This Journal is devoted to Scientific and Applied Chemistry, and also embraces whatever 
tends to elucidate new discoveries in Mineralogy, Metallurgy, Mining, Mechanics, Eledtricity, 
and the collateral branches of Physical Science. It also contains an encyclopaedic list of 
chemical papers published abroad during the previous week, with abstracts of all susceptible 
of advantageous abridgment, thus making the two half-yearly volumes, with their copious 
indices, equivalent to an English edition of the “ Jahresberichte.”
