his portrait to be taken, but had never consented. When his 
friend Friesleben on the remittance of his own portrait, once ur- 
gently requested his in return, he received in its stead a large lith- 
ograph of an Ammonite with the signature under it, “ Leopold v. 
Buch.” There was little hope then, of obtaining a portrait of the 
great geologist, aside from the imperfect failure in the Dictionnaire 
des Sciences Naturelles. Some years since, however, his King 
sent the celebrated portrait painter, C. Begus, to him, and told him, 
that he, the King wished his portrait. What remained for him 
todo? He must obey and sit still. From that portrait is this 
lithograph a copy. 
And now permit me to address myself to you who are dedica- 
cating yourself to the same studies which here once lured this 
distinguished man. If you all however have not proposed to 
yourselves the same course—if you are not all called to furnish 
similar results in your particular departments like a L. v. Buch, 
still may you ever take him as an exemplar. His example like 
that of Alexander v. Humboldt, and many others, teaches at the 
same time that even from an unpretending place of study great 
effects may go forth. May we all strive to imitate him in un- 
tiring zeal, system, and noble sentiments—this will be the high- 
est honor we can show to his memory. For the immortality of 
his name, he himself has provided.

Arr. Il.—F xtracts from the Report on the Geology of the Lake 
Superior Land District ; (Part Ul.) by J. W. Fosrex, and 
J.D. Wurrney.* 
Iv Part I, of this Report, communicated to the Commissioner 
of the General Land Office in 1850, and published in 1851, we 
have given a historical sketch of the. exploration of the country 
bordering on Lake Superior, a description of its physical geography 
and climate, and so much of its geology as was necessary to the 
full elucidation of the copper-bearing rocks and their relation to 
the sedimentary formations; this being the subject to which that 
part of the report was principally devoted. The two concluding 
chapters coutained an account of the drift phenomena so con- 
Spicuously displayed in the region of the great lakes. 
In Part IL, of this Report, we shall proceed to the detailed and 
Systematic description, so far as our materials will enable us,
