very common-looking sand sent me from Scarborough by 

 my friend Dr. Travis, since which I have had the pleasure 

 of receiving Iron Sand from Wicklow in Ireland, by fa- 

 vour of Dr. Scott. In examining this it evidently betrayed 

 its habitat by minute particles of gold, besides which it has 

 Octaedral Iron more or less oxidated, and some Cubic 

 Pyrites, Pebbles, &c. 



Again, in July last, my valued friend James Brodie, Esq. 

 sent me some beautiful Arena ponderosa, as it was called, 

 sent by Governor Stewart of Fort St. George from the Ferry 

 of Ardentenny in Argylshire, where, the governor observes, 

 it is found in the greatest abundance, washed out of the 

 banks by the sea ; and what was sent me was as pure as 

 that separated from the others, and somewhat brighter, 

 with octaedral crystals, small, black, abundant, and very 

 attractible. 



The right-hand upper figure is of the pebbles and sand 

 from Hunstanton in a heap, and the particles of iron of 

 the size generally found, by the side. The figure underneath 

 is such as is found when the sea has washed it and oxi- 

 dated it. The five pebhles on the side magnified are three 

 common Quartz pebbles, which compose common sand, 

 and two darker, chiefly Oxide of Iron. The left-hand upper 

 figure is the Irish Sand, and the figures on the side show 

 the Octaedron, Cube, Gold, and Pyrites. Beneath is the 

 outline of a magnet, and the Iron in common as attracted 

 by it at the base. The middle figure is a parcel like that 

 from Scotland, or such as has been separated from the 

 other sands. 



Thus it appears that this sort of Sand, which was hitherto 

 supposed to be found only in America, has now been 

 found in England, Scotland, and Ireland, or the three 

 grand divisions of the British empire. I should think these 

 might be of great use to the proprietors, if properly attended 

 to. I understand Ardentenny is the property of Lord 

 Dunmore,
