Oj-l-NOg. The action of hyponitric acid upon metallic oxyds yields a 

 nitrate and nitrous acid. Tlie action of hyponitric acid upon sulphuric 

 acid has been studied by Weltzien. In repeating the experiments of this 

 chemist Miiller obtained the same crystalline compound and the same 

 formula, SOaHO-t-SOgNO;.— ^nn. der Chemie und Pharm., xlvi. 1. 



8. On the sulphids of the alcohol radicals.— CAmvs and Ferrein have 



obtained two oxysulphids of glycerin to which they give the names of 



glycerin-moDOsulphydrate and glycerin-disulphydrate. The compounds 



in question are obtained by the action of raonochlorbydrin ^^s j. ^4 



and ^eJJs I O2 upon an alcoholic solution of sulphid of potassium. 



Both are oily liquids, having a faint odor of mercaptan ; they are soluble 



in water and decomposed by distillation. The first compound has 



the formula ^^^^ I O^Sg ; the second is represented by « j^^ | OgS^. 



Oxjd of mercury acts upon the disulphur compound as upon mercaptan 



and forms a white salt having the formula ^^^^5 | Q^S^.—Ann. der

9- On certain Ammonia-ruthenium Bases.— Clkvb has discovered and 



- ;bed two conjugate bases containing ammonia and ruthenium and 



eh he gives respectively the names of ruthenamiak and rulfien- 



"^•. The author considers these bodies as containing the conjugate 



'^^ NB3H,,, and 2NH7Ru, which unite with an equivalent of oxygen 



ine, etc^The salts of ruthenamiak alone are described m detail ; the 



c'.i ,rid 2NH3RUCI is easily formed by boiling a solution of chlor-ru- 



t^enate of ammonium RuCirNH^Cl with ammonia, evaporating the 



orange yellow solution to dryness, and washing the dry mass to remove 



ssl-ammoniac. The chlorid is a beautiful yellow crystalline salt, havmg 



tj^e formula 2Nh7:RuC1+3HO. The sulphate of this base contains 



• fo^r, the nitrate two, and the carbonate five equivalents of water. The 



Jreehase exists only in solution; it has a strong alkaline reaction ana its 



^o'"tion can be tasted only with the utmost caution, as it produces a very 



P'-^'^f-d affection of the tongue. It precipitates many metalhc oxyds 



';Ppears to be still more caustic than the oxyd of ruthenbiamiak, and pro-
