406 Miscellanies. 
nected with the University at Heidelberg, which for the present has 
been placed under my direction, is desirous of making exchanges of 
objects in Natural History, and more especially in Zoology, with 
some similar public institutions, or private individuals, in the United 
States. The number of specimens from the United States, at pres- 
ent in this country, is so very small, that duplicate specimens of any 
and every object, even the most common and least valued, would be 
acceptable. A list of desiderata is therefore unnecessary. Every 
thing that may be sent will here be highly valued. It may be re- 
marked, however, that the packages should be large, in order to be 
proportioned to the expense of transportation, and also that the spe- 
cimens should be well preserved and carefully secured. 
There may be perhaps some persons, friends of science, now ab- 
sent from Europe for a time, who, considering the many difficulties 
which this museum must encounter in procuring objects in Natural 
History from the various parts of the globe, may feel inclined to 
transmit to us, without a compensation in return, collections of shells, 
insects, crustacea, arachnides and other objects, which sequins but 
litle care in their preservation.* 
The society or societies, which may be dueond to peace of our 
invitation, are requested to name their desiderata; and also those 
who have specimens for sale, are desired to send us a list of them, 
with the prices attached. 
All objects intended for the museum may be transmitted to Mr. Ph. 
Lajeune, of N. York; or Messrs. Wanner, Langest & Co., at Havre. 
» The museum would also offer to expose for sale any ob- 
jects that may be sent out with,that design ; and if it is desired to 
establish in Germany a place of depot for the sale of American ob- 
jects in Natural History, we would strongly recommend Heidelberg 
as peculiarly favorable, it being situated in the most frequented part, 
and on the most travelled route of Germany ; and moreover, it con- 
tains at present no similar establishment. We would correspond 
farther on this subject with any who may be pleased with this project.

* For the preservation of insects, pebpicsees crustaceous animals, small reptiles 
and fishes, it is sufficient to put them in bottles or small kegs filled with rum, or 
with alcohol diluted one half with vali and so securing them as to prevent their 
moving. Previous to sending them, this vessel should be carefully enveloped.
