By the action of chlorine on sulphobeuzole a neutral compound 



is obtained, bichloride of sulphobenzole, cisR^CI SO^i^^^^^

chlorinated sulphobenzole, ci2jj4QigQ2 \, a body crystallizing 

 from alcohol in microscopic acicular crystals. 



Gericke prepared the lead, copper, barium, zinc, calcium, and 

 sodium salts of sulphophenylic acid, which is obtained as a col- 

 lateral product in the preparation of sulphobenzole. They are all 

 soluble and crystalline. By acting upon the sulphophenylate of 

 silver with iodide of sethyle, he obtained sulphophenylic aether. 



By the action of nascent hydrogen on bisulphide of carbon, 

 M. Girard* has obtained a new compound. To pure bisulphide 

 of carbon a considerable quantity of granulated zinc is added, 

 and then dilute hydrochloric acid. An action commences im- 

 mediately, which must not be allowed to become too violent ; 

 sulphuretted hydrogen and the vapour of bisulphide of carbon 

 are given off. At the expiration of a week the action is com- 

 plete ; the mixture is distilled, and there is left a milky residue 

 on which swims an oil not volatile at 100 degrees. By treating 

 this oil with aether, a substance crystallizing in magnificent 

 needles is obtained. It gave on analysis numbers corresponding 

 to the formula CHS, and its formation may be thus expressed : — 



nCS2-h2?iH=MCHS + 2nHS. 



This, substance is soluble in many media ; it volatilizes at 150° C. 

 It is neutral. The strong mineral alkalies exercise no character- 

 istic action, ammonia is inert. It is decomposed by strong nitric 

 and sulphuric acids. It forms with nitrate of silver a compound 

 crystallizing in large white crystals ; and with bichloride of pla- 

 tinum and chloride of mercury it also forms compounds. 



For the preparation of the chlorides and bromides of the 

 organic acids, M. Bechampf avails himself of the action of the 

 terchloride, or terbromide of phosphorus, on the corresponding 

 monohydrated acid. The terchloride acts upon a monohydrated 

 acid as it would upon a mixture of anhydrous acid and water, 

 and ujjon the a;ther of the acid in a corresponding manner. 

 If li is the oxygenized radical of a monobasic anhydrous acid,
