Now, Dr. Borlase was born at Pendeen, Saint Just, in 1695, 

 and died at Ludgvan, in 1772. In 1722 he was instituted to the 

 Eectory of Ludgvan, and in 1732 he was presented to the Vicarage 

 of St. Just. His Natural History of Cormoall, commenced about 

 1738, was published in 1758. 



Dr. Pryce was born about 1720-1730,t and died at Redruth, 

 in 1790. His Mineralogia CormiUensis, commenced about 1751-5, 

 issued from the press in 1778. 



Mr. Warington Wilkinson Smyth, still (1869) in the prime of 

 life, is Chief Inspector of the Mines of the Crown and of the 

 Duchy of Cornwall, as well as Lecturer on Mining and Miner- 

 alogy in the Eoyal School of Mines. 



Now, as Dr. Borlase was born in 1695, and as — according to 

 his statement — yellow copper-ore was wasted about 1698, it is 

 plain that at the time of this waste he must have been in his 

 third year. 



Of Dr. Pryce's birth the exact period is unknown ; J but it is 

 believed that at his death, in 1790, he was little, if at all, more 

 than sixty years of age; in 1708, therefore, when it is alleged 

 that black copper-ore was thrown away, he was yet unborn. 



As Mr. Smyth is still alive, it is obvious that the rejection of 

 vitreous copper, which he represents to have taken place at Saint 

 Just early in the last century, must have occurred long before his 

 birth. Moreover, Dr. Borlase — who was descended from a County 

 family long established in the neighbourhood, who was born at 

 Saint Just, and who was for many years Vicar of the Parish — 

 must, at that very time, have lived on, or immediately near, the 

 spot, yet he makes no mention of the circumstance.

f The Eegistry of his Baptism has been sought at Eedruth and Cam- 

 borne, in this County, and at Newtown, Llanwnog, and Swansea, in Wales ; but 

 without avail. He was descended froin an eminent family, long established 

 at Newtown Hall, in Montgomeryshire ; of which, Sir Edward Manley Pryce, 

 the last Baronet, died in 1791, without issue.
