Heads of Old Garlick 32 fe were dryed in a Furnace 
and burnt, from the Afties there was hardly any Salt to 
be gathered. 
Thirty Pounds of Wheat-Flower burnt in a Furnace 
with a little Sulphur, and burnt anew in a Potter's Oven, 
give 8 5 of very black Afhes, the which being Baked 
again for Fj'ghc Days continually in a Br ck Furnace, af- 
ter the Lye was made, there could not be a Grain of 
Sale drawn. The like happened in 10 5 of Afhcs drawn 
from a Stare and a half of Bran, burnt firfl: in tl^e Fur- 
nace with Sulphur, and afterwards baked in a Potters 
Oven, and in cije of Bricks. 
16. All the Salts whatever drawn frcm the Afl^es of 
Vegetables, takefj by the Mouth, fays he, have a Pur- 
ging Faculty, and a great Meafure more than u har by 
lome is believed in common Silt, which taken by the 
Mouth has little or none at all, or if it have any btcwixt 
that ofis common Salt and Vegetables, the Proportion is 
but as Two to Eight. 
17. This Solutive Faculty is of equal Energy in all the 
Salts in fuch Manner that the Salt of Su mack, Pedes of 
Pomgranates, Mirtle Berries, or Maftick Purges as 
much as the Salt of Rubarb, Sena Turbith,^ Mechoacan, 
and all other like purgative Drugs. 
18. The Dofe to be u(ed is the fame in all the Salf?, 
to wit, from Two Drachms and an half to half an Ounce, 
diflolved in Six Ounces of common Water ; and Broth 
be has obferved by infinite Experiments, that half an 
Ounce ufes to Purge Three Pounds and a half, or Four, 
or thereabouts, of Matter more or iefs, according to the 
Complexions, and according to the Fulnefsof the Bodies. 
19. In Purging he has found no ditlerence betwixt 
thefe Salts that have fharp Points, and thofe that are ob- 
tufe and blunt or cubical; he has made P^oof very often in 
divers Perfons, caufing the like cubical Stones of Cucum- 
bers
