A BASIS OF SCIENTIFIC THOUGHT* 

 Lemery in his Cours de Chemie (1675) 

 was the first to separate that branch of sci- 

 ence termed chemistry into organic and in- 

 organic. The latter embraced those bodies 

 found in the mineral world and those pro- 

 duced by means of such substances. Ber- 

 zelius, recognizing that organic bodies con- 

 tained carbon, mainlained that they came 

 about through the influence of a particular 

 force — vis vitalis. Iii 1828, however, Wohler 

 synthetically prepared, from strictly inor- 

 ganic materials in the laboratory, urea, the 

 eventual product of animal metabolism. 

 This discovery was followed by the syn- 

 thesis of numerous other bodies hitherto 

 thought to be possible of preparation only 

 through the mysterious life-force. 



Although the fundamental laws under- 

 lying these divisions of chemistry are the 

 same, yet for pedagogic convenience this 

 classification is adhered to by many ; oth-
