label: Description
content: John Rutherford, a Scottish country doctor, devised this form in 1790. Green stated in 1900 that it was "the only one in general use." It has a black index inside the tube. "On a decrease of temperature the alcohol recedes, taking with it the glass index; on an increase of temperature the alcohol alone ascends the tube, leaving the end of the index farthest from the bulb indicating the minimum temperature."
