been eniployei] : and vve would suggest that on every occasion 

 of danger, or of exploration, a quite new lamp should be em- 

 j)loyed; for there is ahvays a possibility of some particle of coal 

 adhering to lamps that have been in use, which of course will 

 be ignited when tiie lamp becomes red hot, and may communi- 

 cate explosion. The lamp ought not, any more than gunpow- 

 der, to be exposed to avoidable danger. 



IRON IN CAITHNESS. 



There are strong appearances of iron upon the coast, about 

 the Ord of Caithness, and in many places between the Ord and 

 Wick, and to the northward of Wick. The coast of Caithness is 

 remarkable for pretty high rocky cliffs, in which great numbers 

 of veins or perpendicular mineral fissures appear, many of which 

 contain iron ore. Some 'of these have been observed near the 

 old ruinous castle of Girnigo, and the Castle of Arkergil. These 

 veins appear to be bold and roomy, and to contain plenty of 

 good iron ore, from the abundance of a bright red iron eartli 

 found in the surface of them. There is great abundance of bog 

 ore over all the low country of Caithness. In many places it 

 almost covers the whole face of the ground to a considerable 

 depth. It is easily known and distinguished by the friable con- 

 stitution of its misshapen massesj by its external blackish and 

 rusty colour, and by its internal blackish gray colour and granu- 

 lated porous texture. It is always found loose on the surface of 

 the ground in the same manner as float ore, without any con- 

 nexion with the vein or stratum. 



DISCOVERY OF AxN'TIMONY IN BANFFSHIRE. 



A promising appearance of antimony ore has been lately dis- 

 covered on the estate of Lord Fife. This ore, we understand, 

 has been examined by Professor Jameson, who finds that it is 

 the radiated gray antimony, and contains 70 parts antimony and 

 'M of sulphur. We trust this very promising discovery will be 

 ^ igoroubly pursued. 



TWO NEW MINERALS. 



We understand tliat Dr. MacCuUoch (the geologist) has dis- 

 covered two new minerals in Scotland, an account ef which will 

 be given in his woik on the Hebrides. We have obtained the 

 loiiowing sketches of their prominent characters. 



The first is easily recognised by its resemblance to indurated 

 fctcatite or noble serpentine, and by its green colour, on a fresh 

 fracture, shortly turning to black, when it can scarcely be di- 

 stinguished by the eye from jet or drycoal : it is also infusible be- 

 ioie the blowpipe. Dr. M. has given it the name of chloropha- 



fite,
