REVIEW. 265 



Chapters V., VI., and VII. describe the older rocks, from the igneous to 

 the Silurian, ending with the Ludlow series. 



Chapters VIII., IX., and X. describe the rocks between the old red sand- 

 stone and the saliferous marls. 



Chapters XI., XII., and XIII. proceed upwards, from the oolite series to 

 the pliestocene groups. 



Chapter XIV. is devoted to the post-tertiary system, comprising the allu- 

 vial deposits, as great mosses, coral beds, and other recent accumulations. 



Chapter XV. is a general review of the stratified rocks, and the deductions 

 derived from such a review. 



Each chapter is embellished with geological sections, or well executed 

 figures of the fossils characteristic of the difi'erent strata. 



An admirable feature in the work is, a recapitulation at the end of each 

 chapter, which, while it refreshes the memory, presents the facts in other 

 and more terse language, thus tending to impress them upon the memory. 

 To give an idea of the pleasing style of the author, we quote a portion of 

 the concluding paragraph of the first chapter. Talking of the Science of 

 Geology, he says, — 



" The objects of research are scattered everywhere around us. Not a quarry by the 

 way-side, — not a railway-cutting through which we are carried, — ^not a mountain-glen 

 up which we cHmb, — nor a sea-cliff under which we wander, but famishes, when duly 

 observed, important lessons in Geology. A hammer to detach specimens, and a bag 

 to carry them in — an observing eye and a pair of wilUng limbs, are nearly all the 

 young student requires for the field; and by inspection and comparison in some 

 museum and the diligent use of his text-book, he will very soon be able to proceed in 

 the study as a practical observer. Let him note every strange and new appearance, 

 handle and preserve every new specimen with which he is not familiar — throwing 

 nothing aside until he becomes acquainted with its nature ; and thus, besides obtaining 

 additional knowledge and facilitating his progress, he will shortly acquire the invalua- 

 ble power of prompt and accurate discrimination." 



In The Naturalist for January 1855, there is an account given, by Mr. G. 

 R. Twinn, of his having met with the nest and egg of the Dipper, in the 

 county of Norfolk. As no one else has as yet commented on this statement, 

 made, it appears, in reply to the inquiries of other naturalists on the sub- 

 ject, and as a corroboration of a previous mention of the supposed fact, I 

 must express the most unqualified disbelief of any such occurrence. That 

 the nest was indeed that of an " Ouzel," I have not the slightest doubt ; but, 

 that it was not that of a " Water Ouzel," I feel perfectly certain. No doubt 

 the Water Ouzel is " more local than rare," but this in no way whatever
