IN THE TRIAS OF DEVONSHIRE. 259 
ing material in which the carbonate of lime of the fossilized bone 
has been removed by aqueous solution ‘previous to the deposit of the 
foreign ingredients.” 
On careful search I also found in the harder beds of the sand- 
stones, at numerous spots near Budleigh Salterton and Otterton 
Point, small white (and occasionally red) fragments similar in 
outward appearance to those in the talus at High Peake Hill, but, 
of course, from lower horizons. Mr. Carter has carefully examined 
such fragments, and informs me that he is clearly of opinion that 
they also are, or represent, bone tragments. Mr. Carter thus 
observes :—‘“‘ Concentric lines may be seen in them precisely 
similar to those in the fragments from the talus at High Peake 
Hill, but no bone structure or form is identifiable, while the 
white calcareous material, of which they are chiefly composed, is 
hardened, and the whole more or less reddened by the presence 
of red clay, and altered by that of crystalline grains of quartz 
similar to those found in the specimens from High Peake Hill, 
in which the bone-structure is distinctly visible.” It was in the 
hard conglomeratic beds of one of these lower horizons close to 
Budleigh Salterton that Mr. Whitaker, F.G.8., of Her Majesty’s 
Geological Survey, in 1868, found the specimen to which Prof. 
Huxley afterwards gave the name of “ Hyperodapedon” (Q.J.G.8. 
vol. xxv. pp. 146, 156); and I am further informed by Mr. Carter, 
who has seen the specimen in the Museum of the School of Mines, 
at Jermyn Street, that but for form there is here also, probably, no 
bone structure for identification. 
In a small quarry in the sandstones, close to Shortwood Hill (on 
the Tidwell Estate), about four miles west from High Peake Hill, 
are similar white fragments, chalky and structureless in character 
generally, but still containing, as Mr. Carter has proved, the plates 
of bone structure above mentioned, together with a large quantity 
of concretionary carbonate of lime in the upper strata, in which, of 
course, there is no organic structure whatever. 
Mr. Carter has also deposited, with the remains boPone mentioned, 
earefully prepared specimens and sections of the bone fragments 
illustrating the foregoing observations. ‘There can be no doubt that 
the great blocks, from the surface of which he chiefly obtained the 
remains, do contain, interiorly, many more of the same kind, which 
are soon washed out by exposure to the weather and the waves, 
being, as was before stated, of a soft or chalky nature when moist. 
Unless, therefore, the blocks are broken open, the chance of finding 
in them further traces of such organic remains becomes daily less; 
although, of course, a rich find might at any time follow a fall from 
the same bed of the cliff. 
I carefully examined the length of the Triassic rocks exposed on 
the coast from the Upper Marls of Seaton to the breccia in the neigh- 
bourhood of Torquay (30 miles) ; but only in the Upper Sandstones 
were these peculiar bone fragments visible. The Upper Sandstones, 
as exposed on the coast between Budleigh Salterton and High Peake 
Hill, are remarkable for the presence of curious, irregular, branch-
