of the fame dru&ure, and part of the above-defcribed 
lump, but is much richer in quality. It was fent 
me on the 12th of Augud lad by Mr. Henry 
Rofewarne, of Truro, a gentleman well verfed in 
the knowledge and fufion of metals. Bcfides all 
the appearances of native tin taken notice of, in the 
former fpecimen, here, in this N° 2. we fee the 
malleable tin, in color equal to the fined; tin of the 
furnace, more liberally and didindtly difperfed. The 
metal is not only found in granules, but in a foliaceous

tin. 
The third fpecimen is as follows. On the 17th of

palled unnoticed. Within the crud, the metal was 
not in granules, as in the fird fpecimen, nor thm as 
a leaf, as in the fecond ; but much more abundant,
