406 MisceUanies. 



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 ma:y 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 require but 

 little care in their preservation.* 



The society or societies, which may be disposed to accept 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 &6 Co., at Havre. 



P. S. 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, arachnides, crustaceous animals, small reptiles 

 and fishes, it is sufficient to put them in bottles or smnll kegs filled with rum, or 

 with alcohol diluted one half with water, and so securing them as to prevent their 

 moving. Previous to sending them, this vessel should be carefully enveloped.
