Dr. Pearson's Observations 
4°4 
the parts not covered with oxide or dirt, were yellow, like ra- 
ther pale brass ; the scabbard was somewhat less yellow ; and 
the spear-head and sauce-pan were of a pale yellowish-brown 
colour. The celt. No. 3. was covered entirely with black 
oxide and other extraneous matter. 
(6) A small part of the surface of each of the articles being 
filed or rubbed to remove the exterior matter, the colours of 
all of them were what I would call different shades of pale 
copper colour; not very different from gun metal and prince's 
metal, but not at all like brass. They all took a fine polish, 
which, when first produced, was pale coloured and whitish ; 
but, by exposure to the air, it became deeper coloured and 
tarnished. On examination of the polished surfaces with a 
lens, the metallic matter appeared perfectly homogeneous, and 
of a close texture. 
The articles being cut through with a chizzel, the same dif- 
ferences among the cut surfaces appeared, as among the po- 
lished surfaces just described. On fracturing the metallic 
bodies, the visible interior structure or texture did not appear 
similar in colour and grain. 
The spear-bead was open grained, almost as copper ; and 
porous, as if made of bad metal, but of a blackish-brown, or 
dark grey colour. 
The sauce-pan was also open grained or porous, although 
less so than the spear-head. The colour of the grain, like that 
of the spear, was dark brown or grey. 
The lituus and the scabbard were close grained ; lighter co- 
loured than the former, but grey. 
The celts were all open grained, but much less so than the 
pan and spear-head ; and differed from them in being brown.
