Sulphate of liaryten in small crystals lining fissures, and in compact veins in the ankcritc. Though quite insoluble, this sub- stance can be decomposed by heated solutions of alkaline carbonates; i'.nd when these are cooled it is re-formed and deposited.* It has probably been introduced in tiiis way into this vein. I shall endeavour in the following remarks to state the manner in which these minerals occur in the conqjlicated which fills this vein, and their probable origin. Let the reader then imagine that he is standing on the side of the deep ravine of the tireat Village Kiver, looking into a rocky excavation in which the minerals above mentioned appear to be together in the most inextricable confusion, in great irregular cracks of the slaty rocks, and he will be able, perhaps, to wade through the following description. The ankerite should evidently be considered the veinstone, as it surrounds and includes all the other contents of the vein, and greatly exceeds them in quantity. Where not exposed, it is white and coarsely crystalline. On exposure it becomes yellowish ; and near the surface, as well as on the sides of fissures, it is decomposed, leaving a residue of yellow ochrey hydrous peroxide of iron. In some parts of the vein, the ankerite is intimately mixed with crystals and veinlets of yellowish spathose iron. The red ochrey iron ore occurs in minor veins and irregular ma
