dissolves this impure arsenious acid, and yields a solution from 

 which water throws down a white precipitate* sulphuretted hy- 

 drogen an orange one of sulphuret of antimony, and then a yellow 

 one of sulphuret of arsenic. Nitric acid, when heated, dissolves the 

 mixture, leaving a residue of oxide of antimony containing arsenic 

 acid, which is readily dissolved by hydrochloric acid and by tartaric 

 acid; and it forms solutions with these acids, which possess all the 

 reactions of oxide of antimony. M. Wiggers found oxide of anti- 

 mony only in the vitreous arsenious acid from Andreasberg in the 

 Hartz. — Ibid. 



DISCOVERY OF A NEW METAL. 



" In Part Seventh of my Journal, which you will receive next week, 

 you will find a notice of the discovery of a new metal ; it has been 

 named Didym ; it always accompanies Lanthanium, from which un- 

 fortunately it has not yet been separated. All the researches on 

 Lanthanium, as well as those on Cerium, are erroneous." — Extract 

 of a letter from Prof. Poggendorff to W. Francis.
