bracing the new views on that subject. The several mineral species 

 are given under their alphabetical heads, with their most important char- 

 acters and analyses. 



When finished, this work will be a most complete and valuable store- 

 house, well arranged for reference, into which one cannot look without 

 finding something suited to his purpose. This edition is published in 

 numbers, twenty-four of which will complete the volume. Each num- 

 ber contains about sixty-four pages of close type, at the remarkably 

 small price of twenty -five cents each. 



14. Mr. Alger's edition of Allan's Phillips'' Mineralogy. — Mr. Al- 

 ger has been for some time engaged in preparing for the press a new 

 edition of Mr. Phillips' popular treatise on mineralogy, taken from the 

 last English edition by Allan. Much new matter and about fifty new 

 figures have been added to the " Introduction" on Crystallography, 

 besides many new original figures of species and new measurements 

 of angles. The new and modern analyses of old species have been 

 in many instances substituted for those of Vauquelin and Klaproth ; 

 while many new analyses have been made for this edition by Mr. 

 Hayes of Roxbury, Dr. C. T. Jackson and Mr. John H. Blake of Boston. 



We understand that this volume, which is nearly all printed, will be 

 published about the middle of April next. On its appearance we shall 

 notice it again. 



15. Proceedings of the Boston Society of Natural History, taken 

 from the Society' 's Records. 8vo, Boston, pp. 128, from Jan. 6th, 1841, 

 to June 21st, 1843. — This active society, whose useful labors have fre- 

 quently been noticed in our pages, has commenced the regular pub- 

 lication of its proceedings. The abstracts of papers are ably redu- 

 ced, and show that the society has an uncommon number of working 

 resident members, as well as active correspondents. We have no room 

 to quote all the passages which we had marked for extraction, in these 

 "proceedings." On p. 101, Mr. Teschemacher makes an interesting 

 communication on the origin of the valuable manure called Guano, 

 from the sea islands off the coast of Peru. We extract the passage. 



" With reference to the opinion, entertained by some, that the Guano 

 had been accumulating from a period perhaps prior to the origin of the 

 human race, Mr. T. translated the following passage from the ' Memo- 

 riales Riales 1 of ' Garcilasso de la Vega.' Lisbon, 1609, p. 102. 

 ' On the sea-coast, from below Arequipa as far as Tarapaca, which is 

 more than two hundred leagues of coast, they use no other manure than 

 that of marine birds, which exist on all the coast of Peru, both great and 

 small, and go in flocks perfectly incredible, if not seen. They are reared
