Story of Electricity-John Munro

Telling the history of geographical discoveries, "Book of Discovery" is a record of splendid endurance, of hardships bravely borne, of silent toil, of courage and resolution unequalled in the annals of mankind, of self-sacrifice unrivalled and faithful lives laid ungrudgingly down. Of the many who went forth, the few only attained. It is of these few that this book tells. (From the Preface of the book).
