19. Dr Thomson? 's Narrative of a Journey through the Moun- 

 tains of Northern India during the years 1847—8. — This valuable 

 and deeply interesting work, of which more on a future occasion, 

 we very earnestly recommend to the attention of Naturalists and 

 Geographers. Many of the books of travels supplied by the press 

 are harmless evanescences, forming a striking contrast to the endur- 

 ing pages of Dr Thomson. 



20. Professor Charles Upham Shepard's Treatise on Miner- 

 alogy. — The mineralogies of Cleaveland, Alger, and Dana, are well 

 known, and highly esteemed in this country, and so also is that of 

 Professor Shepard. We have now before us Part 1st of the 3d edi- 

 tion of that valuable work, which we strongly recommend to the stu- 

 dents of Mineralogy, with the remark, that the course pursued by 

 Professor Shepard in his Mineralogy, is worthy of adoption by other 

 mineralogists at no great distance from us. 



21. Humboldt* s Cosmos. — All will rejoice to learn that the 

 illustrious Humboldt has recovered from his late indisposition, and 

 that this extraordinary man, although about 83 years of age, is now 

 actively employed in preparing the fourth and last volume of his 

 renowned work, Cosmos. 



22. Silurian System. — Sir R. I. Murchison is preparing a new 

 work on his Silurian System. 



23. Bischof's Chemical Geology. — An English edition of this 

 celebrated work will soon appear under the patronage of the Camden 

 Society. 



24. Professor Bischofs Work on Natural Science. — A third 

 edition of this excellent popular view of Natural Science has just 

 appeared in Germany. A translation of it would, we are convinced, 

 be favourably received by a numerous class of readers in this country. 



25. Map of the Distribution of Plants and Animals. — Professor 

 Edward Forbes exhibited and explained to the meeting of the British 

 Association in Belfast, a very interesting map illustrative of the dis- 

 tribution of Organic Beings throughout the land and waters of our 

 planet. This map, we understand, is to be engraved and published 

 by Mr Keith Johnston of Edinburgh. 



26. Smithsonian Contributions to Science. — The third and fourth 

 volumes of this valuable work, presented by the Smithsonian Insti- 

 tution to the Wernerian Society, have just been received. The con- 

 tents of these volumes are as follow : —
