Gives a short topographical description, dividing the island into a 



northern and a southern massif', in the south he describes the Under- 



cliff section from the Gault to the Chalk Marl, noticing the similarity 



of the U. Greensand to the " gaize " of Argonne, and pointing out that the 



Chalk Marl (zone of Scaphites cequulis) is the highest bed here exposed, 



on St. Catherine's Down, tfec. He next describes the ridge of Chalk 



which stretches across the centre of the island, discusses the several 



faults which cut across this range, and finds the Chalk divisible into 



the same 9 divisions as in the N. of France (see Geological Record for 



1874, p. 366). The plate is a map showing the area of the various 



subdivisions, with 3 sections. A. J. J-B.

The region treated of is included between the Cretaceous outcrop 

 on the W. and the Wealden anticlinal on the E., while it is limiV^d 

 N. and S. by two parallel anticlinal folds, the axis of Kingsclore on the 

 N. and the axis of the Isles of Wight and Purbeck on the S. The 

 Chalk of this region forms a complete basin, the regularity of which, 

 however, is interrupted by a median anticlinal, which the author calls 

 the axis of Winchester ; this stretches from Petersfield, through Win- 

 chester, to the Vale of Warminster, and divides the Hampshire Ter- 

 tiary Basin into two — a southern synclinal called that of Hampshire 

 proper, and a northern called the " Basin of Whitchurch " ; the latter 

 is much shallower, and contains no Tertiary deposits later than the 

 London Clay. The Chalk is divided into horizons, the uppermost of 

 which (Zone a Belemnitelles) only occurs in the central area of the 

 basin ; he believes that it never extended northward under the Ter- 

 tiary outliers, below which he finds a lower zone of Chalk (Craie k 

 Marsupites) ; and he concludes that the Winchester anticlinal began to 

 be uplifted between the deposition of these two zones. He then con- 

 siders post-Cretaceous oscillations. The axis of Kingsclere is identified 

 with that of Artois ; and though in England it disturbs nothing newer 

 than Woolwich Beds, in France M. Eocene beds are affected by it ; he 

 therefore refers its production to U. Eocene times. The axis of Win- 

 chester is identified with that of Bresle ; and its second upheaval was 

 probably completed about the same time. The Isle of Wight axis is 

 referable to the same period, and is a continuation of that of Bray. 

 Lastly, the line of Dover Straits can have no connexion with this sys-
