- Mercury-in-glass centigrade thermometer with a range from -20 to +110 degrees. Inscriptions on the white back read “TOTAL IMMERSION” and “ARTHUR H. THOMAS PHILADA USA” and “No. 1” and “PTR 995 1938.” This was presumably made in Germany and calibrated at the Physikalisch-Technische Reichsanstalt (Imperial Physical Technical Institute).
