gone considerable chemical change. They differ very markedly 
in appearance from the smaller flints in the upper strata. No 
implements, “ eoliths,” or fossil bones have been met with in 
this bed. 
THE GRAVEL FLOOR. 
The floor of the gravel, where the remains of Eoanthropus 
were discovered, has been carefully exposed, and many irregu- 
larities and depressions have been found to exist. In some of 
these depressions small patches of the dark overlying bed 
remained, and new specimens were discovered. The finds 
made this year are few but important, and include the nasal 
bones, and a canine tooth of Eoanthropus discovered by Father 
P. Teilhard de Chardin ; also a fragment of a molar of Stcgodon 
and another of Rhinoceros ; an incisor and broken ramus of 
Beaver ( Castor fiber) ; a worked flint from the dark bed ; 
and a palaeolithic implement from the debris in the pit. It 
will be noted that the remains are those of a land fauna only. 
The further occurrence of bedded flint-bearing gravels in the 
vicinity of the pit is noted. The authors’ former conclusions, as 
to the Pliocene forms having been derived, are maintained. 
CRANIUM OF EOANTHROPUS. 
A further study of the cranium of Eoanthropus shows that 
the occipital and right parietal bones need slight readjustment 
in the reconstruction, but the result does not alter essentially 
any of the conclusions already published. The nasal bones, 
now' described, are typically human, but relatively small 
and broad, resembling those of some of the existing Melanesian 
and African races. The right lower canine tooth may be 
regarded as belonging to the imperfect mandibular ramus 
already described. It is relatively large and stout, and, 
like the molar teeth, it has been much worn by mastication. 
The worn surface on the inner aspect extends down to the 
gum, and proves that the upper and lower canines completely 
interlocked, as in apes. In shape, the canine resembles the 
milk-canine of man and that of the apes more closely than it 
agrees with the permanent canine of any known ape. In 
accordance with a well-known palaeontological law, it therefore 
approaches the canine of the hypothetical Tertiary An- 
thropoids more nearly than any corresponding tooth hitherto 
found. 
PROF. ELLIOT SMITH. 
In a note appended to the paper, Professor Elliot Smith 
points out that the presence of the anterior extremity of the 
sagittal suture, which hitherto had escaped attention, had en- 
abled him to identify a ridge upon the cranial aspect of the 
frontal bone as the metopic crest, and thus to determine
