A Warm Bolus
Take running Mercury well cleansed 1 dram; grind it in a glass Mortar, with brown Sugar, 2 drams; 'till its Particles are so finely divided as to be invisible; towards the last dropping in 2 drops of Oil of sweet Almonds, to which add powdered Scammony, from 4 grains to 10; and with Syrup of Succory with Rhubarb, reduce it to a Bolus.
It looks like a most noble Medicine: But I'll ingenuously confess, I never prescib'd it my self, nor knew it prescrib'd by any other. 'Twas communicated to me, and I communicate it again.
