Kelvin's Latent Invention.

Lord Kelvin's Latest Invention.

Lord Kelvin, now more than 75 years old, has just taken out a patent on an improved device for making soundings at sea. Although his life work has been philosophical rather than mechanical, and has related mainly to the theories that underlie physical phenomena, Lord Kelvin is the author of useful instruments, among them the siphon recorder, for registering cable messages, and the quadrant electrometer.
