A Mechanifm analogous to this is prepared for Aquatics^ by a kind of mineral hzxdcx: Scales^ to defend the tender Fibres from the Injury of the denfer and heavier Flnid of Watery their Element. 12. The fame analogous Contrivance is provided for the Covering of the internal Su¬ perficies of the Bowels of Animals, (and befides that, every original linear Solid has a Cafe or Sheath) where an infinite Number of Glands^ by the Force of the animal Fundions, are con¬ tinually fipewing out a more vifeous or crafler Fluid, which becomes a Slime or Mucus to fheath and defend them from the internal Aura, and their Frictions upon one another, and by its Lubricity to keep them (the Membranes') moilt and elaflic. And as this internal Aura is more delicate and lefs deleterious, than the external Element, this Cuticle oiMucus is foft- cr and thinner; but there is an abfolute Necel- iity for fuch a Mucus and Cuticle, to moiften and Iheath their Delicacy and Senfibilitj, and therefore this Cutis is thinner ; For one fo coarfe$
