“ I have omitted particularly many of the small masses of quartz rock which are visible on the granite, as they would, instead of elucidating, have obscured the explanation which this map is designed to give. The southern side being of a more simple construction admitted of a more real detail, yet in this also I have not pretended to lay down the perpetual and often minute alterations of the schistose rocks with the limestone, since there would not have been room for this purpose: I have contented myself with indicating them in a general way. ”

“ To preserve uniformity in the colours which represent the different rocks I have here also tinged the limestone blue. It is white in nature. It serves to show the entire loss of the stratified character which the limestone so often undergoes in the vicinity of the granite. Specimens from this junction are also in the Society's collection. ”

“ Section of the Isle of Wight, from north to south, shewing the middle range of hills, consisting of strata of chalk, very highly inclined; the horizontal strata inferior to the chalk on the south, (right side of the plate) ; and the vertical strata of Alum Bay to the north, of later date than the chalk. Against the latter the horizontal and alternating series of marine and freshwater strata in Headen Hill, come up almost abruptly. ”

“ The river here divides the stratified rocks from the granite, and has exposed the various junctions which are laid down in the map and described in the paper. It is easy to see how these will sometimes consist of limestone, sometimes of schist or of quartz rock, and sometimes of all the three substances, with the granite. ”

“ Since the greater number of them are represented as if drawn from a point at right angles to the horizon, when they were necessarily taken at an angle often far less than this, it is plain that they will transgress the laws of perspective. ”

“ Represents the actual superposition of the rocks at the Criny, serving to justify the ideal sections which have been already given. The rocks being inaccessible are not however measured. Other indications of a similar order occur in different places, but I thought it unnecessary to represent them.
Fig. 2. Is intended to represent the probable appearance of the strata had they been deposited on the granite. Since the same beds of quartz rock, schist and limestone, are parallel among each other, they should if they had been thus deposited been also found parallel to the granite. ”
