130 Reports and Proceedings — 



cutting in the high road near Apes Down exhibits the dazzling 

 white chalk on one side, and the dark red Woolwich and Reading 

 Beds on the other. 



The following conclusions are drawn by M. Barrois : 



I. — The Cretaceous beds of the Isle of Wight are capable of being 

 divided into the same paloeontological zones as those of the North of 

 France have been by M. Hebert. 



II. — There are three beds of nodules which can be traced from 

 one end of the island to the other that are of stratigraphical import- 

 ance. First, the one at the base of the Inoceramus lahiatus zone, 

 corresponding to the Totternhoe Stone of Oxfordshire, etc. ; secondly, 

 the one in the upper part of the Terehratulina gracilis zone, the 

 ' Chalk Eock ' of Mr. Whitaker ; and thirdly, the base of the Holaster 

 planus zone. 



III. — The form assumed by the chain of Cretaceous hills travers- 

 ing the island and the different inclinations of the beds composing 

 them are easily understood if the existence of the four above- 

 named faults perpendicular to the beds be admitted. 



The paper is illustrated by several woodcuts and an excellent 

 coloured map; there are also lists of the fossils obtained by M. 

 Barrois in the different zones. B. B. W.

1. " Historical and Personal Evidences of Subsidence^ beneath the 

 Sea, mainly if not entirely in the fourteenth and fifteenth centuries, 

 of several tracts of Land which formerly constituted parts of the 

 Isle of Jersey." By R. A. Peacock, Esq., C.E., F.G.S. 



In this paper the author brings forward a great number of details, 

 derived in part from personal observations and in part from ancient 

 documents, to prove that a considerable submergence of land has 

 taken place round the island of Jersey within comparatively recent 

 times. He referred principally to the existence of a submerged 

 forest in the Bay of St. Ouen, evidenced by the existence of stumps 

 of trees in the sea-bottom there, and by the traditional fact that up 

 to quite a late period fees were paid for privileges connected with 

 the forest of St. Ouen, although the forest itself had long previously 

 disappeared beneath the sea. From the evidence it would appear 

 that the submergence took place at the end of the fourteenth or the 

 beginning of the fifteenth century. The author also noticed the 

 occurrence of peat and submarine trees in the little bay of Greve 

 de Lecq on the north side of Jerse}', and especially referred to the 

 evidence afforded by the Ecrehous rocks and Maitre Isle, there 

 having been in the latter a priory or chapel, supported by rents de- 

 rived from the parish of Ecrehous, which is now represented only by 

 a small islet, with the ruins of an ecclesiastical building upon it, and 

 a range of rocks protruding but little above the sea.
