TO CORRESPONDENTS. 
<c On the Nature and Uses of the Primaeval Vegetation of the Earth,” by Robert Dickson, 
M.D., F.L. S., in our next. 
We have been disappointed in our expectations of presenting our readers with a wood en¬ 
graving and description of an Encrinite discovered at Frome, in the present Number; 
it will, however, appear in our next publication. 
The arrangements necessary for effecting a complete and comprehensive glossary of scien¬ 
tific terms in the several departments of Natural History, have occupied more time 
than we contemplated ; but we hope, ere long, to be enabled to fulfil our promise. 
A Review of Swainson’s “ Natural History and Classification of Birds,” in our next. 
Communications and Boolcs for Review to be addressed to the Editors 
of “ The Naturalist,” to the care of Mr. Groombridge , Paternoster-row , 
London .
