ial the first paper in the list Professor McKenny Hughes deals with 
flint, its origin and destruction, and the extent to which chipped 
flints are reliable evidence of the presence of man. The paper is 
founded mainly on the series of specimens brought together in the 
Sedgwick Museum at Cambridge. The following paragraph deserves 
serious consideration nowadays: ‘‘ Let us now take a few groups of 
naturally shaped flints. First there are those which are called 
‘Figure Forms’. M. Boucher de Perthes was the first to call 
serious attention to them. He was the man who in 1857 announced 
the discovery of palzeolithic implements in the valley of the Somme; 
and it is often said in reply to those who criticise adversely the 
evidence upon which a more remote antiquity is now claimed for man 
than had been previously supposed, that, the same thing was done in 
the case of Boucher de Perthes’ discoveries. But the rejoinder is 
obvious. Had Boucher de Perthes not supported a correct theory by 
bad evidence the acceptance of his views would not have been so 
long retarded. We cannot in science give a bill of indemnity for 
false reasoning, though it was in support of a suggestion which after- 
wards turned out to be true.” 
Dr. Holst in the second paper gives a short and very clear account 
of the prehistoric flint-mines near Malmo in Southern Sweden. These 
pits are sunk in gigantic erratic blocks of chalk, the largest being 
about 3000 x 1500 x 10-20 feet. 
Though necessarily much smaller, on account of the shattered state 
of the anal these shafts are comparable to those of Grimes Graves, 
which they resemble in having been hewn out with stag’s horn 
picks. The implements and scrap from the sites, however, do not 
closely resemble those from the English locality, and seem to show 
that these mines were worked from the later part of the Neolithic to 
the Early Iron age. 
The third work under review is an excellent piece of archeological 
survey, detailing the camps and graveyards, the rock-shelters and 
trails of the Red Indians in certain parts of New Jersey. It consists 
of a mass of facts well illustrated by maps, plans of rock-shelters, and 
photographs of pottery, of great local interest, but impossible of 
review. It is, however, an illustration of the interest which citizens
