THE GEOLOGIST. 
" real!}'' the case that this is in part polished, and that this polish is 
not due to the natural fracture, it is certainly a singular fact in connection 
with the implements of the Drift period, which have hitherto always been 
not ground. Dr. jSToulet, however, has paid some attention to this class of 
antiquities, as he draws a distinction, on account of their rude workman- 
ship, between these implements and the haches gauloises ou celtiques 
Beside the chipped implements, round pebbles also occurred, which are 
considered by Dr, Koulet to have been used as hammers ; and, though 
the account he gives of the whole discovery is not to my mind quite con- 
clusive, it appears to be a proper case for further inquiry," 
Sicaleclijfe (I, of Sheppey). — At the end of Stud Hill Cliffs, near the 
Swalecliffe Coast-guard Station, Mr, Evans picked up a flint-implement of 
the oval-pointed form, stained by ochreous colours, from having lain in the 
gravel ; and in the Drift capping the highest point of the cliff, close to the 
farm-house at Stud Hill, a portion of tooth oi Eleplias primigemus. 
Peasemarsh, Surrey. — One implement found by Mr. R. Whitbourn. 
r.S.A., of Godalming, twenty-five years ago, in a gravel-pit. " It was 
embedded in gravel, in a layer of sand about 4 or 5 feet from the surface, 
in apparentl}' undisturbed ground." Mr. Whitbourne adds, " I have 
heard of remains of large animals having been discovered in the same 
beds, but not in very close proximity to the spot where it was found." 
The gravel-beds of this district have been examined and described by Mr. 
Godwin-Austen, in Quart. Journ. Geol. Soe. vol. vii. p. 278, in which 
communication he states that remains of Elephas primigenius are fre- 
quently found in this g^-avel, and that at Peasemarsh there are traces of 
an old land-surface, with branches of trees and the bones of these animals 
uninjured and lying together. 
Horton Kirhy, Kent. — An implement of the round-pointed form was 
found (jVovember, 1861) on the surface of the ground at the top of the 
hill, on the east side of the Eiver Darent, about a mile E.S.E, of Horton 
Kirby, by Mr, Whitaker, of the Geological Survey. 
The remainder of this valuable paper is chiefly devoted to extended 
illustrations of Mr. Evans's original classification of these implements 
into, 1, flakes ; 2, weapons with an acute or rounded point ; 3, oval or 
almond-shaped implements, with a cutting edge all round. A plate of 
twenty examples, drawn to a scale of one-half linear, is given, and w ill be 
very useful to students and inquirers in conveying a correct idea of the 
sorts and kinds of these objects. Plates of the flint-implements from the 
Valley of the Ouse, Swalecliffe, and Eeculvers — one of the latter formed 
from a large Tertiary flint-pebble — are also given. 
Memoir of Geological Survey. Decade X. Preliminary Essay upon the 
Systematic Arrangement of the Fishes of the Devonian Epoch. By 
Professor Huxley. 
A most valuable contribution this to palseontological science. From the 
endeavour to determine the systematic position of GlyptolcFmus 'm^r&i de- 
scribing it in Dr. Anderson's " Dura Den," Professor Haxley has been led 
to the reconsideration of the classification of the fishes of the Devonian 
epoch, and eventually to make important modifications of the received 
arrangement of the Ganoidei. We give a brief summary of the Professor's 
views. 
GlyptolcBmus is regarded as a tolerably typical member of a large and 
well-defined family of Ganoids w hich abounded in the Devonian epoch, 
but whose members have been less and less numerous in more modern
