Murloch bay, on the east of Fairheader			560	652 the summit of the cliff
Benvaan, on the south of Murloch				885	This form a platform of chalk, covered with grass
Ballypatrick, 3 miles south from Fairhead				622
Knocklead, an insulated mountain, 2 miles south from Ballycastle	S.W	very small		895	The intersection of the conical section surface of Knocklead with the plane of the chalk stratum, forms a zone completely encircling its middle region. In the exact direction of that plane the stratum of chalk (here interrupted by a deep valley) is resumed on the slope of the opposite mountain to the south. Towards the west it catches the plain near Ardmoy, where pits are opened. At Corky, 6 miles south from Ardmoy, and higher up the same valley, there are also chalk pits. See Dr. Richardson's papers.
Ballycastle, west of the pier	S.W. 17	from 15 to 18		emerging from the sea	The upper limit of the chalk stratum through the line of coast between these points, about 30 miles distant, keeps nearly the level of the sea, vacillating slightly on either side of that level, but seldom rising very high, and probably seldom submerged very deeply beneath it: the same description applies to the opposite island of Rathlin. It is unnecessary here to insert detailed particulars, which will be found represented in the sections of the coast.
Down hill, on the west of the river Bann, in the county of Derry	N.E			emerging from the sea
Benyavenagh			on the north side but little elevated above the sea, on the south about 200 feet
Kedy	N.E	10	550?	600	The deposit here hardly exceeds forty feet
Donald hill			800	900	The deposit here increase in thickness to 100 feet: the upper beds are soft enough to soil the fingers, the lower quite compact.
Ballyness
Benbradagah					The thickness of the deposit here is greatly increased, amounting to no less than 363 feet: it is less regular stratified than usual. Towards its upper extremity it wears the character of considerable detached masses; in Kedy Donald and Ballyness mulattoe is interspersed between the chalk and sandstone, but in Bendradah the appear to be in contact.
