Mr. Edward Hull, B.A., called attention to instances of 
g’lacial striations recently discovered by Mr. G. H. Morton, 
at Liverpool, during a recent visit to that town in connection 
with his duties on the Geological Survey. Mr. Hull was 
kindly conducted by Mr. Morton to the spots where the striae 
are visible. One of these is at the south, the other at the 
north side of the town, and at the latter the extent of surface 
exposed is several hundred square yards. The rock-surfaces 
had been protected by a thick coating of boulder clay, which 
has been removed for brick-making. It is owing to the pro- 
tection thus afforded to the rock that the striations are 
preserved in all their original freshness. The rock belongs 
to the New Red Sandstone, and is a moderately hard reddish- 
brown and yellowish building stone. There are two systems 
of striae, the primary one ranging N.N.W., the secondary 
nearly east and west. Of the latter, the markings are 
comparatively unimportant, but are very clear and sharp. 
The primary striae run in remarkably straight lines — in the 
form of deep groovings and scratches, and the whole surface 
of the sandstone is worn down to one uniform gently-sloping 
plane. 
It appeared evident, from the directions of the striae, that 
they had been produced by icebergs coming from the north, 
in all probability from the Cumberland mountains, where 
glaciers are known to have existed during the period of the 
boulder clay, or rather earlier. The secondary groovings 
might have been produced by bergs coming from North 
Wales, but this appeared very problematical. The interest 
attached to these cases of glaciation was stated to arise from 
their position at so great a distance from the Cumberland 
range. In the immediate neighbourhood of these mountains, 
as also in that of North Wales, ice-moulded surfaces have 
frequently been observed, but never before on the New Red 
Sandstone of Lancashire or Cheshire. (See Mem. Lit. and
