JUNE 18
I advise you: (1) be electrified (if need be) eight or ten times. (2) keep your body always open, and that by food (as baked, boiled or roasted apples) rather than by physic. (3) Wash your head every morning with cold water, and rub it well with coarse hempen towel. (4) I advise you and Sister Taylor to breakfast three or four weeks on nettle tea. Then you will find preaching, especially in the morning, one of the noblest medicines in the world.
to Thomas Taylor, 1775
O John, pray for an advisable and teachable temper.
Letter, 28th July, 1775
