"Not in the ideal dreams of wild desire
Have I beheld a rapture-wakening form:
My bosom burns with no unhallow'd fire,
Yet is my cheek with rosy blushes warm;
Yet are my eyes with sparkling lustre fill'd;
Yet is my mouth replete with murmuring sound;
Yet are my limbs with inward transport fill'd;
And clad with new-born mightiness around."
Davy also took nitrous oxide to relieve toothache: "The power of the immediate operation of the gas in removing intense physical pain, I had a very good opportunity of ascertaining...In cutting the unlucky teeth called dentes sapientiae, I experienced an extensive inflammation of the gums, accompanied with great pain....On the day when the inflammation was most troublesome, I breathed three large doses of nitrous oxide. The pain always diminished after the first three or four inspirations; the thrilling came on as usual...."
