instances, given in our remarks on Classification, illustrate the 

 fact that the natural system is founded actually on chemical prin- 

 ciples." — Preface. On this side the water, the numerous geolo- 

 gical and mineralogical surveys which have been commenced or 

 brought to a close, have done much to diffuse a taste for such 

 studies among the mass of the people, and to awaken a spirit of 

 inquiry, which, under the direction of the eminent gentlemen 

 charged with the several parts of the work, has developed to a 

 good degree our mineralogical resources. " Sources of informa- 

 tion have thus been laid open for making a thorough American 

 work on Mineralogy ; and it has been the endeavor of the author 

 to avail himself fully of these various aids, to render, if possible, 

 the present treatise deserving of this title." Many new species 

 have been added to our former lists, and doubtless many propos- 

 ed which are not new. Many old ones have been made to co- 

 alesce with others previously established,* while old names that 

 had been discarded are again brought into use.f
