A pophjrl- 

 litc. 



Stilbite. 



Analcimc. 



APOPHYLLITE. 



In Sky, near Loch Brittle. In the Kilpatrick Hills. 



8TILBITE. 



In Sky. In the Kilpatrick Hills, Near Stone- 

 haven, in Fife. In the Shiant Isles. In Staffa and 

 Canna. In all these places in traps. In Arran in 

 granite. At Strontian in a granite vein. In Kerrera, 

 red, in argillaceous schist ; being the only instance, I 

 believe, of that association. 



ANALCIMB. 



In Sky, Canna, Staffa, Ulva, and Mull. In the Kil- 

 patrick Hills. In Edinburgh castle rock^and in Salis- 

 bury Crags. In Dumbarton castle rock. In Sky it is 

 often transparent. In the Kilpatrick Hills it passes 

 by a complete transition into prehnite. The primitive 

 form occurs at Talisker, in Sky, 



MESOTYPE. 



Mesotype. In Glen Farg. In Sky. 

 Staffa, and Ayrshire. 



In Arran, the Shiant Isles, 



NADELSTEIN. 



Nadelstein. 



In the Kilpatrick Hills. In Sky. In Arran. The 

 radiated variety, called natrolite, occurs in Staffa, and 

 near Burntisland in Fife. The nadelstein of Talisker 

 and Dunvegan in Sky, often resembles the finest cot- 

 ton, or flaw silk, and is so light as to float in water. 



CHABASIK. 



Chabasie. I n Sky, at the Stoor, and at Talisker, in traps. 



WAVELLITE. 



Wavellite. 



In the Shiant Isles, in an indulated shale or flinty 

 slate of the secondary class, which belongs to the coal 

 strata of the Western Islands, and is indurated by the 

 vicinity of trap. 



OLIVINE. 



Olivine. 



Adularia. 



Augite. 



This is rare in Scotland. In Sky, in trap, near Loch 

 Brittle ; forming half the mass of the rock. 



ADULAUIA. 



In granite in Arran. In granitic veins in micaceous 

 schist in Cairn Lia. This mineral is very rare even in 

 those localities. 



AUGITE. 



In Rum, in trap rocks, with felspar ; very remark- 

 able, and of a very large size. In St. Kilda, Arran, 

 Sky, &c. in a similar manner. In Tirey it is found in 

 white primary limestone, and sometimes regularly crys- 

 tallized. 



SAIII.I I i: 



Sahlie. 



In Tirey, often crystallized, and of various colours, 

 forming very beautiful' specimens. In Harris equally 

 or more various, and often of a dark brown. In Glen 



El*, silvery white. In Rannoch, pale green. In Glen 

 Tilt, white, massive, in large beds; where it is asso- 

 ciated with tremolite, rs it also is in Tirey ; decom- 

 posing alto into a very tenacious and unctuous clay. 



ANDALCBITB. 



Iii Abcrdeenshire, in granite. 



CALCABEOUS 8PAB. 



Green. Coloured by green earth, of a light green. 

 In Rum. Of a dark green, by common chlorite in 

 Bute. Those varieties are extremely singular and rare. 



YeU-.tv. Crystallized in the inverse rhomb. In the 

 primitive rhomb. In Sky also. The varieties found 

 at Strontian are so well known that I need not enu- 

 merate them. 



IIYBRATE OF MAGNESIA. 



In Unst in Shetland, and in Balta. Found in ser- 

 pentine and in talc schist. 



OXYDULOCB IBON. 



Octahedral. In hyptrsthene rock in Sky. In talc 

 and in chlorite at Fiflswick and at Unst in Shetland. * 

 In chlorite schist in Bute. 



Micaceous. In veins or nests, in clay slate, at Dun- 

 In dispersed grains, in gneiss and granite, in 



keld. 



Shetland. In the same manner in a com pacF grey (old 

 red) sandstone. 



Specular-volcanic. In trap veins in Perthshire. This 

 is crystallized in prolonged hexagonal plates, and re- 

 sembles that of Vesuvius. 



BOG IBON ORE. 



The resinous variety. In Foula, Shetland. This ^ ta " 

 variety is not common, and resembles, in its lustre and "^ 

 fracture, those Hungarian jaspers which have been im- 

 properly called pitchstone. 



OXYOE OF CHROME. 



In Unst, in chromate of iron. This new mineral is Oxyde of 

 the pure oxydc of chrome, not the mineral called by Ownm*. 

 this name in Lucas's system ; and is either compact or 

 pulverulent, being sometimes green, at others yellow.

 peffer. In Shetland. At the head of Loch Lochy in
