Sections in the Bunter sandstone are to be seen in manylocalities near Belfast; notably, along the Shore Road,ripple-marked sandstones occur at the brickworks (SkegonielAvenue) and at Fortwilliam Park ; on the shore at White-house and Macedon, in the County Antrim; while in theCounty Down a fine section may be seen at the nowdisused quarry near y. St. J. PhilHfs. SCRAHO HILL NORTH QUARRY. The beds consist of soft bright red and yellow variegatedsandstones, sometimes false bedded. These beds mergeinsensibly into beds of very similar character that have beenreferred to as belonging to the Keuper series of sand-stones, red, white, and purplish, without any intermediatebasement conglomerate. Keuper.— The Keuper Sandstone is admirably ex-posed in the quarries on the sides of Scrabo Hill, near Stratigraphical Geology. 79 Newtownards. Here the beds are frequently ripple-marked,or show suncracks, and occasionally rain pitting, with thelucidity of a text-book diagram. Frequent layers of clayseparate the massive beds of sandstone. False bedding isto be frecjuently observed, particularly in the sides of therock faces of the passage leading into the main quarry tothe south of the hill. The rock is extensively quarried forbuilding stone, and, if carefully selected, yields an excell
