In 1867 Mr. Delfortrie (B. 136) published a notice of prehistoric antiquities of the Neolithic Age found in the course of excavations for the improvement of the town of Bordeaux, which point to the existence of some kind of marsh dwelling in the very centre of the town. Attention was first directed to the matter by the quantity of bones thrown up from the lower part of the excavations, among which Delfortrie detected some worked ones, and associated with them were various stone and flint implements. In regard to the osseous remains, he observes that the lower jaws of ruminants, which were relatively in great abundance, had their incisor teeth purposely removed, but the molars were retained. On the other hand, the upper jaws were entirely absent or broken, like all other marrow bones. At three different points forming an almost equilateral triangle of 200 mètres the side, he procured sections of these street cuttings, in all of which the succession of strata and relics indicated similar conditions. At one point he gives the following details of a section:-- Mètres. A. Earth and subsoil } 4· B. Terramare of Gallo-Roman period } C. Marine bed with shells ·10 D. Sandy peat ·50 E. Bed of ashes with oyster shells, worked bones, etc. ·50 F. Lacustrine sand ·45 G. Black peat with sand and gravel 1·55 ---- 7·10 The bones represented the following animals:--Great ox, smaller ox, stag, pig, wild boar, horse (a small kind), goat, sheep, and dog. Mr. Delfortrie thinks the bones of the horse show that the animal was not domesticated. No piles were discovered except in the Gallo-Roman period. The following shells were found in the marine bed C.:--Ostrea edulis, Pecten maximus, Mytilus edulis, Venus decussata, Cardium edule, Mactrea solida, Turbo neritoides, and Trochus cinerarius. The relics were found chiefly in bed E., among the ashes, a few being from the sandy peat above it. These consist of pointers, needles, polishers, spatulæ, arrow-points, and an implement of bone called a whistle; flint saws, a polished celt also of flint, three small polished stone celts of serpentine or quartzite, and about a dozen flint knives. The opinion of the narrator is that there was here a marsh dwelling of the nature of the Kökkenmödings of Denmark which in point of time preceded the Swiss lake-dwellings, but was posterior to the Reindeer Period of Central France.
