108 W. WHITAKER ADDRESS: GEOLOGICAL 



In a Report to tlie London County Conncil " on tlie Possibility of 

 obtaining a Supply of Water for London witbin tbe Tbames Basin," 

 tbe supply already got from Hertfordshire was noticed by Prof. 

 A. H. Green and myself, but we did not suggest any extension 

 thereof. * 



The Report, by Mr. (now Sir) A. R. Binnie, "On the London 

 "Water Supply from the Thames and Lea," is clearly of importance 

 to Hertfordshire, the character of the Valley of the Lea and the 

 quantity of water taken from that river being specially treated, f 



A paper, by Mr. J. T. Harrison, " On the Subterranean Water 

 in the Chalk Formation of the Upper Thames" gave rise to a long 

 discussion. Sir H. Gilbert referred to the percolation-experiments, 

 rainfall, etc., at Rothamsted, giving elaborate tables ; Mr. Hopkinson 

 took up the tale of rainfall, etc., for the county generally ; Sir J. 

 Evans drew attention to various matters connected with water in 

 the Herts Chalk, and, in his reply, the author also treated of this 

 subject. X 



In this year there was issued a Revised Edition of the Drift Map, 

 Sheet 46, N".E. of the Geological Survey" (Baldock and Hitchin), 

 based on work done on the six-inch maps. 



1892. 



Mr. E. T. Newton described an Iguanodont Tooth from the 

 Lower Chalk (Totternhoe Stone) near Hitchin, which is "of later 

 date than any British Dinosaurian remains hitherto recorded." 

 It is provisionally named Iguanodon nUlii, after our member, 

 Mr. W. Hill. § 



In a pamphlet entitled "The Supply of Water to London in 

 the Near and the Distant Future," Prof. J. L. Lobley makes much 

 reference to the Hertfordshire sources. || 



Mr. J. W. Grover, in his paper "An Explanation of the London 

 "Water Question," advocated taking water from the Valley of the 

 Colne. ^ 



A Report to the London County Council, by Mr. H. L. Cripps, 

 on "The Position of the London Water Companies," contains much 

 matter concerning our county, the powers of the Companies to take 

 water from the Lea (pp. 87-93) and from wells being treated of,
