various selenides of silver, copper, and lead from the Cerro de Caclieuta, 

 Mendoza, Argentine Eepublic; it has resulted from the alteration of 

 these minerals. 



Cobaltomenite. — According to Bertrand this is a cobalt seleuite from 

 Cacheuta, in the Argentine Republic. It occurs in minute rose-red crys- 

 trals, resembling erythrite in appearance. 



Cossynte. — A mineral near amphibqle in form, but triclinic in form 

 and having a prismatic angle (cleavage) of only 114o. In composition 

 it approaches some very ferruginous amphiboles. Described by Foerst- 

 iier as found imbedded in the liparite lavas of the island of Pantellaria 

 (ancient name Cossyra). 



Craigtonite. — A name given by Heddle to a blue-black substance 

 forming dendritic stains on red granite, in the quarry of Craigton, Hill 

 of Fare, Aberdeenshire, Scotland. An analysis gave alumina, iron 

 sesquioside, manganese protoxide, magnesia, and alkalies. It is not a 

 mineral, and the name deserves no recognition. 



Gyprusite. — A supposed new iron sulphate of doubtful character; de- 

 scribed by Eeinsch. It occurs in larger quantities in an impure con- 

 dition incrusting the side of a hill in the western part of Cyprus. It is 

 soft, chalk-like in consistency, and of a yellowish color. 



Destinezite. — Announced by Forir and Jorissen as a new iron j)hos- 

 phate related to delvauxite, but not yet fully described. It is from the 

 ampelite of Argenteau, Belgium, and occurs in yellowish-white, nodular 

 masses of earthy aspect. 



Bouglusite. — A hydrous chloride of potassium and iron from the salt 

 mines of Douglass hall, Germany; described by Ochsenius and Precht. 

 It seems to be essentially the same as the Yesuvian mineral called 

 erythrosiderite by Scacchi. 



Dumortierite. — A silicate of alumina occurring in prismatic crystals 

 of a light blue color, also in fibrous forms imbedded in blocks of gneiss 

 at Chaponost near Lyons, France. Named for the paleontologist, M. 

 Eugene Dumortier. 



Edmonsonite. — A compound of nickel and iron identified by Flight in 

 the meteoric iron of Melbourne, Australia, and regarded as a new and 

 distinct mineral. 



Ellonite. — A name attached by Heddle to a pale yellow unctuous pow- 

 der fi'om the gneiss of Ellon, Aberdeenshire, Scotland. It is an impure 

 hydrous silicate of magnesia, not a distinct mineral. 



Enophite. — A name given by Schrauf to a chloritic variety of serpen- 

 tine, related to the hallite of Cooke. The specimens analyzed were 

 from the serpentine region of Southern Bohemia, near Budweis. 



Erilite. — A name given by H. C. Lewis to minute acicular crystals 

 occurring as inclusions in quartz from Herkimer County, New York. 

 Their chemical nature was not determined; there is every probability 

 that they belong to some well-known species. 



Erytlirozincite. — A mineral occurring, according to Damour, in thin
