225, 1. 3, contributed to the effect*,—* At the conclusion of 
his work on Veins, M. Werner particularly recommends the 
Mines of Konigsberg (transl. p. 53), and of the Peak of 
Derbyshire (p. 130), where these anomalies were there stated 
to occur, to the careful study of Mineralogists. Mr. B., 
though a native of the latter district, (P.M. xlu. p. 123,) 
may perhaps hereafter be thought, to have added but little 
to the knowledge thereof. 
1.13, ceases to contain any ore+.—t Similar facts, I 
believe, with regard to Mines in the north-west of York- 
shire, or in Durham, occurred to Mr. John Hutchinson, 
more than a century ago, and were in 1749 published im 
his Works, vol. xii. p. 253, which were unknown to me, 
until very lately, Rep. i.‘245. It has too commonly been 
found, that the Veins in the lower part of the Ist Limestone 
became dead, or contained spars only, considerably before the 
Miners reached the Ist Toadstone, in sinking in these Veins. 
1. 20, but in very small quantities .—{ See Rep. i. 250: 
in Gang Mine, (Rep. i. 258) the short branches of veins in 
the Ist Toadstone, were so very productive, that the late 
Mr. Joshua Gregory, the overseer, (see my Note on p. 226) 
has assured me, that not less than 1000/. worth of ore was 
obtained therefrom ! !

Note on p. 93. 
1. 24, seams of clayt.—t The thickest of these way- 
boards, sometimes divide the Veins, according to the in- 
formation of Mr. Joshua Gregory, Rep. i. 245, and my Ist 
Letter, vol. xlii. p. 58 Note.—Since the same was written, 
I lament to have read of the death of this able and truly re- 
spectable individual, (Mont. Mag. xxxy. p. 501). 
Mr. Gregory had came to town, in the beginning of May, 
on the businesses of the Cromford and Mearbrook Soughs, 
(Rep, i. 329 and 330), and the Gang Mine, of which last 
he was the Manager ; but finding himself very unwell, he set 
off rather suddenly, on his return home; which he never 
reached !, but after an illness of some duration, died at 
Market-Street, in Hertfordshire, aged 60 years. His loss, 
to the proprietors, of the most considerable Mine at present 
in Derbyshire, will be most severely felt, as well as by his 
relatives and friends ; and by none is his loss more sincerely 
lamented, than myself,
