158 New Talents. [Au«. 



VIII. Hjelms and Ekeberg. 



These two Swedish chemists, both possessed of considerable 

 celebrity, died during the course of the last year. I shall take a 

 future opportunity to make the reader acquainted with the chemical 

 works which they published, and the improvements they introduced 

 into the science. Peter Jacob Hjelms was born on the 2d Octo- 

 ber, 1746' ; and died on the 7th October, 1813. He first obtained 

 molybdenum in the metallic state. Andrew Gustavus Ekeberg was 

 born in 176'7 ; and died the 11th February, 1813. His experi- 

 ments on yttria and tantalum are well known. 



IX. Veins of Tin Ore discovered in France. 



Three quartz veins containing tin ore have been recently disco- 

 vered in the commune of Piriac, in Britanny, near the sea shore, 

 running through a granite mountain. The veins were examined by 

 d'Aubuisson, and the ore was assayed by the Council of Mines at 

 Paris, and found as rich as tin ore usually is. No description of 

 the size or richness of these veins is given. Hence we cannot 

 guess whether they be worth working ; but from their being near to 

 Cornwall, situated in the same kind of country, and running in the 

 same direction with the Cornish tin veins, hopes may be entertained 

 that a depot of tin ore may be hereafter discovered in Britanny. 

 See Ann. de Chun. Ixxxviii. 16'2. 



X. Valuable Chemical Library for Sale. 



The Professor of Chemistry at St. Petersburgh, Dr. Scherer, has 

 a most valuable chemical library, which he is desirous of selling. A 

 complete catalogue systematically arranged is printed. The number 

 of volumes is G'UoO, the greater part German, but also in other lan- 

 guages, as English, French, Italian, Spanish, Russ, Swedish, &c.
