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.
