By the Dry Rod F the Water is Depressed (Coition)
Tuesday, April 5th, 2011Rods in a water basin attract or repulse water. When the rod has a wet end, it attracts water, when the rod is dry, it repulses water. Here rod F is dry and depresses the water nearby. [ZB Magnet 2] William Gilbert, De Magnete (London: Petrus Short, 1600), Zentralbibliothek Zürich, Alte Drucke und Rara, XVI.28, p. 58.
