As to the Clay-with-Flints, it is inferred that it is not a deposit of 

 definite age, but a residual product, representing a condition of 

 things that may have held through long geologic ages, from the start 

 of the Blackheath Beds to the present time. 



Mr. G. M. Davies gives a penological description of the Chalk, of 

 the Clay-with-Flints (both grey and red), of the Eocene sands, 

 sandstones, and pebble beds. He also describes the presumed 

 allophane originating from the base of the Eocene deposits, and 

 discusses the probable sequence of events -which resulted in the 

 formation and infilling of the pipes and the deposition of the strata 

 overlying the Chalk. 



2. May 7, 1919.— Mr. G. W. Lamplugh, F.B.S., President, in the 



Chair. 



The President said: Major II. "W. Brock, formerly Director of 

 the Geological Survey of Canada, was called upon last year to 

 undertake, on behalf of the War Office, an arduous journey in 

 Palestine, during which he had to devote particular attention to 

 the Dead Sea region. At the request of the officers of the Society, 

 Major Brock has kindly undertaken to tell us something of his 

 observations in the country. It is needless to say that the region 

 is of surpassing interest to geologists, and I am sure that the 

 Fellows will appreciate the opportunity of hearing how its 

 remarkable features have impressed so acute and experienced 

 a field-geologist. 



Major Reginald W. Brock, M.A., F.G.S., then proceeded to 

 deliver his lecture on the Geology of Palestine, his observations 

 being summarized as follows: —
