Journal of the Franklin Institute, Philadelphia, Vol 38 (third series), July-December 1859, with text illustrations, and one (movable) plate, 430 pp. Half-calf, with raised bands. Ex-library, with some scuffing on the spine; also a few stamps on the title page. Nice copy. $150 The volume has many dozens of articles, including the following:
“Supply of Coal”, an interesting approximation of the life of the coal supply, though the common denominator is badly defined. Anyway, the writer was thinking about the future supply of coal, reckoning it at 36,000 years.
Alfred Varley, “On the Physical Theory of Electricity in Submarine Telegraphy, the Electrical Difficulties in Long Circuits...” (on submarine cable communications), pp 52-61, 132-138, 199-206, 259-267;
J.P. Espy, “Joule's Unit Verified”, pp 254-6;
James H. Warner, “Mechanical Expansion Table”, pp 4-5, with a plate exhibiting the table with a 6” long moving indicator affixed by string, in good working order. (This seems to be the only movable table in the whole of the journal.)
