BLEMYES, or Blemmyes, an ancient nomadic race of Africa, who appear to have occupied different regions at different epochs. In Ptole- my's time they held the territory between the Astaboras (Bahr-el-Azrek) and Astapns (At- bara). Older authorities speak of them as ex- tending beyond the desert of Libya. In the 2d century A. D. they had become very powerful about the borders of Egypt, then under Roman rule, and even made warlike and predatory expeditions into the province. Diocletian made extensive concessions to their powerful chiefs, and gave up to them the parts of N ubia held by the Romans. They continued their hostile expeditions, however, and as late as the 7th century molested the inhabitants of the territory about them. Several ancient writers represented the Blemyes as a fabu- lous race, and many stories were current of their savage and ferocious appearance and habits. The Bishareen, Ababdeh, and other tribes of the present day are supposed to be their descendants. BLENDE (Ger. blenden, to deceive), a com- mon ore of zinc, so named because, while often resembling galena, it yielded no lead, and thus deceived the miners. Another name for it is sphalerite, from a<t>a).ep6f, treacherous. When pure it is composed of sulphur 33, zinc 67= 100 ; but part of the zinc is often replaced by iron, and occasionally by cadmium. It some- times occurs in brilliant tetrahedral crystals, also fibrous, radiated, and massive. Its lustre is resinous to adamantine; color brown, yel- low, black, red, green white or yellow when pure. The English miners call it blackjack. Blende is found in both crystalline and sedi- mentary rocks, usually associated with galena, also with barite, fluorite, siderite, and ores of silver. It abounds with the lead ore of Mis- souri, Wisconsin, Iowa, and Illinois, and has been found in many other localities in the United States. Derbyshire, Cumberland, and Cornwall afford different varieties;, also Tran- sylvania, Hungary, the Hartz, Sahla in Swe- den, and many Saxon localities. Owing to the difficulty of working this class of ore, it was formerly allowed to accumulate about the mouths of mines, and was not economized for zinc. In modern times, with improved metal- lurgical processes, zinc is largely made from
