ON THE ERRATIC BLOCKS OF THE BRITISH ISLES. 351 
Alverley.—| mile N.W. of Alverley—Barrowdale andesite 6 x4 x 4 
inches. This is one mile 8.W. by W. of Balby. 
Stapleton Park.—24 miles 8. of Knottingley—Lake District volcanic 
ash 18 x 10 x 6 inches. 
Lound, near Retford.—14 mile E. of the village of Lound—Magnesian 
limestone, grits, and a small fragment of volcanic rock, probably Lake 
District volcanic. 
Reported by KE. Hawkswortu, Rothwell Haigh, near Leeds. 
Silurian grit, hematite. 
Reported by L. GuaveERt, jun., Sheffield. 
Hornsea.—In a series of rocks sent to me (J. H. H.) by Mr. Glauert, 
and collected on the shore at Hornsea, are two exactly similar to the 
olivine dolerite of Fans, Berwickshire. 
Reported by Professor P. F. Kunpauy. 
Pateley Bridge.—At head of Colthouse Gill, 850 feet O.D., fragments 
of the ‘shell bed.’ These erratics are further up the valley and at a much 
higher altitude than any known outcrop of the shell bed on the south 
side of the Nidd Valley. 
Transmitted by the East Riding Boulder Committee (J. W. STATHER, 
Secretary). 
Reported by the Rev. E. Mauer Cote. 
Wetwang.—In the driftless area round the vicarage the scanty soil 
covering the chalk contains large numbers of quartz pebbles. 
Reported by G. W. Mactrurk. 
South Cave.—At 200 feet O.D., near the railway station, a fine 
specimen of Ammonites fibulatus in a bed of rounded chalk gravel. On 
the Beverley Road, at 125 feet O.D., a specimen of Dactylioceras (Ammo- 
nites) commune. 
The occurrence of these two very fine specimens of ammonites from 
the Upper Lias is a striking fact, as the Lias outcrop lies about a mile 
i a a to the west, and the Upper Lias is very feebly represented, 
1f at all. 
IstE or Man. 
Reported by T. Axon, of Stockport. 
Glen May.—A boulder of grey granite about 9 feet in length. 
[The rock is characterised by the occurrence of biotite and light grey 
idiomorphic crystals of felspar with zoned structure. It much resembles 
a granite collected by Mr. Axon and the writer near the eastern end of 
the clints of Dromore, Kirkcudbrightshire—P. F. K.]
