the dip to be easterly. I also understood that Prof. Hughes had 

 already concluded that the dislocation in the well was the same 

 as that bringing up the Archaean rocks of Cowleigh Park. The 

 supposed mutual relations of the various rocks of the northern part 

 of West Malvern are shown in fig. 13.

The structure of the portion of Cowleigh Park and North 

 Malvern north-east of the fault affords further evidence in favour 

 of the same view ; but the area is imperfectly exposed, and con- 

 sequently has been misunderstood, and to a certain extent incorrectly 

 described and mapped. 1 The beds here also are evidently in part 

 inverted, the overfolding having taken place from the north-east 

 (see fig. 11, p. 157). A limestone, regarded by Phillips as Woolhope 

 Limestone, and so represented in the Geological Survey map, is 

 clearly the Wenlock Limestone. My friend, Mr. Wickham, who 

 has a close acquaintance with the Silurian of the Malvern district, 

 and has made a special examination of this rock at my request, 

 states that it ' is evidently the W T enlock Limestone, as seen by the 

 nodules, the crinoid-joints, and particularly by the absence of the 

 rusty appearance, so characteristic of the Woolhope Limestone 

 around Malvern.' It may be traced from Mill Coppice in a southerly 

 direction towards Cowleigh Park Parm, dipping westward ; soon, 

 however, it sweeps completely round, and for a short distance runs 

 parallel to its former course, almost touching the road. Neverthe- 

 less, this limb of the fold has a dip similar to that of the other. 

 Shales may be seen both above and below the limestone ; the Lower 

 Ludlow and Wenlock Shales are accordingly both represented here. 

 The shales occupying the concavity of the fold are exposed just
