704 MEMOIR OF GUYOT. 



Society of the Natural Sciences for November, 1843, May and December, 

 1845, aud January, 1847.* 



Guyot reserved the complete report for the second volume of Agas- 

 siz's great work on glaciers. But, unfortunately, after the first volume 

 by Agassiz appeared at Paris, in 1847, there came tlie revolution of 

 1848, which put an end to their plans. 



The study of the geological structure of the Jura Mountains, in 

 which he worked out the system in the flexures of the strata and proved 

 that it must have been produced by lateral pressure, was another of 

 Guyot's labors soon after his return from Neuchatel, although not re- 

 l)orted on until 1849, at the Cambridge meeting of the American Asso- 

 ciation.! 



Guyot had been teaching at Neuchatel nine years when suddenly the 

 ''Academy" was suppressed by the grand revolutionary council of 

 Geneva of 1848. The 13th of June brought the tidings, and on the 

 30th the end came "without any indemnity to the professors." Letters 

 from Agassiz urged him to come to America. Though reluctant to take 

 the step because of the many ties of friendship and association that 

 bound him to Switzerland, and especially on account of the family 

 under his charge, consisting of his mother, then seventy years old, 

 and two sisters, which he should have to leave behind, he had the de- 

 cision of his mother, after her careful reading of Agassiz's letter, in favor 

 of it, I and in the following August he left friends, home, and Europe. 



In America. — The Lowell Lectures at Boston — ^^JEJarth and Man^^ — 

 1848, 1849. — Without English speech, with no plans ahead, and with 

 more than forty years of his life behind, a crowd of apprehensions con- 

 tinued to haunt Guyot until he reached the American shores. Once 

 landed in New York, he was soon after at Cambridge with his friend 

 Agassiz; and from that time the calamity that had befallen him, com- 

 menced to prove itself a blessing. It was for him, falling in with the 

 " geographical march of history," aud coming to the land and ''•peoi)le 

 of the future," where no ijolitical or religious shackles were in the way 

 of success, and where an audience as wide as the continent was ready 

 for whatever he had to communicate. 



In September, a fortnight after his arrival, Agassiz took Guyot to the 

 meeting of the American Association at Philadelphia. At its close he 

 made his first journey to the Alleghauies, spending a week in crossing

}; August 8th, 1848, the day of his departure from Neuchdtel, he writes: "Ma 

 nifere a 6t6 toujours si forte et si confiaute qu'elle m'a souteuu jusqu'au dernier mo- 

 ment, mais son dernier sanglot, en me quittaut, m'est alle au ccour: Oh! que Dieu 

 me donne de la revoir et d'embellir ses derniers jours." This desire was realized. In 

 the autumn of 1849 he had the happiness of welcoming his mother, two sisters, aud 

 a niece to the new home which he had prepared for them in Cambridge.
