Iw 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, re- 
collecting 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, 
octaédrons. 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 tal. 54. 
The lower figure is from the Isle of Wight. The speci- 
men was sent me by Charles Lyell, Esq. It is grey with 
a crimson hue, sandy, but replete with magnetical Iron re- 
sembling the finest dust, and very attractable.
