TO CORRESPONDENTS. 
We have to acknowledge the receipt of numerous Contributions, the insertion of which are 
unavoidably postponed for the present. To our esteemed Correspondents an apology is 
due for the omission of a separate Notice of their several Communications. 
A Review of the second Part of the first Volume of “ Transactions of the Geological Society 
of Pennsylvania,” and Eyton’s “ Rarer British Birds,” in our next. 
The late arrival of our French and German Periodicals compel us to omit many interesting 
extracts from the Foreign Scientific Journals. 
iggr When our arrangements are completed, we propose devoting about four pages in each 
Number of “ The Naturalist” to a Glossary of scientific terms used in Zoology. 
The Glossary will be paged consecutively, for the purpose of being bound in a separate 
volume, and will form, when concluded, a valuable Text Book. 
Errata —Page 6, line 28, “ for what,” read “ for in what.” Line 29, for “ principal,” read 
“ principle.”
