J 3\(aturall History: 
I forwards. I.conceiue alfo, that the quickd Loofe of that Motion, preueti -1 
tech the Reft flame of the Body below • And Priority ofthe Force (alwaies) : 
is of great Efficacy • As appeareth in infinite Infiancef. 
T ickling is moftin the Soles of the Feet, and vnder the Ame-Holes]\ 
and on the Sides . The Caufe is, the Tbimejje of the skinne in thofe i 
Parts y Ioyned with the Rareneffe of being touched there. For all Tick¬ 
ings light Motion of the Spirits, which the ThinneJJc of the Skin, and 
Suddennejfe, and RareneJJe ol Touch , doe further: For we fee, a Feather, or 
a Ru(b drawnealong the Lip, or Cheeke, doth tickle- Whereas a Thing 
: more Obtufe, or a Touch more Hard, doth not. And for Suddennejje • We 
j fee no Man can tickle himfelfe: W e fee alfo, that rhe Pflme of the 'Hand, 
though it hath as Ihin a Skirt, as the other Parts Mentioned, yet is not 
Ticklifh, becaufeitis accuftomed to be Touched. Tickling allb caufeth 
Laughter. The Caufe may be, the Emiflion of the Spirits, and fo ofthe 
Breath, by a F li ght from Titillation ; For vpon Tic fling, we fee there is euer 
a Starting, or Shrinking away of the Part, to auoid it; And we fee alfo, 
that if you Tickle the Nojlhritis , with a Feather, or Straw, itprocureth 
Sneezing - 3 Which is a Sudden Emiflion of the Spirits , that doe like- 
wife expell the Moiflare . And Tickling is euer Painfull, and not well, 
endured. 
I T is ftrange, that the Ritter of Nilus i Oucr-flowing as it doth, the 
Country of *&g}pt, there fhould be neuerthelelfe little or no Rome in 
that Country. The Cauje mu ft be, Either in the Nature of the water ; Or 
in the Nature of the Aire - Or of Both. In the water, it may be aferibed, 
either vnto the Long Race of the water , For swift Running waters va¬ 
pour not fo much as Standing waters - Or elfe to the Comottion of the 
water-, For waters well ConcoHed vapour not fo much as waters Raw - No 
more than Waters vpon the Fire doe vapour fo much, after fome time of 
Boyling, as at the firft. And it is true, that the Water of Nilm is Tweeter 
than other Waters in Tafte; And it is excellent Good for the Stone, and 
Hypochondrtacali Melancholy - Which fheweth it is Lenejyin^ : And it run¬ 
neth thorow a Countrey of a Hot Climate, and flat, withourShadc, either 
I of Woods, or Hills ; Whereby the Sttnne muft needs haiie great Power 
| t0 ConcoB it. As for the Aire, (from whence I conceiue this Want of 
Showers commeth chiefly 5 ) The Caufe muft be, for that the Aire is, of 
it felfe, "Thin and Thirfly- And as foone as euer it getceth any Moifluraj 
from the Water , it imbibeth, and diflipateth it, in the whole body of the 
Aire • And fuffereth it not to remaine in Vapour-, Wherebv it might 
breed Raine. 
I T hath beene touched in the Title of Percolations , (Namely fuch as 
are Inwards,) that the whites of Egs, and Milke , doe clarifie ; And it is 
certaine, that in^Fgypt, they prepare and clarifie the water of Nile , by 
putting it into great lanes of Stone, and Stirring it about with a few
