Description:	Unbelievable occurrence of a ferric tourmaline in a granite pegmatite. The statements in Min Rec. 33:215 are insufficient to accept this identification. Optics, specific gravity, and "gemological techniques" can not be accepted as conclusive proof. Quantitative chemical analyses are necessary.
