234 Reviews—Ightham, a Kentish Village. 
most prevalent in the present map are derived respectively from the 
Carboniferous Limestone and from the Old Red Sandstone. 
Boulders of Carboniferous Limestone are more abuudant than those 
of any other rock, and are so large and so numerous that it is some- 
times difficult to decide from a small outcrop whether the limestone 
is in place or is part of a shifted block. Old Red Sandstone and the 
Carboniferous volcanic rocks likewise contributed their quota of 
boulders. Boulders of rocks entirely foreign to the district are of 
comparatively rare occurrence. The most notable are the blocks of 
granite recognizable as that which occurs in place on the north side 
of Galway Bay. 
From the evidence afforded by the glacial scratchings on surfaces of 
rock and by the direction of transport of boulders, and other material 
incorporated in the drift, it is clear that the ice by which the country 
was overwhelmed had a general movement, from approximately north- 
west to south-east, though with many local deflections due to the 
irregularities of the ground. It is important to note that this 
direction is transverse to the Shannon, and is, moreover, not toward 
the western coast but trends somewhat inland. Post-Glacial deposits, 
consisting of Old River Gravels and Peat, complete the series of rocks 
of the district. 
In the ‘‘ Notes on the Soils and Subsoils,’”’ which are presumably 
intended for farmers, it seems to me unreasonable to give dimensions 
in millimetres and centimetres and weights in grams until the metric 
system is made compulsory in the British Isles. 
At the foot of the map a longitudinal section from the Silurian hills 
on the north-west across the great syncline of Carboniferous rocks with 
a minor anticline in it south-east of Limerick, and then traversing 
between Cahernarry and Knockroe an anticline of Lower Limestone 
overlain on either side by thick beds of basalt and volcanic ash, 
extends to a point one mile west of Ballybrood House. The abrupt 
right angle drawn in the centre of the anticline and the sharp zig- 
zags in the Silurian rocks look rather unnatural. B. Hopson.

GHTHAM and the surrounding districts are sufficiently rich in 
geological and archeological interest to deserve the distinction of 
a monograph. Such a work might have been expected long ago from 
Mr. Benjamin Harrison, with his unrivalled local knowledge. But 
Mr. Harrison, though unsparing of his pen in correspondence, 
exercises excessive self-restraint in committing manuscript to the 
printer; and it has therefore been left to others to take up the work. 
‘When Mr. Bennett, on retirement from the Geological Survey some 
years ago, settled at West Malling, he became an enthusiastic student 
of the neighbouring country ; and feeling, after a while, that Ightham 
needed its historian, he determined personally to supply the want.
