‘vocal situations do really indicate the lines of ancient 
beaches. 
On the north or highest of the two points of Williamlaw, 
and near the summit, are two broad indistinct terraces, whose 
surfaces slope considerably towards the southern or lowest 
point, and also to the west. The crest between the two points 
is a succession of low eminences and intermediate furrows, 
which have no connexion with any of the terraces, but are 
formed of the basset edges of the harder beds. As the dip 
and strike of these correspond in the main with those of the 
slanting ridges below, and as they are separated by similar 
smooth grassy hollows, there can be no doubt but the cause 
assigned by Mr. Kemp for the latter, is the true one. 
At the south foot of Williamlaw, on the opposite bank of 
the Gala, is a broad level grassy plain, formed of diluvium at 
the time the whole valley was under water, and subsequently 
cut through by the existing stream. It reminded me strongly 
of the true terraces near the head of Glen Roy. 
Having now stated, as clearly as I can, the observations that 
occurred to me on a hasty view of these terraces, I have only 
to express a hope that more competent geologists may be in- 
duced to examine them in greater detail. Whether the theory 
proposed by Mr. Kemp be the true one or not, the merit of 
having first discovered, and then worked them out with such 
ability and perseverance, will ever be his own. No one will 
rejoice more than myself to see my objections answered, and 
a cause assigned that shall explain the difficulties and harmo- 
nize with all existing appearances. Nor is this all; the com- 
plete explanation of any set of natural phznomena, lessens 
the difficulty of comprehending otliers, still obscure, to which 
they are allied; and is another step in advance towards the 
future solution of the grand problem, the aggregate causes 
some have produced the existing state of things upon our 
globe.

shire Philosophical Society. 8vo. pp. 160. London, Longman

We have here a very interesting work—the Flora of an important 
district, carefully investigated by an industrious and intelligent prac- 
tical botanist, who has been enabled, by peculiar circumstances, to 
combine with his own the valuable labours of others to a ve 
unusual extent. A preliminary essay, by Professor Phillips, on the 
Physical Geography of Yorkshire, in relation to the distribution of
