T MINERALOGY. 



HE Journal de Vbyjique (Brumaire, an lo.) contains a 

 notice of the difcovcry of corundumj at Cbcfnut Hill, near 

 Philadelphia, by Dr. Scybert. From a few experiments upon 

 the mod obvious properties of a ipecimcn received from the 

 difcoverer, made by Mr. Richard Phillips, to whom we are in- 

 debted for the prefent article, he is induced to believe that it is 

 not corundum : it has for matrix decompofed felfpar, accom- 

 panied by white fell par and mica ; oni vone cryftal was contained 

 in the fpecimen,whofeform was fufliciently determinate for de- 

 fcription ; it appeared to be a comprcired hcxaedral prifm, having 

 one of its fides interrupted in cryftallizing; its colour inclining 

 to green ; its hardnefs fufficient to give fire with Heel, and to 

 fcratch glafs ; but it is itfelf cafily fcratched by corundum, 

 and is not hard enough to mark the beryl ; whereas the latter 

 is readily fcratched by corundimi. It is eafily reduced to 

 powder. Its fpecific gravitv only 2,70, that of corundum 

 being 3,87 : the quautitv was too fmall to allow of accurate 

 analyfis; upon examination it would probably be found to b« 

 quartz, which it nearly rcfembled in fra6lure, deriving its 

 colour from oxide of iron. 



The following account of the dlfcovery of a mine of 

 native fulphur in the Lower Pyrenees has juft appeared in 

 one of the French journals, in a letter from Dr. Thore, 

 *' Permit me to announce, through the medium of your 

 iournal, the difcovcrv made fonic time ago of a mine of native 

 fulphur, by a proprietor in the commune of Saint Boue, de- 

 partment of the Lower Pyrenees. Accident, the grand author 

 of difcoveries, was the author of the one in queftion. 



" Some works undertaken for repairing a water-mill laid 

 open at firli a quarry of gvpfum, and loon after the mine to 

 which I here allude. When informed of it, I repaired to 

 the fpot to obtain the ^leceflary information refpeiting it ;
