4. The variety Fowlerite occurs at Hamburgh, (N. J.) at the Frank- 

 lin furnace, where it exists in the form of a bed in limestone, along with 

 Magnetic Iron, Franklinite and Garnet. It also occurs at Sterling, 

 (the variety which has been called Silicate of Manganese,) in a bed of 

 Franklinite with Troostite, Automalite and Red Zinc-Ore ; and again at 

 Cumberland, (R.I.) where it is associated with Yenite. 



The old variety, called Red Manganese, and Manganese Spar, is found 

 at Longbanshytta in Sweden, in beds of iron-ore ; near Elbingerode in 

 the Hartz ; in the district of Catherinenberg in Siberia ; also near Cal- 

 lington in Cornwall. In the United States, it has been found abundantly 

 at Cumminglon, (Mass.) where it exists in large, rolled masses, dissemi- 

 nated through the soil. The varieties called Allagite, Corneous Manga- 

 nese, Photizite and Rhodonite, occur near Rabeland in the Hartz. 



5. It is cut and polished by the lapidary, and employed for inlaid work. 



6. It is difficult to decide whether Manganese Spar is -with greater 

 propriety placed within the genus Parachrose-Baryte, than in that of 

 Augite-Spar. Its specific gravity, color, and liability to grow darker, 

 from exposure to the weather, however, rather favor the disposition here 

 made.
