valleys; and Dr. Falconer remarked that at the present time the con- 
sideration of the general inferences to which these cases lead may 
probably be of some use. After discussing at some length the cases 
in which Human and other Mammalian bones had been stated to 
occur in the Valley of the Nile, Dr. Falconer described the general 
features of the Alluvial deposits of the Ganges and Jumna, stating 
what organic remains had been found in them. In a comparison of 
the two regions, Dr. Falconer observed that there is a striking ana- 
logy between the Alluvial deposits occurring along the banks of the 
Nile on the one hand, and the Ganges and Jumna on the other, the 
most obvious being the great abundance, in both cases, of argillaceo- 
calcareous concretions, forming an impure kind of travertine, and in 
the lowermost beds horizontal deposits of the same material; but 
that in its poverty of vertebrate remains the former, so far as it has 
been explored, is a remarkable contrast to the latter. Dr. Falconer 
then reverted to an opinion expressed by Sir Proby Cautley and 
himself many years ago, namely, that the Colossochelys Atlas may 
have lived down to an early epoch of the Human Period, and become 
extinct since; and he concluded with some general observations on 
the question of the antiquity of the human race, suggested by more 
recent discoveries. 
If. April 5, 1865; Sir R. I. Murchison, Vice-President, in the 
chair.—The following communications were read :—1. ‘ On the Ter- 
tiary Deposits in the Colony of Victoria, Australia.’ By the Rey. 
J. E. T. Woods, F.L.S., F.G.S.—The author first referred to his 
former paper on the Australian Tertiary strata, and then described 
the beds of Muddy Creek, near Hamilton, mentioning the principal 
fossils occurring therein, especially a species of T’rigonia: he also 
stated that the same formation occurs at Harrow, on the River 
Glenelg, about sixty miles to the north-east, as well as in Tasmania. 
In discussing the age of these beds he adopted Professor M‘Coy’s 
views, that they are of Lower Miocene date; but he considered the 
Mount Gambier Limestone to be more recent, probably older Plio- 
cene, and the Murray River deposits as possibly holding an interme- 
diate position: the latter he therefore considered to represent the 
Upper and Middle Miocene of Europe. Older than all these are 
certain strata occurring at Port Phillip and elsewhere, which the 
author referred to the Upper Eocene period. In conclusion, Mr. 
Woods gave a sketch of the salient features of the Bryozoal faunze 
of the deposits occurring at Hamilton and Mount Gambier, chiefly 
for the purpose of showing that the latter is much the more modern 
of the two, 
In a note, Dr. Duncan enumerated the species of Corals which had 
been sent him by Mr. Woods ; but he stated that, although they had 
avery recent aspect, no exact geological date could safely be assigned 
to them. 
2. ‘On the Chalk of the Isle of Thanet.’ By W. Whitaker, Esq., 
B.A., F.G.S., of the Geological Survey of Great Britain.—In this 
district a bed of comparatively flintless Chalk overlies one with 
many flints. The higher division, or Margate Chalk, contains but few
