    82 SANDRA HERBERT some of the larger nodules is two feet and a half, and the minor one foot and a half; and the conical structure extends to the depth of three or four inches. The direction of the longer axis is placed parallel to the schistose laminae, which pass round the nodules. ® William Fitton, 'Geology' in Phillip P. King, Narrative of a Survey of the Intertropical and Western Coasts of Australia Performed between the Years 1818 and 1822 (London, 1827), vol. 2, p. 585: The Epidote of Port Warrender and Careening Bay, affords an additional proof of the general distribution of that mineral; which though perhaps it may not constitute large masses, seems to be of more frequent occurrence as a component of rocks than has hitherto been supposed. ® Henslow, 'Geological Description of Anglesea', p. 403: Carbonate of lime is very generally disseminated through every part [of the Plas-Newydd dike]. Henslow, 'Geological Description of Anglesea', p. 417: The most interesting phenomena exhibited by this dyke, are the various changes which it assumes in its mineral character. Henslow, 'Geological Description of Anglesea', p. 434: Through this dyke there run several veins of quartz, which also abound in the surrounding rock, a fact which I do not recollect witnessing in any other dyke in Anglesea. Also p. 419: At its [the dyke's] Northern termination the trap has been removed by the continued action of the sea, and its original walls, composed of quartz rock, form a small bay about eighty feet wide. Henslow, 'Geological Description of Anglesea', p. 375: As the limestone passes into the schist [at Gwalchmai], it assumes a fissile character, and scales of chlorite are dispersed over the natural fractures. Henslow, 'Geological Description of Anglesea', p. 432: The whole [mass of trap] assumes a greenish tinge, but the colouring substance does not appear to be of a very crystalline nature, and is probably chlorite.
