Mercury-in-glass thermometer designed for diagnostic purposes. It has a spherical bulb. The stem is bent, above the bulb, so as to hold a rolled paper securely in place. This paper carries a scale reading from 19 to 46 degrees Centigrade. The section from 32 to 43 degrees (that is, the range of body temperature) is graduated in tenths. The scale is marked “M. Leyser, Jnsp. a.d. Univ. Leipzig / 30080” and “Celsius.” The whole is enclosed in an outer glass tube.
