Walrus tusk thermometer with reaumur and farenheight scale, ( the reaumur scale was adopted in France and most of Europe and April 1st 1794 the French government instituted the centigrade scale as part of the new, decimal, metric system, thus doing away with the reaumur scale.) 15.5"H mounted on a carved matching ivory base. Lacking mercury tube, small stress cracks from age, ivory turning yellow from age, a nice early piece. Private collection Clarkston Michigan.
