LETTER jfrom RICHARD KIRWAN, £&£f; F.R.S. 
and M.R.I.A. to the Right Honourable the Earl of 
CHARLEMONT, PRLA. 
My Lorp, 
J BEG leave to lay before your Lordfhip a copy of a letter Read Dee. 
which I juft received from Mr. Miuus, an eminent miner in 5x1789° 
Chefhire: it tends to reftri@ the generality of an obfervation I 
had made on the coal-mines in the neighbourhood of New- 
caftle and Whitehaven, and had unwarily extended to all the 
coal-mines in England. As the Academy has already done me 
the honour to publifh my paper on coal-mines, I feel myfelf 
obliged to fubmit to its confideration, whether it may not be 
proper to publifh this reification of the miftake I had. fallen 
into, and the curious and intelligent remarks that accompany it; _ 
for this purpofe I commit it to your Lordfhip, 
And am, my Lord, 
Your moft obedient and humble fervant, 
RICHARD KIRWAN.
