constant habit of procuring it*. Endeavours have lately 

 been made to discover the mine, but, as far as we yet know, 

 to no purpose. 



The tipper specimen was lent me by Sir J. Banks, who 

 bought it of an Irishman who brought some to London to 

 sell to the curious ; and this was one of his largest specimens. 

 It is formed of flattish pieces, or lamellated, as if it had been 

 rolled up and beaten about very irregularly, as Sir J. Banks 

 truly remarks, so that it may be called entirely shapeless. It 

 was cut in two at the mint, which helped to discover this 

 foliated appearance ; and also, that it contained grains of 

 whitish quartz and an ochraceous gritty clay {see the cut 

 figure). A piece of soft lightish schistus, or slate, with a. 

 gray appearance on the inside is to be seen in it. The 

 external colour is somewhat redder than where it is broken or 

 cut. Mr. Blackford kindly sent me a piece somewhat paler. 



The third figure on the right hand was a piece of a redder 

 cast j that on the left hand was the whitest of any I have 

 seen from Ireland. These two were purchased for me by 

 my friend Colonel Velley. 



The three lower pieces are different coloured specimens, 

 from Lammon tin stream, near Falmouth, in Cornwall. 



* We have been told that lumps of gold of a large size have been till lately 

 used as weights in some of the common shops, and others placed to keep 

 their doors open, in some parts of Ireland, the owners not knowing what 

 they truly were.
