what lay before this frefhiy admitted iiutritious Juice, • ^ ;7:rd e 
extremities of tbefe Veffels in the furface of the Body, ouc of 
which, being continually open, they muflj pals now plentifully, and 
thence he accounts for SanUorms\ Terfpiratio major at this rime, 
which done, 'tis obvious it cannot proceed fo plentifully all the day, 
tho ftill the protrufion being inceffant, fome muft go forth. 
But becaulehe fuppofes, that both the matter of this Perfpiraijon 
and'Sweit pafs forth at the fame Vores in tlie Skin, he endeavours 
to folve this dbubt, by confidering the Glandules ( which make up 
the Skin ) either as made up of thefe fibres^ q>xz% Secretory Organs^ 
and fuppofes, f/;y?, That what the Fibres, as ftich, contain, m.uft 
by the before-meniioned protrufion be continually, carried on to 
their extremities, which lye every where within the cavity off thefe 
Glandules, as well as at their furface, and fo pafs of/ into thofe 
cavities ^ mx feconily, in the other confideration thefe Glandules- 
having a Secretory duct^ which all along makes their cavity, the 
fuperfluousor much exagitated ferofities of the Blood niaice their 
way into the Roots of it. and fo muft be continually carried on the 
fame way that the otiier Liquor goes. 
But fince he believes his Hypothejis Nezv, he conceives itrequifite 
to elucidate fome things not before fufficiently explained, and there- 
fore endeavours to examine the Source and Nature of this perlpirable 
matter, and to affign briefly the advantages of infenfible Peripiration, ' 
and the hurt of immoderate Sweats. 
Rethinks therefore that the matter of this Perfpiration proceeds 
imm.ediately from ;r/)/T^' S/'r/^gj", xhQ Nutritious Juice^ B;ooJ and 
folid Varts, And though he takes the firft to afibrd the far grc-dteU part 
of this matter, yet he denies not that fome part of it may be fup- 
ply'd by the other two. And firft. The B/^^?^ abounding with great, 
numbers of very fubtile particles, and all parts of tlie Body being 
porous, 'tis very likely that fome will iecede at them, but it being 
both very Heterogeneous, and blended by the violent circulitory 
morion, and withal much of it fitted to pafs oft^ ar tiic Scceiory 
DuQs Nature has framed for that purpofe, 'tis but Little ol" it that 
can pafs this way. Then as to the folid Farts, Thefe i c'^ j firft 
made of the Fluids, muft as they decay return into tbem v rmd 
fo pafs off the fame way, that the fuperiiuities of the NiKriiioiis 
Juice does. But then as to the Nutri/iojs fjiceit. M\\ which he 
concei-'^^es is carry'd to all parts by the ribies, l-e conceive.5 diis fap-
