BOTANICAL INFORMATION. 89. 
academical duties required my whole attention, and prevented me from 
accepting any of the more lucrative places which from time to time 
became vacant. Thus it happens that, since Government has de- | 
prived me of the Professorship, my circumstances are such as compel | - 
me to part with my Library and Herbarium. . Having no prospect of — 
a pension, and no desire to solicit favours in high places, I address 
myself to the Members of the Academy and to my friends and con- 
temporaries, requesting their aid in trying to dispose of my collections. 
If my Library and Herbarium could be sold as a whole, I should be 
able to realize their value, and should consider the amount as an 
acknowledgment of thirty years of academical services. The Herba- 
rium consists of 297 volumes in folio and 42 volumes in guarto, and 
contains 80,000 sheets. It is valuable on account of its consisting  !. 
chiefly of exotic specimens, including plants collected by Sieber, Preiss, — 
Wallich, Wight, Ecklon, Zeyher, Drége, Pappe, Wied, and others, and 
representing most fully the Floras of Mexico, New Holland, North oe 
America, Brazil, Southern Africa, the East Indies, and Europe. It is 
rendered still more important by its ‘containing the original specimens 
on which my monographie labours, the dissertations on the Laurinea, 
Solanee, Acanthacee, Hepatice, Asteraceae, Cyperacee, Graminee, and 
Restiaceæ, are founded. The Library is .composed of 3,000 volumes, - 
embracing the standard works on Natural History and Natural Philo- 
sophy. It is to be sold in Breslau on the first of May, 1852, by 
public auction, and commissions will be received by the Schletter’sche - 
Buchhandlung in Breslau, or any other great bookseller on the Con- | 
tinent. ae 
“The Herbarium, if it cannot be sold entire, is to be disposed 
in sets. It has been valued at 12,000 thalers;—the Zowrineæ at 
280 thalers, the deanthacee at 600, and the Glumacez at 3,000 "
