THE GEOLOGIST. 



"really 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 imiDlements 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 implem.ents and the haches gmdoues ou celtiques. . . . 

 Beside the chipped implements, round pebbles also occurred, which are 

 considered by Dr. JSToulet 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." 



Swalecliffe (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 of Elephas primigenius. 



JPeasemarsh, Surrey. — One implement found by Mr. E. 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 apparently 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. 

 Grod\A in- Austen, in Quart. Journ. Geol. Soc. 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. 



Ilorton Kirhy, Kent. — An implement of the round-pointed form was 

 found (November, 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 ^iven, and Mill 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 Reculvers — 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 Arraugement of the Fishes of the Devonian Epoch. By 

 Professor Huxle3^ 



A most valuable contribution this to palteontological science. From the 

 endeavour to determine the systematic position ofGlyptolfemus mfiv&t de- 

 scvil)ing it in Dr. Anderson's "Dura Den," Professor Huxley has been led 

 to Iho nM'oiisidri nli.m of the chissitication of the fishes of the Devonian 

 oi)Oi'li, anil (>\ .Mihuilly to make important modifications of the received 

 arrangomont of I he Ganoidei. We give a brief summary of the Professor's 

 views. ' , 



Glyptolcrmus is regarded as a tolerably typical member of a large and 

 ^^oll-(.lollucd family of Ganoids which abounded in the Devonian epoch, 

 but M liosc members have been less and less numerous in more modern
