Extract

There is no department of natural science which is so defective in its general scheme of arrangement as mineralogy; and its sectional grouping is, if possible, still more defective.

Such correlations as are expressed by the terms, “the Micas,”—“the Felspars,”—“ the Garnets,” &c., are only admissible if the substances united in such groups are included under one general formula, and function in a more or less similar manner as rock-formers.

page 56 note * Great Gable, Eskdale, and Harter Fell. The fan-shaped crystalline groups of Harter Fell are very probably chlorite. The nests from the same locality, ranging up to 1 inch in diameter, composed of a “fibrous crystalline” mineral, can hardly be so. As these large nests, a single one of which would suffice for an analysis, can, with “ a little careful hammering, be taken out whole from the rock,” it is much to be regretted that they were not examined ; as a fibrous crystalline green mineral would in all probability prove to be either Kirwanite, or new.

page 72 note * The Old Red Conglomerate at Callendar contains rarely quartz nodules, with chlorite, very similar in appearance to that of Cruach Ardran.
