76 THE ESSEX NATURALIST. good scraper ; no locality is given to this or to the next, No. 50a, a small flint fabricator. Joyden's Wood. These specimens are a poor lot, and include one or two scrapers (No. 70e is the best) and one waste chip (No. 34a) which is undoubtedly human. There are two equally undoubtedly accidental pieces (Nos. 38 and 89a), and a few doubtful ones. River Thames ? No. 11. (Plate X., fig. 4.) This is a very fine large flaked and ground flint axe. No locality is given, but from its technique and patination one can feel no practical doubt that it is a specimen dredged from the bed of the River Thames. Size 229 x 87 x 43 mm. Kentish ? No. 24. There is again no locality for this implement, but it is one of the narrow chipped, rather pick-like axes or chisels which are very typical of Kent. Dunstable ? There are four pieces, of which the only record is that they were presented by Worthington Smith. No. 31e is a very good scraper. No. 41a is a scraper, Nos. 124b and 124c are two flakes. Swanscombe. No. 886 is a broken implement, probably the butt-end of an adze, as it is flat on one side ; it belongs to the "end of celt" group. No. 119b. This is either a Neolithic waste chip with (probably accidentally) abraded edges, or perhaps even more probably, a Strike-a-light of the historical period. No. 36d. (Plate X., fig. 5.) This is marked "Swanscombe," but it is certainly not from the Chellean gravel ; it is a Neolithic "Thames pick," dredged from the bed of the river. Size 102 x 52 x 35 mm. No. 62 (Plate X., fig. 6) is another example of the same group, but rather broader. No. 30d. This is a third example of these pick-like forms, ochreous and unabraded ; it may possibly be Palaeolithic ; it
