the zero point is determined by placing the thermometer in brine: he used a mixture of ice, water, and ammonium chloride, a salt, at a 1:1:1 ratio. This is a frigorific mixture which stabilizes its temperature automatically: that stable temperature was defined as 0 °F (−17.78 °C). The second point, at 32 degrees, was a mixture of ice and water without the ammonium chloride at a 1:1 ratio.
The third point, 96 degrees, was approximately the human body temperature, then called "blood-heat"
I knew something had to do with human blood. I think my teacher professor must have been blabbering or I was half asleep. Woops.
