Book excerpt: Excerpt from The Geology of the Isle of Wight The onward progress of geological science during more than a quarter of a century since the first edition of the present Memoir appeared has not left the Isle of Wight unaffected. The geological formations on which the beauty of that fair Island so largely depends have been studied in great detail in all parts of the South of England, as well as in foreign countries. The coast sections of the Isle of Wight have even become subjects of discussion and controversy. When, therefore, the first edition of this Memoir was nearly exhausted, and it became necessary to undertake the preparation of a second edition, I felt that no satisfactory progress could be made in this task until the Map of the Island had been first revised and brought abreast of the present condition of Geology. The publication of the large Ordnance Survey Maps on the scale of six inches to a mile supplied for such a revision a far more accurate and convenient basis than was available at the time when the Island was originally mapped by the Geological Survey. Accordingly, Mr. Bristow, the Senior Director, to whom science is mainly indebted for the first Survey Map of the Isle of Wight, and for the Memoir descriptive of the structure of the Island, undertook the serious labour of superintending the preparation of new editions, both of Map and Memoir. In the following Prefatory Note supplied by him he has stated how this work has been carried on under his general supervision. The revision of the Map became in fact a re-survey of the Island, as all the lines were retraced on the ground. It is, however, due to Mr. Bristow to add that the main geological lines remain nearly as he mapped them more than 30 years ago. In the preparation of the present edition of the Memoir so many and important have been the changes required that the work might not unfairly be described as a new one. The revision alike of Map and Memoir has been made under Mr. Bristow's direction and with his co-operation, by two of the officers of the Survey, Mr. C. Reid, who took the tertiary area, and Mr. A. Strahan, who had assigned to him the Secondary Rocks. I have also myself personally visited the Island with Messrs, Reid and Strahan, and read over on the ground the proofs of the following chapters. I will here briefly mention some of the more important alterations and additions. In discussing the relations of the Wealden to the Upper Neocomian Rocks it is shown that these two groups are separated by a sharply-defined lithological demarcation, accompanied by a palæontological break.
