human thermo-dynamics

In the history of human thermodynamics, the first use of the term human thermo-dynamics, as a self-standing subject, is found in the 1893 Transactions of the Manchester Association of Engineers, with the hyphenated version listed in the index, referring to page 176 of the book. The page refers to chapter five, titled "Human Thermodynamics", with the subsections as indicated below: [1]

Human Thermodynamics
(a) vital heat of the body
(b) experiments on the amount of heat developed by human beings when in action
(c) measurement of oxygen inhaled
(d) respiration shown to be the principle source of heat.

The seven-page chapter presented the results of French physicist Gustave-Adolphe Hirn’s 1856 experiments in the determination of the mechanical equivalent of heat of a human being in working action. The term thermo-dynamics, to note, was coined in 1849 and stayed in use well into the 1920s, when thereafter the subject lost the hyphen.
