inhabitants of the Southern coast the place of jet, which is so abundant 
in Yorkshire, as a material for the manufacture of bracelets, beads, 
and similar ornaments. Such ornaments have been found in Romano- 
British sepulchres, but never in those of the primitive inhabitants of 
Britain. The Isle of Purbeck was the principal seat of this manufac¬ 
ture, and the “coal money” is found there in connexion with Samian 
and other pottery. 
Mr. Kenrick also made some remarks on a denarius, presented by 
Mr. Noble, bearing on one side the head of Ceres and the legend 
c. MEMMi c. F. (Caii Filius), and on the other side a captive beneath 
a trophy and c. memmius imperator. It is uncertain to what mem¬ 
ber of the Memmian family or to what event the coin refers. The 
Memmius mentioned in the opening of the poem of Lucretius was 
Caius, and the Memmius of this coin may have been his son ; but 
there is no record in history of the battle to which the trophy and the 
title Imperator refer. One of the Memmian family is said to have 
introduced the Cereal games at Rome, whence the head of Ceres 
appears on their coins. 
Nov. 1.— The Rev. J. Kenrick exhibited a collection of flint 
implements, from the beds of drift gravel in the valley of the Somme, 
near Abbeville, and gave an account of the researches of M. Boucher 
de Perthes and of Messrs. Evans and Prestwich connected with this 
subject. The implements in question bear unequivocal marks of having 
been fashioned by the hand of man, and they have been found in beds 
which geologists call diluvial; hence the conclusion has been drawn, 
that the existence of man upon the earth is to be referred to an earlier 
period of its geological history than had been previously supposed. 
And as the remains of mammalia of extinct species, such as the 
elephant, rhinoceros, hippopotamus and stag, have been found in 
juxtaposition with these implements, the further inference has been 
deduced that man must have been contemporaneous with these extinct 
species. 
Since attention was directed to this subject, evidence confirmatory 
of M. Boucher de Perthes’ discoveries has come to light in England. 
Flint weapons, similar to those found at Abbeville, and connected 
with mammalian remains of extinct species, have been found at Hoxne, 
in Suffolk, by Mr. Evans and Mr. Prestwich, in undisturbed beds of 
diluvial gravel, lying above the boulder clay. The existence of flint 
implements in caves, e. g. at Brixham, along with the bones of animals 
now extinct; and of a coarse pottery united with such remains in
