    THEORY OF THE GENUINE HYDROMETER, Farther Illustrated. i- s 1 find by Experience the Lines of the ^ a ^ Hydrometric Scale are not fo generally and eafllY uoderftood as I expended, and $Ksk could wifh them to be, and in Confe- quence thereof, the Ufe of this new and genuine Hy¬ drometer is not fo intelligible, and therefore not fo much encouraged as it really deferves 5 I have thought it neceflary to give a further Illuftration of the Nature and Ufe of this Infixument, by fuch Draughts and Re- prefentations, as, I hope, will render it a Matter of the utmoft Facility. And that nO Difficulty or Defici¬ ency may poflibly remain, or be objected, 1 have added a Table, to {hew by Infpedtion the Quantity or Mea- fiire of Alchohol or Water that is requilite to be added to any Compound, to make it exaddly either Real or Merchantable Proof.
