Sufficient materials have been collected to authorize us in 

 publishing, thus early, the first number of our "Contribu- 

 tions." The frequency of this publication will, however, 

 entirely depend upon the matter presented. • 



As we are happy to be the means of disseminating know- 

 ledge, all essays directed to us for publication will receive 

 due attention — it being distinctly understood that the so- 

 ciety do not hold themselves responsible for the accuracy 

 of declared facts. It is, moreover, our desire to establish a 

 mutual intercourse with scientific societies and individuals, 

 by inviting an exchange for such duplicates of books and 

 specimens of natural objects as we may have in our posses- 

 sion, and of which wc shall from time to time furnish cata- 

 logues.
