[APD] Temperature, Thermometers & Mercury

Reading the thread "De-chloramination" which was moving into methods of temperature measurement prompted me to ask you all to read this article in Discover.com. Its a frightening reality..


While developing my own slide films in the old days I could quite accurately tell temperature by dipping a finger in the water bath. Even now I compare my various tanks with touch and feel temperature assessment.
