450 APPENDIX, &C. 



It does not fall within the scope of my plan to give 

 more than a mere list of minerals and of their primary 

 forms. Descriptions of the minerals themselves, and 

 figures of their secondary forms, as they occur in 

 nature, will form the substance of a volume on 

 Mineralogy by Mr. W. Phillips, which is now in the 

 press.
