86 Polypes, how to dry them. 



fpeedily, leaving the Polype flicking to the 

 Talc in the Manner it was difpofed. 



The chief Difficulty now is over, but fomc 

 Caution is flill needful to fccure it fafely in a 

 Slider : for if another Talc be laid upon it in 

 the common Way, all our Labour will be 

 rendered fruitlefs by its being broke and 

 fpoiled. To prevent this Misfortune, as 

 foon as the Talc v/hereon the Polype (licks is 

 let down into the Hole of a Slider, I cut three 

 little flat Pieces of Cork, about the Bignefs 

 of Pins Heads and the Depth of the PolypCy 

 and gum them, in a triangular Pofition, part- 

 ly on the Edges of the faidTalc as it lies in the 

 Hole, and partly to the Ivory Sides of the 

 Hole itfelf^ by which Means, the upper 

 Talc being kept from being able to prefs upon 

 the Polype, it may be put on, and fixed 

 down with a Bix.fs Ring, v/ithout any Fear 

 of hurting it. 



If you intend to dry a Polype in its con- 

 traded State, it may be put diredly into the 

 Spirits without uflng any Le?7s : but if you 

 defire it extended, you'll liiid the Lens quite 

 needful. 



Vinegar, Water wherein Salt is diflblved, 

 or Spirit of Wine kills a Polype immediate- 

 ly. But Spirit of Wine is flttefl: for this 

 Purpofe, as it gives a greater Firmnefs to the 

 Parts, drys away from the Talc fooneft, and 

 leaves no Soil or Smear behind it as the others 



do.
