‎Scarce offprint issue, with author's presentation inscription, of Wilde's important contribution to the quantitative relations of the physical and chemical forces especially in relation to batteries. Henry Wilde (1833 - 1919) a wealthy individual from Manchester, England who used his self-made fortune to indulge his interest in electrical engineering. He invented the dynamo-electric machine, or self-energising dynamo, published in 1866. The machine was considered remarkable at the time, especially since Wilde was fond of spectacular demonstrations, such as the ability of his machine to cause iron bars to melt.‎
