NOTES. $17 
of Carolina, published by Mr. Curtis; those of Java, collected by 
Mr. Zollinger, at Junghuha; those of Bahia, by Mr. Blanchet; 
those of Mexico, Guadaloupe, ete., ete., and a large number that 
have not yet been published. 
As to the lichens, there are thirty-five or forty enormous pack- 
ages classified by genera, in which are contained not only all 
those which have served for his “ Botanicon Gallicum” but those of 
Nees v. Esenbeck, Flowtow and others; besides large invoices 
of exotic and European lichens from Nylander, Körber, Zollinger 
and others. The Hepatic of Nees on which the genera and 
species of the Hepaticology of this savant have been established, 
not perfectly in order, are contained in twenty-six packages, 
classified and labelled, and one package not classified. Lastly the 
alge, studied with the greatest care, for his ‘‘ Botanicon” and 
subsequent works, either by himself or Mr. Cronan of Brest, 
enriched with a large number of drawings, composing thirty-five 
to sixty packages, in which are comprised the alge of Australia, 
Ceylon, the Pacific, United States (by Harvey) ; other specimens 
from various countries sent by various savants; the microscopic 
species of Brebisson and other micrographers. To all this must 
be added twenty-four cartons from M. Lamy de Perignam, con- 
taining many different cryptogams, studied and named by M. 
Montague, de Brebisson, etc. 
All these treasures which he has been accumulating for fifty 
years, and prepared for special work of his own, but which the 
study of bryology has caused him to abandon, he will sell for five 
thousand francs. 
As to the mosses the collection is still larger, but he will only 
sell it on condition that it shall remain in his hands during his 
life. 
We hope the time is coming when rare scientific treasures like 
these will be presented either to the Cambridge, or some other 
accessible herbarium in the United States, by generous persons of 
means. 
We reprint, from the “ N. Y. Tribune,” a portion of the report 
by Prof. E. Weiss of Vienna, who visited this country in 1872 for 
the purpose of acquainting himself with the condition of practical 
astronomy in the United States. The extract well represents 
Some of the causes that retard original investigation in the United
