During a thunderstorm in France in July, 1858, a peasant-woman, on her way home from the fields, was struck down by lightning. No wound was detected upon her person, but her hair was singed and a part of a silver comb melted. Here metal seems to have conducted the electricity to the body. On the other hand, the traveller Brydone relates a circumstance which happened to a lady who was regarding a thunderstorm from her window. At a flash of lightning her bonnet was reduced to ashes, nothing else about her being affected. Brydone supposes the electric current to have been attracted by the metallic wire which maintained the shape of her bonnet. Hence he proposes that either these wires be abandoned or in times of danger a metallic chain be attached to the bonnet, by which the charge might pass to the earth. Accordingly, we find that it became fashionable in France at that period to wear on the top of the bonnet an ornament of bright metal connecting with a small silver chain dropping down to the ground. At about the same time umbrellas were carried fitted with wires and chain for a similar purpose. In July, 1819, lightning fell upon the prison of Biberach in Suabia, and there struck, in a common apartment, among twenty prisoners, one only--a condemned captain of brigands, who was chained about the waist. A similar arrangement of metal proved fatal in another case. On the 9th of October, 1836, on the coast of Italy, a young man was struck by lightning and killed. It was found that he wore a girdle containing gold coins. Undoubtedly, danger or safety depends on properly placing the conducting object. It may convey the current to the vital organs or it may ward off the stroke. Probably any line of metal parallel with the length of the body when upright would be in some degree a protection. The noted Dr. King once saw a military company receive a discharge of electricity from the clouds upon their bayonets, whence their muskets conducted it to the ground without harm or any painful shock. On the other hand, a battalion of French infantry, while marching between Mouzon and Stenay, June 2, 1849, was struck by lightning, and two men killed, while about two hundred were struck to the ground. Blood flowed from their mouths, ears and noses. This effect appears to have been the result of the concussion. Similar results sometimes follow from heavy discharges of artillery. Uniform testimony goes to show that men in metallic armor have never been fatally injured by lightning. A complete suit of metallic armor embodies the principle of the well-known electrical cage of Faraday. This is simply a basket of wire network with its open side to the ground. If the wire is of proper size and the capacity sufficient, this cage is the most effectual protection possible, unless the walls be of solid iron.
