Oe, is the sonrce of the new alcohol. What becomes of the other con-* 

 stituents of the oil, glyceryl, &c,, is not stated. The new alcohoMs a 

 transparent oleaginous liquid, having an agreeable aromatic odor \ its 

 density is 0823 at 19° C, it boils without decomposition at 180^ C, un* 

 der a pressure of 760^\ The density of its vapor is 4-49=r4 vol. 

 Sulphuric acid dissolves the oil and yields soluble salts of lime and ba- 

 ryta; on heating, the acid transforms the alcohol into a hydro-carboa 

 isomeric with defiant gas: this carburet is very fluid, lighter than wa- 



ter, burns with a beautiful flame and boils without decomposition at 

 125" C, : its formula is Ci 6 Hi 6 ; the density of its vapor is 3'86=r4 vol. 

 Fused chlorid of zinc produces with the new alcohol various isomeric 

 carburets of hydrogen ; chlorid of calcium dissolves in it and furnish- 

 es beautiful transparent crystals which are again decomposed by water 

 Or heat- Acetic and chlorohydric acid transform the alcohol into ethers 

 which have an agreeable aromatic odor; nitric acid when dilute con- 

 verts the oil wholly into a volatile liquid acid, but the prolonged action 

 of the acid gives pimelic, lipic, succinic and butyric acids. Potash 

 lime at a temperature above SSO'^ C, converts the oil with disengage- 

 ment of hydrogen into a volatile acid which remains combined with 

 the potash, doubtless Cie Hie Oi. The author promises a more com- 

 plete study of the new alcohol ; the preliminary notice contains much 

 that is obscure and uncertain, — Cornpfes Rendus^ Aug. Wth^ xxxiii, 141. 

 9. On the new metal Donarium, — In the zircon syenite of Brevig in 

 Norway, Bergemann has discovered a mineral which upon examination 

 proved to contain the oxyd of a new metal, Dona rium ; the mineral in ques- 

 tion is a hydrated silicate of donarium [seep. 387], and is represented by 

 the formula Do^ 0^ SiO^-J-'iHO ; it is readily decomposed by chlorohy- 

 dric acid, and after the separation of the silica in the usual manner, am- 

 tnonia precipitates from the solution a hydrated oxyd of donarium as a 

 white voluminous mass, which upon drying becomes gradually yellowish 

 ^nd reddish yellow. The precipitate contains a little iroa from which it 

 is freed by ignition and digestion with chlorohydric acid which dissolves 

 the iron; the oxyd may then be dissolved by long digestion with sul- 

 phuric acid ; from the sulphate the pure hydrate is obtained by precip- 

 itation with ammonia white but becoming yellowish on drying ; it is 

 readily soluble ia acids; in chlorohydric acid without evolution of 

 chlorine. Metallic donarium was obtained from the oxyd by heating 

 with potassium ; the decomposition takes place rapidly with evolution 

 of light, and the metal is separated as a coal-black heavy powder, which 

 under the burnisher assumes a metallic lustre which it retains for seve- 

 ral hours even in moist air. Particles of the metal scattered la the 

 flame of a lamp burn with a reddish light to oxyd. Chlorohydric acid 

 hot or cold has no action on the melal ; nitric acid acts slowly on heat- 

 ing ; nitro-muriatic acid oxydizes it rapidly to red oxyd of which a 

 small portion is dissolved. The anhydrous oxyd obtained by strong ig- 

 nition of the hydrate is of a very deep red color ; its density is 5-57G ; 

 it is soluble only in sulphuric acid after long digestion and subsequent 

 dilution with much water. The solutions of the hydrated oxyd in nitric 

 and sulphuric acids are colorless ; that in hot chlorohydric acid yellow, 

 which color however vanishes upon cooling. Potash, soda, and ammo- 

 ^^a, give with solutions of the oxyd while precipitates which are insol-
