Point XXXI

Bird-catchers, may by the help of this prepare such a Birdlime, as will not be altered by Cold or Heat.

If a Spirit be distill’d from Nitre, and Lapis Calaminaris dissolved in it, and the Spirit again drawn off, there will remain a thick and heavy Oyl, with which the Glue for Wood being throughly humected and dissolved, it becometh tenacious and viscous, which will not be dried by the heat of the Sun, but keepeth its unctuosity in all Seasons. N.⁠B. That Spirit of Salt, or Vitriol, also performeth the same thing, if any Glue be dissolved therein.
