From 1822 to 1848 Berzelius wrote a series of Annual 

 Reports on the Progress of Physical Science. The German 

 translations by Gmelin and by Wohler are familiar under the 

 name of Berzelius's Jahresberichte, and are quoted in several 

 places in the text. Another important publication is his Text- 

 book of Chemistry, First Edition, 3 Vols. (in Swedish), 1808- 

 1818 ; Fifth Edition, 5 Vols. (in German), 1843-18/18 ; quoted on 

 P- 398
