XXIII. Description and Analysis of a Specimen of 

 Native Iron found at Leadhills, 



By Mr H. M. Dacosta, M. W. S. 



( Bead 2 5tk November 1 8 1 5 J 



This specimen of native iron, was found at Lead- 

 hills in Lanarkshire, associated with galena. The 

 history of its discovery, is as follows : The miners^ 

 on dressing a quantity of ore, were surprised to 

 find, that a portion of it resisted repeated blows 

 of the hammer ; this circumstance led them to 

 examine it more particularly, when it proved to 

 be a particular substance, which they immediate- 

 ly carried to the mine-master, Professor Irvine. 

 I am told it is the second specimen of this rare 

 mineral, which has been met with at Leadhills. 

 Through the politeness of Professor Irvine, I am 

 enabled to present it to the Society.
