The above, in conjunction with the occurrence on which this paper is 

 based, is a fairly complete account of all recorded occurrences of the metal

 from the point of view of (1) the physiography, (2) the geology and the 

 petrography, of the coimtry ; and, further, to endeavour to trace the nietal 

 to its original source.
