40 EROCEEDIKGS OF THE GEOLOGICAL SOCIEXT. [DeC. 6, 



implement, very well finished, and of the ovoid type, colour, and aspect 

 common to those fonnd at Waren's Pit, St. AchenL It is 3| inches 

 long by 1| broad,finely pointed, and white, with a porcellaneous lustre. 

 It shows no wear. I could find no other, nor any organic remains. 

 The elevation of the pit, according to the levels obligingly furnished 

 me by General Sir Henry James, is about 200 feet above the river, 

 which is here 115 feet above the sea-level. 



Between this pit and the river are two other well-marked broad 

 gravel terraces, in the lower one of which mammalian remains have 

 been found abundantly in other parts of the Avon valley. The section 

 is as in fig. 1. 



The level of the lower terrace is from 30 to 70 feet above the 

 river, of the second from 150 to 180 feet, and of the third or upper 

 terrace about 200 to 250 feet. 



This discovery is in keeping with that of the flint implements in 

 the gravel of the cemetery at Salisbury, which Mr, Evans estimates 

 at 110 feet above the river, and with those of Southampton Common, 

 which Mr. Codrington places at an elevation of 86 and 1 50 feet above 

 the river at Southampton. The diflference, with the first-named of 

 these spots especially, is that there the flint implements are of the 

 rudest pattern and make, whereas at Downton the implement is of 

 the neatest and best-finished construction, although the gravel is one 

 of the oldest in the district, being prior to the excavation of the valley 

 to the greater depth of some 200 feet, to the spread of the lower 

 gravels, and apparently to the great development of the Postglacial 

 mammalia. 



Discussion. 



Mr. Codrington stated that, according to the Ordnance Survey, 

 the level of the pit at Cams Wood was not more than 100 feet 

 above the sea, so that it was at about the same level as the gravels 

 of Titchfield and elsewhere. 



Mr. Evans remarked that the fiint flake from Cams Wood pre- 

 sented no characters such as would prove it to be of palaeolithic 

 age. He was, on the contrary, inclined to regard it as having been 

 derived from the surface. He commented on the height at which 

 the Downton implement had been discovered, which was, however, 

 not so great but that the containing gravels might be of fluviatUe 

 origin. 



Mr. GwTN Jefftets thought that if the beds at Cams Wood were 

 marine, some remains of marine organisms might be found in them. 

 If these were absent, he should rather be inclined to regard them as 

 fluviatile. 



Mr. J. W, Flower contended that the gravel at Downton could 

 not be of fluviatile origin. He thought, indeed, that the gravel was 

 actually at a higher level than the present source of the river. If 

 this were so, he maintained that the transport of the gravel by 

 fluviatile action was impossible. He further observed that gravels 

 precisely similar, also containing implements, had now been found, 

 as well in the Hampshire area as elsewhere, the transport of which, 

 in his view, could not possibly be attributed to any existing rivers.
