 T nomenclature proposed by Mohs, presents a very uncouth 

 appearance when translated from the German into our less 

 pliant language ; and is moreover wholly destitute of that con-

 in these advantages, which have exerted such an important 

 influence upon the progress of those sciences, has been the 

 design of the author in offering the following system of mine-

Th menl of the species is in general similar to that
