American Academy of Arts and Sciences of Boston, etc., and author of 



U A System of Mineralogy." 



DURRIE & PECK, of New Haven, have just published the 

 above Manual. 



It is intended to fill a vacancy hitherto existing in the means 

 of instruction upon the important and popular topics of which it 

 treats. Most of the works already in use are either so full, vo- 

 luminous, and technical, as to embarrass and discourage the 

 young student ; or so very superficial and meager as to fail in 

 the end of imparting instruction or exciting the interest of the 



pupil. Those minerals which are most important, including all 



of American origin, are fully dwelt upon; and the rarer and less 

 important are only briefly noticed, in smaller type. Wherever 

 an opportunity has offered to give facts of a practical character 

 connected with mining and the arts, it has been made use of; 

 and it is believed that the work will in this respect be an accep- 

 table addition to the library of the more advanced student, as 

 well as of those interested in the discovery, examination, and 

 reduction of ores.

 ralogieal Science are treated of under the appropriate heads in
