to have a globular structure like the oolite. The globules are 

 extremely small, and are attached together by a small portion 

 of clay, which is easily washed out by water. When a por- 

 tion of the mineral, which has fallen to powder in the air, is 

 treated with muriatic acid the brown colour disappears, and the 

 globules become clear, resembling pure carbonate of iron. 

 They dissolve slowly but totally. When analyzed 200 paits

 The name of globular, or oolitic argillaceous carbonate of iron, 

 is proposed for it. — Annates des Mines, iv. p. 633. 



2. Conite. — Dr. Mac CuUoch, in his account of the Western 

 Isles of Scotland, described a new mineral, which he found in 

 Mull and in Glen Farg, and to which, from its powdery form, 

 the name of conite was given. Since this he has discovered it 

 in the trap of the Kilkpatrick hills and also in Sky. 



3. Tin Mines of Banca, &c. — The tin mines of the Malay 

 Peninsula are confined between the 10th degree of north and 

 the 6th degree of south latitude. It is in the isle of Junck- 

 Ceylon, that this metal is the most abundant : the produce sur- 

 passing sometimes 800 tons per annum. 



Quidah, Prio, and Pera, ports of the Peninsula, are places 

 to which the natives bring large quantities of tin from the inte- 

 rior. It is there sold for ten or twelve dollars, or three pounds 

 sterling per picul, weighing 133 pounds, equal to forty-eight 

 pounds sterling the ton, and it is resold in China at eighty pounds 

 the ton. 



The tin of the isles of Banca and Lingin is always at a less 

 price ; and it is said, that the Dutch made an arrangement 

 with the Malayan merchants of Banca, by which the latter were 

 to sell it to them at six dollars the picul. In certain years more
