Note 4 — VISIT TO THE COPPER-WORKS OF SWANSEA.
Reading edition
On this point, we refer all who are desirous of pursuing the subject, to a valuable memoir in the Annals of Philosophy, by John Henry Vivian, Esq., F.R.S., the proprietor of the Hafod Works. This paper, we may add, is the standard authority on the subject; and is, with some modification, copied by Drs Ure and Lardner, and by most popular works upon metallurgy.
