Deogheda. 
There are sand-hills between the mouth of the Boyne and Lay- 
town which I examined. I observed that small cores and nodules had 
been broken up to obtain flakes. Every nodule or flake was smaller 
than objects of the same kind at Dundrum. I found several small 
flakes with well-marked bulbs of percussion, some of which have been 
used in scraping. I also found one of the bones of a human arm. 
Malahide. 
There are sand-hills lying between this town and the shore opposite 
Donabate station which I examined, and procured small flakes, cores, 
and hammer-stones. I did not observe any black layers on the sides of 
the pits, as the hills would appear to have been planted over with bent 
to prevent denudation; but the flakes and chips which I procured were 
sufficient evidence to me that the same race of flint -workers which 
occupied the sand-hills of the north had extended southwards as far 
as Malahide. The flint supply was evidently old cores and nodules 
like those found at Dundrum and other stations, only that they seem 
to have become smaller and more weathered the farther we proceed 
southward. I believe that in whatever way these flint nodules were 
carried towards the south they must have been sifted by the way, 
the larger ones dropping behind and only the smaller kinds reaching 
as far as Malahide. In addition to the small flakes I have mentioned 
I obtained a flake of the older series. I also found an old core at 
Ealdoyle, and an object of the same class at Howth.

BUNCEAKA. 
Between Buncrana and Fahan, on the eastern shore of Lough 
Swilly, there are sand-hills which I examined during the past summer, 
in company with my son. From pits there we obtained several pieces 
of flint and one nicely dressed flake of a knife-like character, shown 
in PI. XI., fig. 8, two hammer-stones, two anvil-stones, a small longisli 
pebble with two hollows punched on it, somewhat similar to the 
hollows on anvil-stones, but in this instance they are on the edges 
instead of the flat faces : owing to the position of the indented parts 
the stone is narrowed in the centre, and has a likeness to objects 
occasionally described as plummets. There are two specimens of this
