before the next layer covered it. A singular proof of this was exhibited in exploring a cromlech in the island of Herm, where a human skull, found in the lower stratum, was curiously covered with snails' shells, which had hibernated upon its surface. The death of these snails (Helix Nemoralis) must have occurred after the falling in of the sides, or second deposit, when being covered over they remained fixed to the spot. This circumstance, with the appearances of the cromlech at L'ancresse, and the observations made at the Creux des Fées, in the parish of St. Saviour's, prove the original state of the dark sepulchral chamber.
About forty urns of different sizes were obtained from the cromlech at L'ancresse, but from the quantity of pottery found therein, not fewer than one hundred varieties of vessels must have been deposited from time to time during the primeval period. The figures of the urns will form the subject of another paper. The largest was about eighteen inches in height, the smallest four.
The markings and zig-zag borders appeared to have been made by the hand with some sharp instrument, during the period of the hardening of the clay in the sun's rays. The clay beads were of various sizes. Some measured two inches in diameter; others were flat, with the perforation counter-sunk. No coin or metal of any sort was discovered, although the greater part of the contents was passed through a sieve, the use of which cannot be too strongly recommended in such researches.
The grinding-troughs were doubtless in use at a very early period, and appear to have been succeeded by the querns, which existed in private families till the introduction of mills. The process of pounding could be well performed by means of the stone mullers here shewn. They were simple rolled pebbles of various sizes, and were used as a pestle, or worked round the trough with the hand. This method is still observed among the natives of India and South America, where rice and other grain is to be pounded. Some of these are worn on one side, others on both sides, until they became wedge-shaped, whilst some are flat at both extremities.
