on Vespertiliones is strictly criticised, so far as concerns the European 
species, and some mistakes which had slipped into it are corrected ; how- 
ever, the reviewer has on this occasion forgotten, that these corrections 
were already made by Keyserling and Blasius, in our Archives, two years 
previously. Notwithstanding these little criticisms, we hail with plea- 
sure the continuance of this annual report, as by its means we become 
more readily and perfectly acquainted with Italian contributions to science ; 
and we have only to express a wish, that the celebrated author may fill up 
omissions, by the aid of our Archives, which otherways might occur in 
the sketch of German literature.

No reports of the Transactions of British and Scandinavian Natu- 
ralists have yet reached me, so that I must here leave a gap. These 
Societies, if they had any anxiety that their Transactions should early 
become known to us, might lessen the trouble of editing, if they them- 
selves would timeously forward their Reports, or, at least, send them 
over to the Academies.

In the introductory discourse by Schinz, some interesting statements 
are made of the condition of Scientific Institutions ui Switzerland, which 
furnish an obvious proof of what great progress can be made in this 
department, when the work is set to with will and energy. In the for- 
mation of large collections, Geneva, Neuenburg, Zurich, Basle, Berne, 
and Aargau, have especially taken the lead. Lucerne and Freiburg have 
shown a preference for other objects.
