Bath Thermometer

<< >>
Bathing, whether for cleanliness or health, was not a common practice in Colonial America, or even Great Britain, and only became so over time. This bath thermometer indicates this changing practice. It was probably owned by John William Draper (1811-1882), an American scientist with wide-ranging interests and accomplishments and who kept in touch with friends and colleagues abroad.
This is a simple mercury-in-glass thermometer designed for determining when bath water is at a healthy temperture. The scale extends from 0 to 130 degrees, and is marked "Dr. FORBES SPECIFICATIONS" as well as "FREEZING"; "COLD BATH"; "COOL"; "TEM."; "TEPID"; "WARM"; and "HOT." The reference is to John Forbes, a Scottish physician who recommended therapeutic bathing.
