ON THE ERRATIC BLOCKS OF THE BRITISH ISLES. 367 
3 feet 6 inches in diameter, were observed. In contrast to this, Messrs. 
Davis and Stather report that among the 133 large boulders (1 foot and 
upward in diameter) and thousands of smaller ones observed by them on 
four miles of coast between Redcar and Saltburn, not a single Shap 
boulder was seen, nor any Augite-syenite nor Rhomb-porphyry. 
A very valuable series of records come from the valley of the Yorkshire 
Calder, the boulders consisting, as in previous reports, of Lake District 
igneous rocks and some from the Carboniferous series ; but the special 
interest of those now reported is that the route taken by the stones is 
now indicated by the completion of a continuous train of erratics over the 
Walsden Pass at Summit and thence to Todmorden. 
The anomalous and isolated group found at Barnsley is reported upon. 
The constituent boulders include basalts and granites of types not recog- 
nised elsewhere in the district, and the group must be regarded with a 
good deal of suspicion, especially in view of the fact that it is in close 
proximity to a navigable canal. 
Reports are also furnished of the boulders in a remarkable detached 
patch of Boulder-clay at Balby, near Doncaster. At this place was found 
a handsome boulder of Shap granite, the most southerly example yet 
observed on the eastern side of the Pennine Chain. 
It is gratifying to learn that, at the request of the Doncaster Natural 
History and Microscopical Society, this interesting boulder and another 
of Lake District andesite have been placed by the Corporation of Don- 
caster in the Free Library. The Yorkshire records conclude with a report 
upon the stones found in the great crescentic drift-ridges which run across 
the Vale of York respectively at Escrick and at York itself. In both of 
these boulders of Shap granite were found. 
In Lancashire but little has been done during the past year ; but Mr. 
J. W. Stather, of Hull, found a large pebble of Shap granite on the 
shores of the Mersey at the Dingle, near Liverpool. Mr. Lomas found at 
the same place a drusy granite resembling that of Goat Fell, Arran. 
The latter is the first example found in England; but the Rev. 8. N. 
Harrison sends records of both the granites of Arran and a ‘felspar- 
porphyry ’ of the same island, from the Isle of Man. 
The Belfast Field naturalists continue their work in the north-east of 
Treland. It is interesting to observe that Foraminifera are found in 
many of the Boulder-clays of their district. Pebbles of the Riebeckite 
Eurite of Ailsa Craig are very abundant in the Boulder-clays near 
Belfast.
