as ornaments by prse- Adamite man. It was however now ac- 

 knowledged by geologists that these "beads" were of natural 

 formation, being fossils of the chalk; and Mr. Henwood had 

 promised to send him a similar formation in flint. 



Dr. Jago asked Mr. Whitley whether he had not to some ex- 

 tent modified his former views on the subject of flint-flakes. The 

 fact of other things being found near them on the surface was of 

 little moment ; but it was matter of great interest whether they 

 were of pur-ely natural formation, or the effect of human handi- 

 craft; and he should like to know whether Mr. Whitley still 

 adhered to his former statement — that he doubted their having 

 been made by human agency. 



Mr. Whitley here exhibited, from his collection, two imple- 

 ments which he said had undoubtedly been made by the hand of 

 man; but one of these clearly belonged to Sir Charles Lyell's 

 " Second Stone Age," and the other was found on the surface. 

 But in those which he had brought from the Valley of the Somme, 

 where he had examined similar objects by hundreds, there was no 

 evidence whatever that they had been made or in any way used 

 by man. He adhered decidedly to the opinion which he expressed 

 two years ago, — that the so-called flint implements of Lyell's 

 "First Stone Age" had been formed by natural causes, and not 

 by the hand of man ; and that in the " Second Stone Age " there 

 were flint flakes of natural formation which had been manipulated 

 and used by man ; while there were other flint implements of un- 

 doubtedly human make. 



The GrULF Stream. — Mr. Whitley next exhibited and ex- 

 plained his Diagram shewing the temperature of sea and air 

 between the Bank of Newfoundland and the west coast of 

 Ireland. He observed that a vessel, crossing the Atlantic, from 

 Newfoundland, on passing out of the Arctic current, got im- 

 mediately into warm water. He was of opinion that no well- 

 defined branch of the Gulf Stream flowed into the Frigid Zone ; 

 but under the influence of the South-west wind, the heated water 

 was drifted northward over a large portion of the North Atlantic 

 Ocean. Eastward from the Bank of Newfoundland the temper- 

 atures of sea and air increased ; but it was not until about the 

 middle of the Atlantic that they became equal ; and on nearing 

 the coast of Ireland the sea lost some portion of its warmth. On 

 the coasts of Cornwall and Devon the temperature of the air in 

 January, owing to ^.he Gulf Stream, was equal to that on the 

 South of France. — After some remarks from Dr. Barham and Mr. 

 Charles Fox, Mr. Whitley observed that near the end of the 

 Bank the sea attained a depth of five miles ; and the cold water,
