X LOUIS AGASSIZ. 



Since 1833 his publications have been very numerous. Among them are works on the 

 Echinoderms and on the Fossil Mollusks of the Jura, a German translation of Buckland's 

 Geology, with copious notes, and his Fresh-water Fishes of Europe. The Nomenclator 

 Zoologicus, published some years since, and the Bibliographic Generate cCHistoire 

 JYaturelle, lately published by the Ray Society, are the product of several years' obser- 

 vation. 



In 1837 Agassiz first promulgated his " Glacial Theory," which has ever since attracted 

 much attention. It having been asserted that it was inconsistent with known facts, Agas- 

 siz for eight years spent his summer vacations in making observations at the Glacier of 

 the Aar, eight thousand feet above the sea, and twelve miles from any other habitation 

 than his own hut. The result of these examinations are contained in two works, Etudes 

 sur les Glaciers, and Systeme Glaciere. 



In 1846 Agassiz came to America, and on the establishment of the Lawrence Scientific 

 School he accepted the appointment of Professor of Zoology and Geology, which he still 

 holds. Since his arrival in this country, Professor Agassiz has presented a large number 

 of communications to the American Academy and other scientific bodies, and has pub- 

 lished, in connection with Dr. Gould, of Boston, a Zoology for students. His elaborate 

 work on Lake Superior has just appeared.
