I. The above is a rough classification of 2,070 boulders (above a foot in diameter) noted on the Holderness coast between Withernsea and Hornsea, a distance of 14 miles, during the summer of 1895. II. All the boulders tabulated in sections A, B, C, D, E, G, H in the above table were in situ in the clay, or were close to the boulder clay cliff from which they were recently fallen. In section F, however, a large group of boulders occurred at about 'half-tide,' and these are inIcluded in the table. · III. Table I. gives the actual number of boulders noted in the different sections of coast. Table II. gives the percentage of the different classes of the rocks. IV. The largest boulder seen was a block of Carboniferous limestone on the beach near Mappleton (85 inches x 31 inches x 30 inches +). Many others approach this size. A block of garnetiferous schist was noted at base of cliff near Cowden, 22 inches x 30 inches x 13 inches. SOUTH WALES. GLAMORGANSHire. Communicated by the Cardiff Society of Naturalists. Reported by Mr. J. STORRIE. Pencoed, Bridgend Fragments of indeterminable marine shells; chert from Lias and Carboniferous limestone; no chalk flints; 4 or 5 Lower Lias limestone with Gryphaa incurra: 3 white cherty sandstone from U. Trias of St. Mary Hill; 7 or 8 Rhætic sandstones, with fossils from St. Mary Hill; 2 or 3 dolomitic breccia; Pennant Grit; Cockshot rock; over 100 Millstone Grit; 40 to 50 Carboniferous limestone; 35 Old Red sandstone, besides pebbles; 1 black micaceous flag (probably Llandeilo); 7 grits and yellow sandstones (probably Silurian); 1 fossiliferous Wenlock limestone; 2 granites (specimens mislaid); 3 trap'; 1 brecciated 'trap'; 3 basalts; 1 porphyritic diabase (amygdaloidal); 1 volcanic ash; 1 rhyolite, showing macroscopic flow structure; 1 gabbro; 1 green rock with white chalcedony. Some of these have been sectioned and submitted to petrologists, who note the following facts: One was identified with the gabbro of St. David's Head; a felsite bore some resemblance to the pre-Cambrian rocks of Pembrokeshire; 2 or 3 acid rocks, brecciated felsites, and tuffs were very like Carnarvonshire rocks, especially those of the Lleyn promontory. None was recognised as belonging to the volcanic rocks of the neighbourhood of Fishguard, of Mid Wales, or of any place further north than Carnarvonshire. From these data it is concluded that the movement of transport was from the west or north-west. Some were of such a general character that it was impossible to locate them. IRELAND. Co. Down. Communicated by the Belfast Naturalists' Field Club. Coast road between Ballymartin and Annalong 1 Granite from Slievh Lawagan, Mourne Mountains. Holywood Olivine gabbro, possibly from Slemish. The boulder was embedded in clay containing fragments of flint, chalk, basalt, and quartzite. Island Hill, Strangford Lough— 2 Ordovician grits. Rough Island, Strangford Lough— Boulder showing junction of granite and Ordovician grit with vein of eurite; Co. ANTRIM. St. Nicholas, Carrickfergus Large boulder of unidentified rock in fossiliferous Boulder Clay, containing a fragment of eurite from Tornamoney (coast of Antrim) St. John's Whitehouse, on shore opposite Macedon— 1 fresh olivine dolerite, derived from one of the volcanic necks of Antrim. The stone is perched on a pedestal of Carboniferous limestone. Its upper surface is sculptured with concentric circles like those on cover-slabs of Kist-vaens. Some Suffolk Well-sections. By W.
