Sjogruvfite is a manganese arsenate, also described by Igel- 

 strom:, from the same locality. It occurs in crystalline granules 

 or seams in jacobsite. The color is light yellow, resembling 

 some garnet, but its hardness is less. An analysis gave : 



A80O5 Fe 3 O a MnO CaO PbO H 2 



49-46 11-29 27-26 3'61 1-74 6*81 = 100-17 



It is not far from other manganese arsenates actually described, 

 and it needs further examination to prove that it is a distinct 

 mineral. — Ibid.
