'Emetics.--For want of proper physic, drink a charge of gunpowder in a tumblerful of warm water of soap-suds, and tickle the throat.'
'Snake-bites.--Tie a string tight above the part, suck the wound, and caustic it as soon as you can. Or, for want of caustic, explode gunpowder in the wound.' - Art of Travel, 1872
