are severally formed, and tlirow considerable light on their production 

 in nature. Alkaline solutions always give rise to blende, never to 

 wurtzite, and the former mineral is also formed under suitable 

 conditions from acid solutions. Only one sulphide of cadmium exists, 

 the differences in colour that have been noticed being due to the 

 relative amounts of light transmitted and reflected. Three forms of 

 sulphide of mercury are known, of which one, cinnabar, is stable, and 

 two (one being the rare mineral metacinnabar) are unstable. The 

 authors conclude by saying, " Enough work has already been done to 

 show that the difference in chemical character between acid and 

 alkaline solutions, therefore, in general between deep-seated and 

 surface solutions, is of vital importance in geochemistry." The 

 microscopic study "was made by Dr. H. E. Merwin. 



3. Paleolithic Man in Jersey. — In the thirty- seventh Annual 

 Bulletin of the Societe Jersiase (1912) there is an account by Mr. J. 

 Sinel of the prehistoric cave-dwelling (Cotte a la Chevre) east of 

 Grosnez Point, St. Ouen, on the north-western coast of Jersey. Here, 

 according to the author, " we have what may be termed a pure eai'ly 

 Mousterian station, free from admixture of other types of relics, 

 and a floor undisturbed by floods or any other agencies." Apart 

 from the Palaeolithic implements, there was obtained the jaw of 

 a large species of deer in a decayed condition. 



Messrs. E. T. Nicolle and J. Sinel contribute a " Report of the 

 resumed Exploration of ' La Cotte', St, Brelade ". Here, again, flint 

 implements, all of Mousterian type, have been found in a cave- 

 dwelling; also remains of RJiinocera.^ antiqiiitatus, reindeer, ox, and 

 horse, which have been identified by Dr. C. W. Andrews ; and, of 

 still greater interest, some teeth of Palseolithic man, described and 

 figured by Dr. A. Keith and Mr. F. H. S. Knowles under the name 

 of Homo JBreladensis}

1. "The Geological History of the Malay Peninsula." By John 

 Brooke Scrivenor, M.A., F.G.S., Geologist to the Government of 

 the Federated Malay States. 



This paper is an attempt to present briefly and in a connected 

 form all the information bearing on the geological history of the 

 Malay Peninsula that has been gathered during the course of 

 economic work since 1903. 



The main points are as follows : — 



During the Mesozoic Era earth-movements took place in a part 

 of the crust which is now the site of the Malay Peninsula. These
