Dr. Seebeck, of Jena, has obtained indications of an Magnesia and

Mr. Trommsdorff has prepared an artificial succinic acid. Artificial suc- 



For this purpose he employs the saccholactic acid of cimc acu ** 



Scheele, which he introduces into a retort and subjects to 



dry distillation. The products of this distillation deserve 



farther inquiry. 



He has likewise examined the sulphuretted alcohol of Sulphuretted 



Lampadius, and found in it several new properties. As it ^ lcoho1 « f

in large quantity; one part dissolving eight of phosphorus 



and still remaining liquid. This solution of phosphorus 



readily takes fire in the open air. In close vessels it may be 



decomposed by heat. The sulphuretted alcohol first passes 



over, though not quite free from phosphorus. 



Fecula dissolved in boiling water undergoes a remarkable Fecula 

 change, when evaporated over a moderate fire. It becomes fc^f C y 

 a semitransparent horny mass perfectly insoluble in hot 

 water. Wetted, and kept five months in a pretty warm 

 place, Mr. Trommsdorff could not find it exhibit any signs 

 of fermentation. 



Mr. Trommsdorff repeated Mr. Cadet's experiments on Camphorated 

 the solution of camphor in distilled water*. He found f soc i a , 

 them accurate ; but he also found, that the camphorated 

 water is rendered turbid by pure soda, and consequently 

 will not serve as a test to distinguish this from potash. Mr. 

 Vogel has made some trials, that confirm this: but soda 

 combined with a certain portion of carbonic acid does not 

 precipitate the camphor.
