This device is for measuring differences in temperature and was named for British natural philosopher John Leslie. It is considerably more sensitive than a standard thermometer. Physical Description: Wooden pedestal base, ivory-colored face,...
The Kinnersley's Thermometer was an apparatus designed to demonstrate the heating power of an electric spark by showing the expansion of air when an electric spark is passed through it. Physical Description: Glass tube with brass base and top,...
