The society take notice, and their remark is probably 

 applicable to the processes made use of in this country, that 

 great savings of fuel, and other advantages have been de- 

 rived from scientific improvements in the furnaces made 

 use of in many of the arts ; but that in the fabrications 

 which form the subject of the present question, no sucb 

 improvement has taken place ; they therefore ofer the be- 

 fore mentioned prize^ to those who shall establish works 

 in France in which these articles shall be made with the 

 least expence of fuel

 Ko;fe.bcan3. district where they are not at present Used, 60Q francs*
