circumstances into acetic and butjric acids. In the course of their investigation? 

 they also prepared and examined the anhydride of propionic acid, propionic ether, 

 propione, propria! and propylene, the three last obtained by the distillation of dry 

 propionate of baryta. 



Slearone. — Heintz has shown that stearone C 35 II 35 i? really produced during 

 the distillation of dry stearate of lime, a fact which bad been disputed by llowney. 



Hlienkamp has examined the action of sulphite of ammonia on nitrobcnzole and 

 nitrotoluole, and has obtained two new acids. 



Rarnmelsbcrg has examined the composition and crystalline forms of the tartrate 

 of ammonia, and the double tartrate of potassa and ammonia. 



Muhlhauser has examined the products of the action of nitric and hydrochloric 

 acids upon the protein compounds, and has found among others a volatile body, 

 chlorazole, which 13 poisonous, burns the skin intensely, possesses a powerful 

 odour, and explodes when strongly heated. 



Fulm'i iiuric or Isocyanuric Acid. — Liebig and Schischkoff have described under 

 these namc3 a new tribasic acid isomeric with cyanuric acid, bnt forming entirely 

 different salts with bases, obtained by the action of alkalic chlorides or iodides upon 

 fulminating mercury. Many of the salts are finely crystallized and explode when 

 heated. 



Ononbie. — Hlasiwetz has examined the body obtained by Reinsch from the root 

 of Ononis spinosa, he finds that it is decomposed by baryta into an acid and a new 

 glucosogenous body, which he calls Onospine, this again by dilute acids is resolved 

 into sugar and a crystallizable substance Ononetine. The decomposition is analogous 

 to that observed in populine. 



Amides. — Rowney has examined a considerable number of the amides of fatty 

 acids. 



Vcratrine — Merck has made some experiments upon pure veratrine and some of 

 its salts, and gives as the formula of the alkaloid C 64 H 52 N 2 ,s . 



Igaaurine.— Desnoix announces the the existence of a third alkaloid in mix vomica 

 in addition to strychnine and bruoine; it remains in the mother liquor after these two 

 have been precipitated by lime. In its properties it is exceedingly similar to brucine. 



Volatile bases. — Greville Williams has published in the Chemical Gazette of No- 

 vember last, the valuable paper read before the meeting of the British Association, 

 on the basic constituents of coal tar, and on chrysene. The communication is not 

 of a nature to allow of an abstract. 



Xapthalive. — Dusart has obtained two new compounds of napthaline, by acting 

 on the protonitrale with potash and lime. He calls them nitrated phthaline ami 

 nitrophthalinic acid. From the former he obtained a new alkaloid Fhthalidine 

 having the formula C 10 H 9 X. 



Nitroglycerine has been examined by De Vrij, who gives the formula C e H a 

 (SO^'-O". He prepares it by gradually adding 100 grms. of glycerine of specific 

 gravity 1"2G2, to 200 cubic centims of monohydrated nitric acid cooled down to 

 14 q F. A3 soon as the two liquids have united to a homogeneous mass, a quan- 

 tity of sulphuric acid equal to that of the nitric acid, is gradually added, keeping 

 the temperature below 32° F. the whole time to avoid an explosion. To psrify it 

 dissolve in ether and wash with water. It explodes at a temperature above 320^ 

 and also when struck. 



Coumaramine. — An artificial alkaloid has been oblained by Frapolli from nitro- 

 ■soumarine. H. C.
