This is diftinguifhed from the other metals 

 by its following characters and qualities. 



a. Of a white colour, which verges more to 

 the blue than that of filver. 



b. It is the moft fufible of all metals •, and, 



c . The lead ductile •, that is, it cannot be 

 extended or hammered out fo much as the 

 others. 



d. In breaking or bending it makes a crack- 

 ling noife. 



e. It has a fmell particular to itfelf, and which 

 cannot be defcribed. 



f t In the fire it is eafily calcined to white 

 ames, which are twenty- five per cent, hea- 

 vier than the metal itfelf. During this 

 operation, the phlogifton is feen to burn 

 off in form of fmall fparkles among the 

 allies, or calx. 



g. This calx is very refractory, but may, 

 however, with a very ftrong degree of 

 heat, be brought to a glafs of the colour 

 of hard refin. But this calx is eafily mixed 

 in glafs compofitions, and makes with them 

 the white enamel. 



h. It unites with all metals and femi-metals ; 

 but renders moft of them very brittle, ex- 

 cept lead, bifmuth, and zink. 



f. It amalgamates eafily with quickfilver. 



/;., It dhTolves in aqua regia, the fpirit of fea- 

 falt, and the vitriolic acid j but it is only 



corroded
