Native Copper, Ores of Copper, and other Minerals. 107 



This specimen is fossilized in grey limestone, the body con- 

 tracted so that the buckler is nearly parallel with the back ; this 

 has rendered two drawings necessary in order to give a represen- 

 tation of both the head and abdomen, each of which is charac- 

 terized by some peculiarities not common in this genus. 



It is named after one, whose works on geology and fossil 

 organic remains, have given him an enviable station in the scien- 

 tific world.

 other Minerals found in the vicinity of New Brunswick, New 

 Jersey ; by Prof. Lewis C. Beck. 



Although many of the ores of copper are found quite abun- 

 dantly in various parts of the State of New Jersey, and extensive 

 mining operations evince the high expectations which have been 

 entertained of their value, I am not aware that any detailed de- 

 scription of them has been published. A brief and general ac- 

 count of them is given in Gordon's Gazetteer of New Jersey, 

 and in Prof H. D. Rogers's report of the geological survey of 

 that State, made in 1836 ; and some of them are also noticed in 

 the general mineralogical works. Having been engaged at in- 

 tervals, for some time past, in studying the minerals found in the 

 vicinity of New Brunswick, and the copper ores of the State 

 generally, I propose to give the results of my observations and 

 analyses. I offer them, however, as mere notices, and not as a 

 complete account of these minerals.
