		The smaller coastingsteamers call, and there is an active trade with Chios and Smyrna.ERYTHRITE, the name given to (I) a mineral composed of a hydrated cobalt arsenate, md (2) in chemistry, a tetra- hydric alcohol.
		The name erythrite, from ~pvOpc, red, was given by F. Beudant in 1382.
		Theinternally compensated modification, i-erythrite, correspondingto mesotartaric acid, occurs free in the algae Protococcus vulgaris, and as the orsellinate, erythrin, C4H6(OH)2(O.C5H703)2, in many lichens and algae, especially Roccella montagnei.

		(2) The alcohol erythrite has the constitutional formula HO•H2C•CH(OH)•CH(OH)•CH2OH; it is also known as erythrol, erythroglucin and phycite.
		Energetic oxidation gives erythritic acid and mesotartaric acid.
		i-Erythrite and the racemic mixture of the dextro and laevo varieties were synthesized by Griner in 1893 from divinyl.

	ERYTHRITE Chapter 25. Arsenates, arsenites, phosphates, and vanadates
		Erythrite, a cobalt arsenate hydrate mineral, was reported from Franklin by French (1953).
		Hendricks (1960) reported it as light violet red clusters of fibrous crystals, associated with galena, calcite, and malachite on a specimen from Mine Hill.
		Erythrite has been found sporadically in minor amounts at Sterling Hill, where it occurs as bright pink to light pink clusters (0.5-1.0 mm) of microscopic crystals on fracture surfaces in franklinite/willemite ore. It has also been found as pink 1-2 mm rosettes with epidote on the 1400 level; this material has CoO > 25 wt.

	ANNABERGITE Chapter 25. Arsenates, arsenites, phosphates, and vanadates
		Annabergite occurs as a whitish powdery encrustation on fluorite, associated with pimelite and nickel arsenides from the Trotter Shaft at Franklin.
		Because annabergite is not unambiguously differentiated from erythrite by X-ray methods alone, the identification is tentative.
		However, the assemblage is Co-rich at its outer extremities where the probable annabergite powder occurs, and thus the unanalyzed material could possibly be nickeloan erythrite.
