shores of the Arctic Sea. To the westward these rocks are skirted by 

 a broad belt of Silurian rocks, which form the western shore of Lake 

 Winnipeg, and these, again, are succeeded in a westerly direction by 

 beds of Devonian age, — the two series forming the broad and nearly 

 level district between Lake Winnipeg and the first range of hills. 

 The base of these hills is also formed by Devonian rocks, from which 

 salt-springs issue in many places, and are worked with considerable 

 profit, although in the rudest fashion. No traces of Carboniferous, 

 Permian, Triassic, or Jurassic rocks were detected by Mr. Hind, who, 

 however, states that, in the sections examined by him, a portion 

 amounting to about 400 feet, between the Devonian rocks below and 

 the Cretaceous above, was inaccessible in consequence of its being 

 covered by drift. The most remarkable feature in the geology of 

 Rupert's Land is the great development of the Cretaceous series of 

 rocks, which form the capping of the hills just mentioned as lying 

 to the westward of Lake Winnipeg, and extend therefrom in a 

 wide plateau, broken here and there by small hills, to the Grand 

 Coteau du Missouri, which they form, and beyond which, in the 

 territory of the United States, they are covered by the Tertiary beds, 

 occupying the greater part of the valley of the Missouri River. 

 Northward these rocks have been traced beyond the north branch 

 of the Saskatchewan River, and their further extension is unknown. 

 Tertiary beds, the search for which was of importance from the 

 circumstance of the occurrence of lignite in them, both in the basin 

 of the Missouri and that of the Upper Saskatchewan, were not met 

 with in the region explored by the expeditions, although rolled frag- 

 ments of lignite were often met with in abundance in the river-sec- 

 tions of recent deposits. 



With these remarks we take leave of Mr. Hind's narrative, of 

 which we hope we have said enough to indicate that it contains 

 a great amount of highly interesting information. It is illustrated 

 with numerous excellent woodcuts of localities, Indians, articles of 

 dress, and fossils, and with several maps and geological sections. 



Tabular View of the Orders and Leading Families of Myriapoda, 

 Arachnida, Crustacea, Annelida, and Entozoa. Society for Pro- 

 moting Christian Knowledge, London, 1861. 



The title conferred upon this little book by its publishers is 

 hardly, to our notions, expressive of its contents ; it is rather a pic- 

 torial than a tabular view of the Annulose division of the animal king-, 

 dom, exclusive of the Insects and Rotifera, and consists of four large 

 mounted folding plates of characteristic forms of the classes mentioned 

 in its title. These plates are also sold mounted on a roller and 

 varnished, so as to form a diagrammatic illustration of the great group 

 of Annulosa, with the omission, as above stated, of the important 

 class of Insects, which may probably be intended to form the sub- 

 ject of a similar publication. 



The subjects in the present work have been arranged, as stated on 

 the last plate, by Mr. Adam White and Dr. Baird — the former taking
