Oxide of Iron

  • Class 3. Metals.
  • Order 1. Homogeneous.
  • Gen. 7. Iron.
  • Spec. 3. Oxide.
  • Div. 3. Amorphous.

In the Isle of Wight, and many other places, there are masses of irony sand, varying in size and thickness; sometimes forming partly in strata, and often in curving pieces, which have been parts of large rounded masses, coating each other more or less regularly, containing much Iron, being very heavy. They are but just so much oxygenized as not to be attractable by the magnet. I have seen much of  the same substance near Bletchingley, Surry. I thought to have finished this subject, and not to have given figures here; but having said thus much, it might seem wrong to leave out any thing worth mentioning. I therefore add this plate for two varieties of these, that less might be wanted towards the completion of a work intended to contain all possible intelligence as to mineral substances, especially as the specimens are remarkable, and have not, to my knowledge, been noticed elsewhere.

The upper figure is a piece from Alum Bay in the Isle of Wight; it is of a moderate size, for those near Bletchingley were very large.

The lower figure is nearly of the same nature, and was sent me from near Dufton. It serves to show how widely the substance is spread, and that it has been considered by others at least as somewhat curious.
