282 LECTURE VI. 



through which gaseous and watery fluids 

 containing some mucilaginous and saline 

 substances are eliminated from the circu- 

 lating system. We see the sweat escaping 

 from regular pores, and not irregularly 

 transuding, as if it passed through in- 

 terstices in the cuticle. Substances rubbed 

 on the skin gain entrance into the absorb- 

 ing vessels, and it is very improbable that 

 they pass through the compact cuticle, in 

 order to arrive at their orifices. We see 

 the ducts of the oil-bags terminatino; on 

 the surface of the cuticle. It seems here 

 right to observe, that myriads of oil-bags 

 are disseminated throughout the skin, from 

 which ducts proceed to the surface of the 

 cuticle to anoint it every where ; and that 

 it is most liberally oiled in parts subject to 

 the greatest friction or evaporation. If we 

 throw water upon our arms, we find it re- 

 pelled in globules, as from a greased] sur- 

 face. Every hair also receives a small co- 

 vering from the cuticle, as it penetrates 

 that substance ; which covering so tena- 

 ciously adheres to it, that in taking off the 

 cuticle, when the skin is slightly putrid,
