water, and precipitation from it by concentrated alcohol. The 

 aqueous solution of these crystals, treated with hydrochloric acid, 

 deposited small crystals of an organic acid, slightly soluble in cold 

 water. On attentively examining these crystals, M. Heintz ascer- 

 tained that they were identical with succinic acid ; the experiments 

 first performed were merely qualitative, but they were afterwards 

 completed by the elementary analysis, of a small quantity certainly, 

 of these crystals. The form of the crystals was, moreover, that of an 

 oblique rhombic prism ; and M. Heintz found, by very exact ad- 

 measurement, that the angles of these crystals were equal to those 

 of pure succinic acid. These experiments sufficiently demonstrate 

 the interesting fact, announced by the author, relative to the exist- 

 ence of succinic acid in the animal ceconomy. — Journ. de Pharm.

ON A NEW COMPOUND OF SULPHUR, CHLORINE AND OXYGEN. 

 BY M. MILLON. 



To prepare this, fill a bottle of the capacity of 4 to 5 litres with 

 moist chlorine, and introduce at first 20 to 30 grms. of chloride of 

 sulphur saturated with chlorine, and then 2 or 3 grms. of water ; agi- 

 tate the mixture, and surround the bottle with a freezing mixture of ice 

 and common salt during 4 or 5 hours. A great disengagement of 

 hydrochloric acid occurs ; the bottle is to be again filled with moist 

 chlorine and replaced in the freezing mixture, and this is to be re- 

 peated till the chloride of sulphur becomes a crystalline mass. These 

 crystals are destroyed with violent action by water, alcohol or diluted 

 acids. But if, after freeing them from the chloride of sulphur 

 which renders them impure, they are allowed to fall into a very dry 

 tube, the open end of which is closed by the lamp, these crystrals 

 in two or three months soften, and in eight months become an ex- 

 tremely fluid liquid ; it is an isomeric transformation which becomes 

 evident, not only by the change of its physical qualities, but also by 

 the alteration of its chemical properties. Thus the liquid is no longer, 

 as when in the crystallized state, decomposed by water, with violence, 

 alcohol or weaker acids ; on the contrary, when poured into water it 

 is quietly deposited at the bottom of the vessel in the form of an oil, 

 which eventually changes completely into sulphuric and sulphurous 

 acids. This transformation is entirely in agreement with its ana- 

 lysis, which leads to the composition of sulphur, chlorine and oxygen,

The analysis is performed with the liquid modification ; a weighed 



vessel is filled with it, and is broken in a bottle containing nitrous 



nitric acid. The reaction which occurs is moderated by cooling the 



bottle ; the sulphur is subsequently estimated in the state of sulphate
