Default John Harrison's 1730 Marine Clock - The Powder of Sympathy


John Harrison's 1730 Marine Chronometer for determining Longitude - Hitherto the Powder of Sympathy / Dog method was in use, PoS heals at a distance despite momentary pain, thus an injured dog was put on a ship, when its bandage was dipped into the powder at noon in London each day the dog aboard ship yelped.
