B EaJls arc more Hairy than Men ^ and Swage Men more thanciuill^ 
And the Plumage of Birds exceedeth the Pilofity or Beafts. The Caufe 
of the Smoothnefie in Men, is not any Abundance of Han and Moifture, 
though that indeed caufeth Pilofity • But there is require to Pilofity, not 
fo much Heat and Moijlure, as Excrement itious Heat and Moijlure : (For 
whatfoeuer alfimilateth, goeth not into the Haire ■) And Excrementi- 
tious Moijlure aboundeth molt in Beafts, and Men that are more Sauage. 
Much the fame Rcafbnis there of the Plumage of Birds-, For Birds aifi- 
milate lefle, and excerne more than Beefs : For their Excrements are 
euer liquid, and their Plefh (generally) more dry : Befides, they hane 
not Inftruments for rrine ; Andfo all the Excrememitiom Moifluregoeth 
into the Feathers : And therefore it is ho Maruell, though Birds bee 
commonly better Meat than Beafts , becaufe their Flefb doth aflimilate 
more finely, and fecerneth more fubtilly* Againe, the Head of Man hath 
Haire vpon the firft Birth, which no other Part of the Body hath. The 
Caufe may be Want of Perforation : For much of the Matter of Haire, in 
the other Parts of the Body, goeth forth by Infennble Perfpiration-, And 
befides, the SkuH being of a more folid Subftancc, nourifheth andaf- 
fimilateth leffe, and excerneth more: Andfo likewife doth the Chtnne-, 
We fee alfo that/toe comraeth not vpon the Palmes of the Hands, nor 
Soales of the Feet ; Which are Parts more Perftirahle. And Children 
likewife are not Hairy, for that their Skins are more Perjjirable. 
B irds are of Swifter Motion than Beafls : For the Flight of many Birds 
is Swifter, than the race of any Beafls. Th e Caufe is, for that the Spi¬ 
rits in Birds , are in greater Proportion, in comparifon of the Bulke of 
their Body, than in Beafts : For as for the Rcafon that fome giue, that 
they are partly Carried, whereas Beafts goe, that is Nothing; For by 
that Reafon Swimming fhould be iwifter, than Running : And that 
Kinde of Carriage alfo, is not without Labour of the wing. 
T He Sea is clearer , when the North-wind bloweth, than when the! 
South-wind. The Caufe is, for that Salt-water hath a little OvlinejfeX 
in the Surface thereof-. As appeareth in very Hotdaies: And againe, tor ; 
that the Sou theme' Wind relaxeth the Water fomewhat; As no water I 
Boy ling is fo Cleere as Cold Water. 
F ire burneth wood, making it firft Luminous . Then Blache and Briu 
tie-, And laftly, Broken and Incinerate: Scalding Water doth none of] 
thefe. The Caufeis, for that by Fire,the Spirit oh the Body is fir ft Refined , I 
and then Emitted, Whereof the Re fining,ox Attenuation caufeth the Light j 
And the Emiffion , firft the Fragility, and after the Dijj'oluticn into Afhis ; | 
Neither doth any other Body enter: But in water the Spirit of the Body j 
is not Refined fo much ; And befides Part of the water ent.eth - Which 
doth incrcafe the Spirit, and in a degree extinguifh it: Therefore we fee j 
that'
