THE MINERALOGY OF SCOTLAND. 441 
In quartz, with pyrite and chlorite, on the north slopes of Alsait Hill, near 
Tomantoul. 
Argylishire.—At about the summit level of the Devil’s Staircase; in a eneiss 
which shows no trace of chlorite, but only a brown mica, apparently lepido- 
melane. The ilmenite was in thin curved plates. 
Loch Creran, on the south slopes of Fraochaidh, in chlorite and quartz. 
Forfarshire.—With finely crystallised chlorite, in quartz veins, about three 
miles from the foot of Glen Effock, Tarfside. 
In pegmatitic veins, on the north-west side of Garlat Hill, in the same dis- 
trict. The veins carry graphic combinations of quartz and white orthoclase, 
with crystallised kyanite (in twins), and muscovite. Also with kyanite, on the 
south-west side of the same hill. 
Ilmenite also occurs in “primitive limestone ;”—at least in that limestone 
which is a member of the same formation as that of the rocks above stated to 
be its matrix. 
I have so found it, associated with sphene, crystallised repidolite, and 
pyrrhotite in Edentian Quarry, on the south side of Tullich Hill, Blair 
Athole. 
With sphene in limestone, with repidolite veins, in a quarry on south side 
of the Garry, opposite Blair Athole. 
In granite, and in syenite it rarely occurs. 
In the coarse-grained veins of the granite of Anguston, in Aberdeenshire, it 
occurs along with orthoclase and oligoclase, sphene, Haughtonite, and 
Allanite. 
In a large syenitic boulder, which lay upon the hill of Ben Bhreck, near 
Tongue, it was associated with a great assemblage of minerals, among which 
were amazon-stone, Babingtonite, sphene, Allanite, and orangite. 
In quartzose veins of the granite quarry at Cassencarie, Dumfriesshire, 
with chlorite and epidote. 
It is worthy of note that I have never found this mineral in Hebridian 
gneiss. 
From among this large range of localities I have analysed the mineral from 
the following :— 
1. Found in plicated crystals, imbedded in quartz, with chlorite and talc, 
at Vanleep, Hillswick, Shetland. Magnetite in crystals also occurs here. The 
crystals of ilmenite are from one to two inches in length and breadth, by 
one-eighth in thickness. They are much plicated, following the curvatures of 
the quartz.
