by the traveller in a Guide book, than any similar work hitherto 

 published. In short, we consider it as our best Guide to the 

 Highlands of Scotland. 



4. Recherch£s sur les Poissons Fossiles. Par L. Agassiz. Neuchatel. 

 1834. 4to, with Coloured Plates. 



In this work it is intended to give not only a description of 

 all the fossil species hitherto discovered, but also to combine 

 with it a general outline of the characters of the orders, families, 

 and genera of all living fishes. At the same time, the first vo- 

 lume will contain a full anatomical description of the scales, the 

 skeleton, and the teeth, and a comparison will be made with the 

 other classes of the animal kingdom. 



In the geological account of fossil fishes, the most remarkable 

 organic remains of other classes, which are found associated with 

 them, will be mentioned, in order to point out the character of 

 the various geological periods, and to indicate the changes which 

 have occurred in the order of succession of animals. 



It is thus evident, that the work is intimately connected with 

 zoology as well as with anatomy and geology. But for far- 

 ther information on this subject, we must refer our readers to 

 the preface to the first part. 



The Geological Society of London, impressed with the im- 

 portance of M. Agassiz"* researches, accorded the highest mark of 

 its approbation and encouragement, by decerning to him the 

 Wollaston medal in 1834. 



We are also happy to announce, that the British Association, 

 during its late meeting in this city, was so fully aware of the 

 value of the researches of M. Agassiz on fossil ichthyology, and of 

 the important results to be obtained from them for geology, that 

 it voted a sum of 100 guineas for the encouragement of this 

 branch of zoological science in Great Britain. 



Two numbers have already been published, of which we shall 

 soon give a detailed account. 



New Work on Geology. 

 We learn with pleasure that Professor Phillips has now in 

 the press a Guide to Geology, the object of which is to give 

 the elementary facts and generalizations, and to furnish correct 

 information as to the modern and actual state of the science.
