but none of his descriptions in the least correspond 

 with that under view* ; and it is with regret that 

 on this and many other occasions, the praise of 

 accuracy, though it ought to form the chief ambi-

 that the bricia of Aix, which he compares with 

 the Arleguino, must be the same with that of Alet 

 in the vicinity of that town. His description of 

 Of Aix. the bricia of Aix, in fact, corresponds with the 

 present, as presenting grey, brown, and red spots, 

 on a yellowish base. The same remark may ex-

 with white, grey, and brown fragments ; and which, 

 he adds, is much used and highly esteemed at 

 Paris ; where it is unaccountably called bricia of 

 Memphis. It is surprising that Saussure, who 

 has described Aix and its vicinity, has not indi- 

 cated this singular marble, which was so worthy

 stone of Eygliers above Mont Dauphin, on the 

 right bank of the river Guyl. This is composed 

 * of pebbles chiefly white, grey, and yellow, joined 

 by a reddish cement, and receives the finest polish. 

 Beautiful tables of this marble may be seen at
