FROM THE KENDAL AND SEDBERGH DISTRICTS, Lal 
posed, and so semiopaque. What remains is clear, not dichroic, 
and more resembles augite than any thing else. The other, still 
clearer, rather fibrous, and very pale green, is probably a variety of 
hornblende, resembling a secondary product.

The hornblendic character of this rock requires us to remove 
it from the mica-trap group, and class it with the more basic 
diorites. 
This dyke is intrusive in Coniston Limestone, which is indurated 
for a distance of a few feet, and stands up above the dyke, which is 
weathered away (surface-colour rusty brown), and protrudes here 
and there from the grass, being about 4 feet wide, and traceable for 
about 20 or 30 yards. 
(5) Dyke, Kendal Road, 250 yards from 3rd milestone. 
Characters.— Macroscopic. A general resemblance to No. (1), ex- 
cept that the colour is browner, and the mica-plates often larger, 
being not seldom 0-4 inch in diameter; the lustre also is less 
silvery. 
Microscopic. An obscurely crypto-crystalline ground-mass, with 
some resemblance to that of No. (1), containing many filmy brown 
scales and fibres, probably of mica, with granular ferrite, and perhaps 
some apatite. Some of the belonites may be pale-coloured horn- 
blende. There are a few grains of quartz, probably secondary. The 
mica has a general correspondence with that in No. (1). The prin- 
cipal differences between the two slides is that this is without any 
conspicuous calcite or dolomite, or indications of augite or horns 
blende. 
The analysis is as follows :—
