XII. A fecond Letter of the Rev . William 
Henry, D. D. to the right honorable the 
Lord Cadogan, P, R. S. concerning the 
Copper Springs in the County of Wicklow 
in Ireland. 
My Lord, Strabane, May 31, 1 732. 
P-eaJ Feb. 1 5,'W" RECEIVED this day the honour ol 
JL your lordfhip’s letter of the 1 8th, and 
mufl confefs the great fatisfadtion, which I felt, in 
finding the account I lent of the copper mines in the 
county of Wicklow, acceptable to your lordlhip. 
It would be too prefuming in me, to think fuch a 
rough account of thefe curiofities worthy of the atten- 
tion of lb great and learned a body as the Royal 
Society : but, as your lordlhip is the moll compe- 
tent judge, and the truly great and learned are better 
pleafed with important dilcoveries in nature, than 
with fine polifhing, I leave it to your lordlhip to 
communicate the account I fent, to the Royal Society, 
in whatever manner you pleafe. One thing I will 
pawn my reputation on, that every tittle in the ac- 
count has the flridtefi: truth to recommend it. 
I did not fee the iron fhovel, which, by lying in 
the water, and being thereby incrufted with copper, 
gave the firft occafion to this important difcovery ; for 
this happened fome time ago • and the fhovel is long 
lincc gone. But I was informed on the fpot of this 
incident by the miners and workmen, of whom there 
were a great number. It was afterwards confirmed to 
me by the managers and proprietors of the mines.
