To shew the cognation that even gross and empyreumatical oiles may have with pure {spirit of wine} Ialtered from 'm' made the following experiment's' at end of word deleted Haveing caus'd some Guajacum to be distill'd per se in a Retort (the common way) we tooke the oil after it had been purified by Rectification, and put to it in a phial a convenient quantity of highly rectified {spirit of wine}, and then haveing well shaken these liquors together they seem'd to be thoroughly mix'd after a differing manner from that of {spirit of wine} and oil of Turpentine or oil of Amber &c when these are shaken together, and thô we kept this very black and dark mixture for several days in a quiet place, yet we perceived not that the liquors did separate from one an other, as it is wont to happen in an hower or two or less when {spirit of wine} is confounded with oil of Turpentine or Petrolium &c.

For a Pendulum to vibrate 1/2 seconds a quarter of the Length namly nine inches 15/16 is to be taken.
