About this source

What it is

This is a scientific paper written in Latin by Daniel Gabriel Fahrenheit and published in 1724 in the Philosophical Transactions of the Royal Society in London, volume 33. It reports experiments on the boiling points of different liquids.

Why it matters

Fahrenheit used standardized thermometers that he built himself to compare liquids precisely. This paper shows how careful, repeatable measurement became central to experimental science in the 1700s, and how Fahrenheit's instruments let him test ideas first raised by other scientists he had read about.

Look closer

  • Why would a scientist write in Latin instead of his native language?
  • What does it tell you that Fahrenheit needed to build his own instruments before he could do this experiment?
  • What questions might this paper leave unanswered about how the experiments were actually performed?
