Quotes by others about Guillaume Amontons (3)
When a [mercury] thermometer was made (perhaps imperfect in many ways) the result answered to my prayer; and with great pleasure of mind I observed the truth [that water boils at a fixed degree of heat].
I read that the celebrated Amontons, using a thermometer of his own invention, had discovered that water boils at a fixed degree of heat. I was at once inflamed with a great desire to make for myself a thermometer of the same sort, so that I might with my own eyes perceive this beautiful phenomenon of nature.
It then came into my mind what that most careful observer of natural phenomena [Amontons] had written about the correction of the barometer; for he had observed that the height of the column of mercury in the barometer was a little (though sensibly enough) altered by the varying temperature of the mercury. From this I gathered that a thermometer might be perhaps constructed with mercury.
