4. " On Faults in the Drift-gravel at Hitchin, Herts." By J. W. 

 Salter, Esq., F.G.S. 



The author described some faults exhibited in a cutting of the 

 Great Northern Railway, passing through the Chalk and Boulder- 

 clay gravel, and remarked that whatever system of movements 

 affected Tertiary rocks disturbed also the deeper-seated strata, and 

 assigned this as a reason why the older rocks are more faulted and 

 jointed than the newer. 



5. " On some Flint Implements lately found in the Valley of the 

 Little Ouse river, near Thetford." By J. W. Flower, Esq., F.G.S. 



The sands and flint-gravel on the right bank of the river Ouse at 

 Thetford form a terrace 8 to 10 yards above the river, and about 

 40 yards distant from it ; at a spot called Red Hill a large number 

 of flint implements have lately been obtained from this gravel, at 

 from 12 to 15 feet below the surface, and within a foot or less of the 

 chalk on which the gravel rests ; and some were found in the same 

 gravel filling pot-holes in the chalk. 



The author pointed out the exact correspondence, as regards geo- 

 logical position and relations, between the Thetford gravels and the 

 flint-implement-bearing beds of Amiens, Abbeville, Fisherton, Ick- 

 lingham, Hoxne, &c. He further noticed the close resemblance 

 which these implements and some others discovered in England 

 bear to those of the valley of the Somme ; and concluded by ex- 

 pressing his dissent from Mr. Prestwich's conclusions, and stating 

 his own views on their mode of accumulation, remarking that, in 

 his opinion, these implements were manufactured prior to the sever- 

 ance of this island from the continent. 



6. " On some evidences of the Antiquity of Man in Ecuador." 

 By J. S. Wilson, Esq. 



The western slope of the Cordilleras was stated by the author to 

 be occupied with projected volcanic matter distributed in terraces, 

 the most recent of which is but slightly above high-water mark ; the 

 second rises in some places 10 feet above the former, and is well 

 seen in the lower part of the Esmeraldas river and in the valleys of 

 its lower tributaries ; above this rise four other terraces, respectively 

 8, 15, 12, and 6 feet above one another. 



The second terrace contains in many places remains of articles of 

 human art, broken pottery, earthen figures, and fragments of gold 

 ornaments. This pottery stratum is traceable along a line of 80 

 miles of coast, and, by partial observations, is determined to occur 

 under corresponding conditions for a distance of 200 miles more. 



A section at Chancama was also described ; it is 24 miles from 

 the coast, 180 feet above the sea, and 50 feet above the Esmeraldas 

 river, and exhibits undisturbed sea-distributed gravel and sands, 

 6 feet 6 inches in thickness, containing fragments of pottery. 



7. " On the relations of the Tertiarv Formations of the West 

 Indies." By R. J. L. Guppy, Esq., F.G.S. 



In this paper the author first briefly noticed the present state of 

 our knowledge of the different formations occurring in the Caribbean
