Magnetic Iron in Quartz

In the year 1796 I found in a gravel walk in Kensington Gardens a rather large pebble, holding magnetic Iron; but not thinking much of it at that time, I only put it out of the public path  and after a few years had elapsed, recollecting it might be a curiosity, I searched it out, and now find it to be an unique, at least as British, especially as the Iron is in veins, and in very neat, though minute, octaedrons. As it leads to some other varieties, I introduce it here with another undescribed as British, which was the case with those figured before at tab. 54.

The lower figure is from the Isle of Wight. The specimen was sent me by Charles Lyel), Esq. It is grey with a crimson hue, sandy, but replete with magnetical Iron resembling the finest dust, and very attractable.
