recognizing with Prestwich, and working out the distinction between the high 
level and low level drifts of the Pleistocene era, with pertinent observations on 
lacustrine and river action. Mr. Symonds strongly appealed to his fellow 
members to aid him with their individual observations, by noting particularly 
the organic contents of the drifts ; a clue might thereby be obtained that 
would elucidate many of the pleistocene phenomena. 
Thereon ensued a discussion, sustained in a lively and erudite manner, by 
Messrs. Moore and Woodward, the latter contributing a just and discriminating 
account of the palseontological differences between high level and low level 
" mammalia," with geological remarks on the habits of the tropical Bison and 
the larger Pachyderms, such as Elephas antiquus and E. pnmigenhis, glancing 
at their aptitude for enduring the rigor of the glacial epoch. 
Another paper was communicated by Mr. Prederick Smithe on the Upper 
Lias of Churchdown Hill, a similar formation to Dumbleton, the writer, after 
giving a brief resume of the divisions and sub-divisions of the Lias and the 
synonyms of the subordinate zones as used by the chief European authors, 
restricted his attention to the "^Ammonites communis Zone" of the Upper 
Lias, which reposes on the marlstone, and treated this zone in its development 
at Churchdown — first lithologically, then palseontologically. 
As to the included beds, the A communis Zone comprises (1), on top the 
Laminated Shales ; (2), the Pish Beds within them ; (3), the Leptsena Bed 
lymg beneath the " Alga-bed ;" (4), the Marlstone upper beds, embracing a 
course of siliceous nodules. The author had exhumed remains of Teleosaurus, 
and Pterodacti/tus, Colma, a not uncommon Lias crustacean, Tachycormus, 
Tetragonalepis concent ricus, Lepidolepis ovalis and dapedius ; also, Belemno- 
sepia, Ammonites, and such molluscan forms as Ostraa, Nucula, Area, Modiola, 
Monotis and JPosidonomya. 
Rostellaria bein^ nearly the only gasteropod in the catalogue. In short, 
for a locality considered so poor in comparison with the Somersetshire deposits, 
not a bad harvest. 
The president, at the close of a most enjoyable day, admitted to be one of 
the most delightful meets of the season, invited the members to attend, on the 
17th of September, at Worcester, when Sir Charles Hastings, the Bishop of 
the diocese, and M. Chaillu, the African traveller, are expected.

Stone Weapon in a Possil Deer's Skull. — Sir, — In the notice you took 
of my pamphlet in the " Geologist" of June last, entitled " Remarks on the 
Plint Instruments found at Amiens and Abbeville in connection with the 
Glacial Theory," you consider that it would be highly desirable for me to elu- 
cidate one remarkable statement made by a more particular statement of the 
facts. The ' statement you allude to I consider to be that in italics : " I can 
prove that the Irish Elk was contemporaneous with man, having seen a stone 
hammer sticking in the skull of one, and also the heads of others which had 
been perforated by the same kind of weapon." 
I can now give you full satisfaction on that subject, having now in my pos- 
session the identical stone hammer, or rather stone axe, or celt, which was
