Another Topaz has been found near Invercauld, 

 in Aberdeenshire. Its weight, as communicated 

 to me by Colonel Imrie, is 3420 grains, or 7 oun-

 gravity 3.56. It is said, that a distinct crystal, 

 heavier than the preceding one, has been found in 

 the same county, and is now in the possession of a
