ADVEETISEMENT 



FROM THE PUBLISHER. 



THERE is no department of our plan, as detailed 

 in the original Prospectus of this Work, in which 

 we have unfortunately been so far deficient, as 

 that of the subject which occupies the present 

 Volume. This has arisen from a variety of causes, 

 over which it has been difficult to exercise con- 

 troul ; but we now hope to supply the want, and 

 to do so in a more interesting manner, than if we 

 had at once availed ourselves of the hackneyed 

 examples and descriptions in the power of every 

 one. 



The volume on 



ICHTHYOLOGY 



with which we now present our Readers, will be 

 found a comprehensive digest upon the whole 

 subject, and contains, besides, an ample intro- 

 duction to the study of the various tenants of the 

 " waters under the firmament," many specimens 

 of the most useful and most wonderful forms 

 which inhabit the " great deep.'*
