5. Tynecastle, in west suburbs of Edinburgh. — A basaltic 
boulder examined by Convener and Mr Stevenson, C.E., x 4 x 2 
feet, buried in a knoll of muddy sand, discovered on removal of the 
knoll. The sand contained numerous pebbles of all kinds, hard 
and soft, such as quartz, shale, coal. Height above sea 200 feet. 
Sides of boulder well rounded. Smallest end of boulder pointed 
westward. Both upper and under sides of boulder striated. Striae 
more deeply cut on under than on upper surface. The striae on 
under surface showed they had begun to be formed at east end of 
boulder, probably by the boulder having been pushed towards east, 
over hard rocks. The striae on upper surface showed that the 
tools which formed them had acted on the boulder first at west end. 
6. Grant on . — The sandstone rocks at the Old Quarry near the 
sea were covered by boulder clay, which had embedded in it many 
blocks derived from Linlithgow and Stirling shires. The striae on 
their upper surfaces all run E. and W., viz., a direction parallel 
with the general axis of the Eirth of Eorth {Edin. Neiv Phil. 
Journal for January 1847). 
At Granton Harbour^ on the west side of, at the shore, there are 
two large whinstone boulders, with striae on their upper surfaces, 
the direction of which is W. 3° S. (magnetic). 
7. Leith Docks . — In new Albert Docks excavations were made 
in the boulder clay, in course of which a number of large boulders 
were found. 
They consisted mostly of blue whinstone, also some of quartz, 
limestone, greywacke, sandstone, and black ironstone concretions 
derived from beds of coal and shale. On most of the boulders 
there were smoothed surfaces and striae, bearing nearly the same 
direction, viz., points between W. and 
Among these there were two metcdlic boulders, which, having a 
strange appearance, were brought to the Convener by the Inspector 
of Works ; and to Professor Crum Brown (of Edinburgh University), 
the Convener submitted them for examination. One, nearly spheri- 
cal, measuring 7J inches in circumference, and weighing 26 oz., had 
been found about 4J feet down in the clay bed, among the general 
mass of boulders. The other, more exactly spherical, measured in 
girth 30 inches one way and 31 inches transversely, and weighed 
54 lbs. It was found 10 feet below the top of the boulder clay bed.
