XXXI.

_MADAM,_

Your _Author_, in opposition to the Schools, endeavouring to prove

that there are no humors in an animal body, except blood, proves

many humors in himself. But I can see no reason, why Nature should

not make several humors, as well as several Elements, Vegetables,

Minerals, Animals, and other Creatures; and that in several parts of

the body, and many several ways; for to mention but one sort of other

Creatures, _viz._ Vegetables, they are, as we see, not onely produced

many several ways, but in many several grounds; either by sowing,

setting, or grafting, either in clayie, limy, sandy, chalky, dry, or

wet grounds: And why may not several humors be produced as well of

other Creatures and parts, as others are produced of them? for all

parts of Nature are produced one from another, as being all of one

and the same Matter, onely the variation of corporeal motions makes

all the difference and variety between them, which variety of motions

is impossible to be known by any particular Creature; for Nature can

do more then any Creature can conceive. Truly, _Madam_, I should not

be of such a mind, as to oppose the Schools herein so eagerly as your

_Author_ doth; but artificial actions make men to have erroneous

opinions of the actions of Nature, judging them all according to the

rule and measure of Art, when as Art oft deludes men under the cover

of truth, and makes them many times believe falshood for truth; for

Nature is pleased with variety, and so doth make numerous absurdities,

doubts, opinions, disputations, objections, and the like. Moreover,

your _Author_ is as much against the radical moisture, as he is against

the four humors; saying, that according to this opinion of the Schools,

a fat belly, through much grease affording more fuel to the radical

moisture, must of necessity live longer. But this, in my opinion,

is onely a wilful mistake; for I am confident, that the Schools do

not understand radical moisture to be gross, fat radical oyl, but a

thin oylie substance. Neither do they believe radical heat to be a

burning, fiery and consuming heat, but such a degree of natural heat,

as is comfortable, nourishing, refreshing, and proper for the life

of the animal Creature: Wherefore radical heat and moisture doth not

onely consist in the Grease of the body; for a lean body may have as

much, and some of them more Radical moisture, then fat bodies. But

your _Author_ instead of this radical moisture, makes a nourishable

moisture, onely, as I suppose, out of a mind to contradict the

Schools; when as I do not perceive, that the Schools mean by Radical

moisture, any other then a nourishable moisture, and therefore this

distinction is needless. Lastly, he condemns the Schools, for making

an affinity betwixt the bowels and the brain. But he might as will

condemn Politicians, for saying there is an affinity betwixt Governors

and Subjects, or betwixt command and obedience; but as the actions of

Particulars, even from the meanest in a Commonwealth, may chance to

make a Publick disturbance, so likewise in the Common-wealth of the

body, one single action in a particular part may cause a disturbance

of the whole Body, nay, a total ruine and dissolution of the composed;

which dissolution is called Death; and yet these causes are neither

Light, nor Blas, nor Gas, no more then men are shining Suns, or flaming

Torches, or blazing Meteors, or azure Skies. Wherefore leaving your

_Author_ to his contradicting humor, I rest,

Madam,

_Your faithful Friend_

_and Servant._
