in these beds always rounded and smooth, seldom angular. 
Angular boulders apparently never imbedded entirely, almost 
always on surface. 
Lossiemouth . — On old sea margin, 20 feet above present sea level, 
conglomerate boulder same as Carlin’s Stone. About 1J miles 
west of Caussie Lighthouse, a large boulder of silicated sand- 
stone on a bill sloping to N.W. with N.W. striae on it. 
Inverugie limestone quarry, strata dip rapidly to north. 
On surface of rock, striae running E. and W. This deviation 
from normal direction perhaps caused by dip of stratum. 
In boulder clay over limestone rocks here, boulders of oolite 
found, which probably came from Boss or Sutherlandshire 
across Moray Firth. 
Portion of an Oolite boulder seen by Convener, which 
found near Duffus school-house, about 125 feet above sea. 
“ Witch Stone,” about quarter mile west of Duffus school, 
250 feet above sea, viz., a large conglomerate boulder, exactly 
similar to Carlin’s Stone, containing nodules of granite, gneiss, 
and purple-coloured quartz. Its longer axis N.W., and 
sharpest end towards that quarter. Hill on which lies, slopes 
that way. Lies on bed of sand. 
On Clarkeley Hill, 1\ miles eastward of Burgh-head, hard 
sandstone rocks striated N.W. On same hill, several boulders 
of granite (both red and grey) and gneiss, lying on hill sloping 
to N.W. One of them, 4x3x2 feet, has its longer axis in 
same direction. They could have come only from N.W., and 
therefore across sea. (Rev. Dr Gordon, Birnie, pointed these 
out to Convener.) 
Hebrides. 
Iona . — Convener found on east side of island at the shore, small 
well-rounded boulder of conglomerate. Heard that similar 
boulders to be seen on west shore of Iona in St Columb’s Bay. 
Conglomerate rocks, said to be in situ , at Inch Kenneth Island, 
forming cliffs 50 feet high, about 10 miles to N.E. The rocks 
in Iona are clay slate. 
N.E. of Cathedral, on shore, hundreds of granite boulders 
(chiefly red variety). Several exceed 20 tons in weight. 
Farther north, in a cultivated field, about 50 feet above sea,
