WiLLETT, H. Sixth, Seventh, Eighth, and Ninth Quarterly Reports 

 on the Sub-Wealden Exploration. 8vo. Brighton. 



Contain an account of the boring down to 1030 feet. Details of the 

 mode of working by the Diamond Boring Company are given. There 

 are also notes on the bituminous shales in the Kimeridge Clay and of 

 the gypsum in the Purbeck Beds. 



The Geological Reports, by W. Topley, appended to the Sixth and 

 Seventh of these respectively, describe the Kimeridge Clay from 

 376 feet to 656 feet, noting the mineral character of the beds and the 

 fossils obtained from them, and continue the description to 1000 feet. 

 Oxford-Clay fossils were obtained from near the bottom. W. T.

The cutting on the London and North- Western Railway between the 

 station and Clifton Road showed Drift over Lias, the former consisting 

 of sand and gravel over stony clay. The author enters into the ques- 

 tion of the glacial origin of the beds, and the direction from which the 

 materials must have come, and concludes that all the Drift is the result 

 of one process while the land was sinking, the materials being derived 

 at first from the neighbourhood and then from greater distances. W. W.

 Describes the great pit in Cyrena brick-earth. The brick-earth is 

 nearly 20 feet thick ; in one part it rests directly on London Clay ; in 

 another place a thin band of shingly gravel intervenes. The surface 

 is 28 feet above Thames high- water mark. The ground forms a low 

 terrace bordering the Roding on one side ; and on the other it slopes 

 gradually down to the Thames. But few remains of Carnivora occur. 

 Elephant-remains are abundant ; there are portions of more than 100 

 individuals in the collection of Sir A. Brady, belonging both to E, 

 antiquus and E. primigenitis. There are three species of Rhinoceros, 

 remains of R. leptorJiinm being the most numerous ; only one frag- 

 ment of Hippopotamus has been found. Remains of Ruminants are 

 abundant, forming one half of the collection. It is very rare to find 

 two or more bones of the same animal together ; but none of the bones 

 are waterworn.
