At the foot of the terminal and almost inaccessible cliff of the hill—name unknown—which towers immediately to the south west of the harbour of Waii or Hoiwig, in Bordöe, Faröe, the writer obtained the specimen—a single one—of which the following is an analysis:

The island of Bordöe, like the most of Faröe, is built up of strata of bedded trap with mural cliffs, which alternate with terraces of grass clad debris. At this part of the island, the terraced trap consists of a wackenitic “claystone,” which is very friable, light in colour, easily disintegrated, and in places tufaceous in aspect. Its amygdaloidal druses are very few and far between.
