A. T. METCALFE ON VERTEBRATE REMAINS 
found in it a large number of 
bone fragments, including seve- 
ral portions of jawbones of rep- 
tiles, with teeth in line. In 
the autumn of 1882 I myself 
visited High Peake Hill, and 
succeeded in finding in the 
talus numerous fragments of 
fossilized bone, including one 
flat one (probably dermal), 
3 inches by 2 in size. In this 
specimen the bone structure is 
remarkably well preserved and 
distinctly visible to the naked 
eye. I was also particularly 
struck with the presence of 
numerous isolated small white 
fragments of irregular shape, 
both thick and thin, in the 
blocks of sandstone, most of 
them no larger than a florin, 
and many as small as a six- 
pence. Fragments of a similar 
character have been examined. 
under the microscope, by Mr. 
Carter, whose statement is as 
follows :— 
‘‘ Where the consistence is 
firm the bone structure is visible 
throughout, although there may 
be no form for identification. 
In other specimens which have 
become soft, chalk-like, or pul- 
verulent when dry, the presence 
alone of little thin plates of 
translucent material (somewhat 
like mica in appearance, but 
calcareous in composition), dis- 
persed irregularly throughout 
the mass, preserves the bone 
structure, and that so unmis- 
takably, that they can be thus 
satisfactorily identified, even 
without form. These fragments 
are occasionally more or less 
replaced by red clay, and also 
more or less charged with erys- 
talline grains of quartz, a cir- 
cumstance which appears to 
arise from a metamorphic 
transposition of the surround-
