220 ON THE DETRITAL TIN-ORE OF CORNWALL. 
In a part of Treloy which bore no trace of previous operations 
at the surface, it was found that workmen of an earlier period had 
already examined the tin-ground. From amongst the refuse of 
their labours the hereinafter mentioned objects were obtained. 
The Fibula (Fig. 4,)—now im the Museum at Truro—was 
imbedded, amongst previously moved sand and gravel, somewhat 
above the level of the tin-ground which had been already wrought ; 
and was bought of the finder, (a workman on the spot), on the 
day it was found. It is of bronze, inlaid with a narrow oval 
(2 of porcelain) disposed in symmetrical breadths, alternately of 
blue and white.

The pan and cover (fig. 5.) were discovered within a few 
yards of the Fibula; in a part of the tin-ground which bore evident 
proof of having been previously examined, notwithstanding it was 
overlaid by several thin, undisturbed, beds of sand and gravel. 
Rims of perhaps twice the ordinary thickness of the vessel 
and its cover surround the edges of both; and both are thinly 
encrusted with earthy matter of leaden hue; the metal having, 
possibly, become reoxidized,* like the Jew’s-house-tin of Kea and
