GAI'LISII FORTRESSES ON THE COAST OF BRITTANY. .'321 very luucli reduced in thickness. This porLiuu is, therefore, t'dmost always found broken. (3.) A millstone with its upper face perfectly flat. It is the only specimen of this kind that I have seen. (4.) Eight small flat millstones, of oval form, and measuring about 12 in. by 7 in. The upper face of these is either flat or very sliy,htly convex. The.se millstones from their light- ness were probably supported on the knees by the left hand, ^Yhile the right hand worked a flat muUer-i'ace. The}' are all moi'c or less fractured. A similar millstone was found some few j'cars ago in the oppiduni of Castel jIur, on the sea-coast between Castel Coz and the Pointe du Raz. jl. Grenot discovered a second near Audiernc, in a place near the coast, called Trez-Goarem, where, among some chips of flint and quartz and pieces of very coarse pottery, there were indisputable traces of Roman occupation. (5.) Four round granite pebbles, 10 in. long and from 5 in. to 8 in. in breadth, bearing on one of their faces evident marks of friction. These appear to be millstones in a half- finished state. (6.) The half of a kind of porringer [ecuel/c), nearly G in. in diameter, holding an intermediate place between millstones proper and the stone mortars found in circular habitations in England, but which are entirely wanting in Castel Coz. It is made out of a hard reddish granite with a quantity of quartz cr3'stals. It is also well poli.shed by long use. It was found in the chamber E. A similar object, both as regards its form and dimensions, was found a few years ago under a rock near the town of Tregunc (Finistere), where arc so many menhirs and two rocking-stones. With the exception of the last mentioned article, all these millstones came from the great chamber C. II. — Al)out a hundred mullers {nwldtcs), the greater part of which arc more or less broken, some being round, others flat, and measuring from 2 to 8 in. in diameter. These are simple rolled stones collected from the beach, and require no par- ticular description. One of them, however, has been worked with considerable care, and reminds one of the ordinary mullers used by painters in grinding their colours. 111. — Twenty pestles (pilons), formed of straight long stones brought, like the last mentioned, from the shore, some being round, others flat, from 4 to 8 in. long. (See fig. 2.)
