the " Tables," amended and greatly enlarged, was pub- 

 lished by the Institution in 1857, and a third edition in 1859, which ex- 

 tended to G38 octavo pages. 



He was one of the original members of the National Academy of 

 Sciences at its organization in 18G3. In the i)reparation of Johnson's 

 ''New Universal Cyclopaedia," a very elaborate and valuable work in 

 four large and closely printed volumes, i)ublished in 1875-78, he was 

 Dr. Barnard's assistant editor-in chief. Indefatigable in his eiiorts to
