10 Prof. Cotta’s Eulogy on Von Buch. 
the malady with violent pains in the foot, in which for many 
years he had suffered from chilblains. -He did not afterwards leave 
his couch, and a letter from Dresden remained unread. On Tues- 
day the physiciau was called. ‘The pains had left him, but a 
general debility, a nervous excited condition, had taken their 
place. His acquaintances, however, still knew nothing of his sick- 
ness. On Wednesday, Prof. Beyrich accidentally visiting him, 
received for the first time information of the sufferings of the 
highly honored man. He found him in bed, but cheerful, and 
joking in his wonted manner, alluding often to the task he had un- 
dertaken on the chalk formation of North America, and which had. 
engaged his attention for some time past. Upon his writing table 
lay the beginning of his work with the superscription, ‘* Nebraska,” 
but under this however, were only two lines, probably written on 
Saturday. On the same evening, Prof. Beyrich carried the intelli- 
gence of his illness to the meeting of the German Geological So- 
ciety, of which von Buch was president. During the night of 
Thursday his condition became much worse. Debility and fever 
had visibly increased. However, on Thursday he could still con- 
verse with most of those who visited him during the day. When 
Prof. Beyrich visited him again at 10 0’clock on Friday, March 4th, 
he found Messrs. Ewald, Braun, and Papiz already at the couch 
where he lay unconscious, and they did not again leave it till 
his death, which occurred at twenty minutes before two o’clock. 
On March 9th the funeral solemnities took place in the dwel- 
ling of the departed, which the Royal Botanic Garden had richly 
decorated with palms and laurel. His mortal remains were then 
to von Buch’s liberality. He often came here, and only three 
years since when we celebrated the memory of his distinguished 
master, he was to our joy with us in this hall, where to-day his 
portrait presents to us only the noble lineaments which we shall 
never forget, as his whole service must forever remain unfor- 
gotten. 
An account of the origin of this portrait may not be without 
interest. L. v. Buch had often received urgent requests to allow
