Mercury-in-glass thermometer with a fairly large cylindrical bulb that could probably float in water. An auxiliary glass tube attached to the stem holds a hand-written piece of paper marked “Thermometre Selon Fahrenheit et Decimal par Pixii rue du Jardinet N° 2 A Paris.” This paper also carries two parallel scales. One extends from -30 to +127 graduated every degree, with indications for “Glace Tempere” at zero and “Eau Bte” at 100. The other extends from -22 to +260, graduated every 2 degrees.
This thermometer was made between 1818 and 1838 when Pixii worked at rue du Jardinet N° 2. It may have belonged to the American scientist, John William Draper.
