oxidized to carbon dioxide and water, the former being

 chloride. The method now in use differs from that of 

 Liebig in only a few particulars, the principal of which 

 is that gas has superseded charcoal.

 cyanates, which were also being studied by Wohler.

 and many papers were published under their joint names. 

 Liebig's researches were published in Poggendorff's

 Handworterbuch der reinen und angeivandten Chemie ; 

 and Jahresbericht der Chemie : in all he published three
