Arr. XXX.— Biography of Berzelius ; by Prof. H. Rose, 
of Berlin. 
(Continued from p. 186.) 
Somerme after the appearance of the mineral system, Ber- 
zelius published his work ‘‘Ueber die Anwendung des Lithrohrs 
in der Chemie und Mineralogie.” In Fahlun, under the guid- 
ance of his older friend Gahn, a pupil of Torbern Bergmann, he 
ad acquired uncommon dexterity in the use of the blowpipe ; 
and he had thus enriched this special part of chemistry with a 
humber of original investigations, and brought it to a high de- 
gree of perfection. In the above-mentioned work he makes 
known everything connected with the subject, both what he 
had learned from Gahn and what he had himself discovered. 
Rarely has a work been welcomed by chemists like this; in- 
deed, so immediate a recognition of the practical value of a work 
1s seldom possible. It was at once translated into most European 
languages; and in some, especially the German, it passed through 
Several editions. Everywhere it met with merited appreciation ; 
and Mr. Children alone, the editor of the English edition, allowed 
himself to add remarks as superfluous as they were ill-natured. 
Besides the behavior before’ the blowpipe of the most import- 
ant chemical compounds, all metallic oxyds, acids, and their 
salts, sulphurets, &c., Berzelius described the reaction of all 
more readily placed at his disposal, as he required only very small 
quantities for these experiments. He entered upon this investi-
