26 New Metltod of separating 



design was the side of a large altar ; the pediment presented 

 a medallion of the deceased : on the dodo were three figures 

 in |?as relief, — Painting wrote his name. Sculpture supported 

 her arm, and Architecture looked on with a mournful coun- 

 tenance. I have introduced this anecdote to inform Eng- 

 lishmen of particular virtues and talents in an enemy's 

 country which otherwise might not be so generally known, 

 and to let Frenchmen see that we can acknowledge what- 

 ever is praiseworthy in them with as much zeal as they 

 would themselves. 



I have only to add my earnest wishes as an Englishman 

 and a real lover of my country, that we may in future cul- 

 tivate the arts of design with as much fervour, and labour 

 as indefatigably to bring them to perfection, as the French 

 haye done, by those means only which are just and ho- 

 nourable. 



I have the honour to be, &c. 



IV. New Method of separating Tin and Copper from BelU 

 Metal. By C. Anfrye, Assay Master of the Mint*. 



JT rance, deprived by war of many of the products which 

 commerce afforded her in ordinary times from foreign coun- 

 tries, was not very long ago almost totally destitute of copr 

 per. Pressed by the distress which the scarcity of this metal 

 occasioned in the casting of artillery and other articles for the 

 common purposes of life, all the enlightened chemists were 

 called together, and from their knowledge that assistance 

 was demanded which the science they professed could af- 

 ford towards warding off the impending danger. These 

 expectations were not disappointed : its hopes were realized 

 even beyond the point to wnich they were directed. In the 

 year 1792 all the French chemists were busied in finding 

 out an easy and expeditious method of separating the copper 

 from the other metal of which their church bells were ma- 

 nufactured ; the only source from which copper could be 

 obtained. They were successful in their attempts, and the

 by Dr. Bourlaye to professor Tromsdorflf, and inserted, by permission,

Dr. Bourlaye remarks, that by this ingenious invention the republic of 

 France has saved upward of seven millions of pounds of copper and one 

 milfion of pounds of tin, which were thrown away as an useless refuse 

 of the process formerly adhered to for separating copper from bell-metal.
