III. I confider’d the Difeafes in Human Bodies, which 
thefe Waters were prefcrib’d, by Phyficians, to cure 5 
that they were often fuch as proceeded from Sharp, 
Acid, or Acrimonious Caufes, as Cardialgi £ or Heart- 
burnings, fower Vomitings, Corrofive Diarrh£a > s , Golicks 
from Scurvies and Stranguries 3 and that for thefe Di- 
ftempers fwcetning and Alkalifate Remedies are made ufe

IV. I confider thefe Waters as containing in them 
the Properties of Iron 5 and I find by experience, that 
it is moft oppofite to Acids, being one of their great

will tafte fweetifh, and is by Chy miffs call’d Saccharum

2. Steel beaten to a fine Powder is, without any far-

Stomachic Difeafes, as in the Green-Sicknefs, Hyi ochon-

V. I confider’d Milk to be a very proper and obvious 
Subjed to bring this Controverfy to a plain and unque- 
ftionable decifion. 1 made this Experiment with all pof-
