LOUIS AGASSIZ. 489 
giving himself with ardor to the duties of his professorship, 
it was surely enough if he could do the author’s share in the 
production of his great works on the fossil and the fresh- 
water fishes, without assuming the responsibilities and cares 
of publication as well, and even of a lithographic establish- 
ment which he set up mainly for his own use. But he carried 
on, pari passu, or nearly so, his work on fossil Mollusca, — 
a quarto volume with nearly a hundred plates, — his mono- 
graphs of Echinoderms, living and fossil, his investigations of 
the embryological development of fishes, and that laborious 
work, the ‘“ Nomenclator Zodlogicus,” with the ‘ Biblio- 
graphia,” later published in England by the Ray Society. 
Moreover, of scattered papers, those of the Royal Society’s 
Catalogue which antedate his arrival in this country are more 
than threescore and ten. He had help, indeed ; but the more 
he had the more he enlarged and diversified his tasks, Hum- 
boldt’s sound advice about his zoological undertakings being 
no more heeded than his fulminations against the glacial 
theory. 
In the midst of all this, Agassiz turned his glance upon the 
glaciers, and the “ local phenomenon” became at once a cos- 
mic one. So far a happy divination; but he seems to have 
believed quite to the last that not only the temperate zones, 
but whole intertropical continents — at least the American — 
had been sheeted with ice. The narrative in the first volume 
will give the general reader a vivid but insufficient conception 
of the stupendous work upon which he so brilliantly labored 
for nearly a decade of years. 
Calum non animum mutant who come with such a spirit 
to a wider and, scientifically, less developed continent. First 
as visitor, soon as denizen, and at length as citizen of the 
American republic, Agassiz rose with every occasion to larger 
and more various activities. What with the Lowell Institute, 
the college in Charleston, South Carolina, and Cornell Uni- 
versity, in addition to Harvard, he may be said to have held 
three or four professorships at once, none of them sinecures. 
He had not been two months in the country before a staff of 
assistants was gathered around him and a marine zo@logical
