lAVINC by reason of the largeness of the pre-
ceding volumes, which contain much more than 1 ex-
pected, some pages to spare, I am well pleased -with
an opportunity of inserting here another extract from,
one of the most ingenious treatises which I believe was
ever wrote upon the subject, Mr. Deutens's u Inquiry
into the Origin of the Discoveries attributed to the Mo-
derns." I am surprised that I never heard of it till
very lately, and 1 have met with exceeding few that
have; although the Latin original (I suppose, for I
have not se-n it) has been published pood part of
twenty years, and the elegant and judicious transla-
tion of it was printed eight or nine years ago. It is
true 1 am hereby convinced of several mistakes which
1 had been in for many years; but I look upon every
such conviction as a valuable acquisition : and I trust
iny heart will always say, both to God and man,
4 What I know not, teach thou me."

THE



AUTHOR'S PREFACE.



.AN the comparison between the moderns and an-
cients, a distinction ought to be made between the
arts and sciences which require long experience and
practice to bring them to perfection, anil those which
depend solely on talent and genius. Without doubt,
the former in so long a series of ages, have been ex-
tended more and more, and brought to a very high de-
gree of perfection by the moderns, who in this respect
surpass the ancients, though the art of printing and
many other discoveries have not a little contributed
to it. We know the astronomers in our days under-
stand much better the nature of the stars, and the whole
planetary system, than Hipparchua, PtoKmy, or any
other of the ancients. But it may be doubted whether
they had gone so far, unaided by telescopes. The
moderns have certainly perfected the art of navigation;
nay, and discovered now worlds ; but yet without the
assistance of the compass, America, in all probability,
Iia'.lstili remained unknown. Likewise by long obser.
yation and experiments often repeated, we have
the arts of botany, anatomy, and chirurgery.






to the degree of perfection we now behold them in.
Many secrets of nature, not to be penetrated in one
age, have been laid open in a succession of many. Mo-
rality itself hath been perfected by the Christian reli-
gion ; philosophy hath assumed a new air ; and the
trifling, childish, and rain cavils of the schools, have
at length been put to flight by the reiterated efforts of
Ramu>, Bacon, Newton, and many others.

I willingly therefore give up to the partizans of the
moderns every advantage I have here enumerated ; but
there is no need on that account to rob the ancients of
the share they have had in promoting all these parts of
knowledge, by the pains they took to beat out for us
the tracks we have pursued. Much less should we as-
sume, as modern discoveries, what the ancients really
invented or illustrated. It also deserves notice, that
the most part of the admirable and useful inventions,
in which our age glories, such as printing, gunpowder,
the compass, telescopes, &c. were not the acquisi-
tions of genius and philosophy, but mere effects of
chance. To place in its true light the share the an.
dents havs in whatever we pretend to know^ and even
in what has been called modern discoveries, is the prin-
cipal aim of my present undertaking.



CHAP. I.

Of the Circulation of the Bhod> and the fallopian
Tubes.



HE medical art affords striking instances of the
injustice done to the ancients in endeavouring to de
prive them of the glory of having made the most im-
portant discoveries in it. I shall produce two or three
manifest proofs of this, and doubt not but the reader
vill perceive not only probable hints, but demonstra-
tive evidence, that the ancients dearly taught what we
ow dispute their having had any kt owLdge of.

2. It is remarkable with rrgard to medicine, that
none of the sciences Footter arrived at perfection ; lor
in the space cf tvto thousand )e*r* ? elapsed since the
time of Hippocrates, there has scarcely been added a
new aphorism to those of that great n:aii. notvvith.
standing all the application of so manj ingenious men
as have situ:*; studied that science.

3. I omit taking notice of some modern atthors,
who have endeavoured to prove that the circulation of
the blood was known to Solomon, that I inaj pass to
the more evident proofs of this discovery, wtiicti Hip-
pocrates furoiaher us with. After exan -ining, thoFC
passages no one will deny but this able physician

what he expresses so cLarly.

4 In truth, it is hard to coi ceive that he knew
of the circulation of the blood 9 whn we hear



him say, < That all the veins communicate one with
the other, and run into one another ; that the veins
-which spread themselves over the whole body, filling
it with spirit, juice, and motion, are al) of them but
branches of one original vein. I protest, I know not,"
says he, u where it begins or where it ends, for in a
circle there is neither beginning nor ending.". A little
further he says, u that the heart is the source of the
arteries, which carry blood into all parts of the body,
communicating to them life ani heat ;" he adds, u that
they are the rivulets which cherish the human body,
and convey life to every part of man." In another
part, he says, u that the heart and veins arc always
in motion." He compares the course of rivers, which
return to their sources in an unaccountable and ex-
traordinary manner, to the circulation of the blood*
In apoplexies and such like disorders, which he as-
cribes to obstructions in the veins, he prescribes bleetU
ing, in order to procure a free motion to the blood
and spirits. He says al>o, '* that when the bile en-
tors into the blood, it breaks its consistence, and dis-
orders Us regular course : he compares its admirable
mechanism to clows of thread, whose filaments overlap
each other ;" and says, u that in the body it performs
just such a circ -it, alvvays terminating where it began.";

5. The next to Hippocrates is Plato, who speaks
with clearness of the circulation of the blood; u for
from the heart,'* he says, u spring the veins and.
blood, which with rapid ty carries itself into ail parts) 1 '
adding, that when the blood thickens, it flows with
more difficulty through the veins. Aristotle too re.
gards the heart as the origin and fountain of the veins
and blood. He says, u that from the heart there arise
two veins, one on the right and the other on the left
side; and lu> was the first who called this aorla.'* He
held that the arteries had a, communication with the
veins, and that they were intimately connected tc-
gether.

a 3



6. Julius Pollux, in his Onomasticon, describing
all the parts of the body, and their uses*, among other
thrttgs says, in speaking of the arteries, " that they are
the passages and canals of the spirits, as the veins are
of the blood ;" and in speaking of the heart, he says,
u that it hath two cavities, the one of which commu.*
nicatcs v, ith the arteries, the other with the veins. 1 '
Apulcius in explaining the doctrine of Plato, speaks
likewise of the circulation of the blood, and in a few
%vords describes it as clearly as any of the moderns. It
is true, he does not expressly mention that the blood
flows from the heart through the arteries, but on its
leaving the heart, he supposes its course along the
Jungs, to spread itself afterwards into all parts of the
body.

7. Nemesius, bishop of Emissa, who may be ac-
counted among the ancients, having lived in the fourth
century, has a very clear passage to this purpose,
wherein he says, <fi that the motion of the pulse owes
its origin to the heart; and particularly to the left ven<*
tricle of that viscus. The cordiac artery expands and
contracts itself with very much force^ but always with
great regularity and harmony of motion, In its ex-
pansion it draws in the most subtle parts of the blood .
from the adjoining veins, and of that blood forms the
aliment of the vital spirits ; and in its contraction ex-
hales all the fumes brought into it by secret passages
from all parts of the body*"

8. It appears from what we have said, that the cir.
dilation of the blood was known to the ancients,
thoti.;li they did not expatiate upon it : and what re-
duce;- to a very small degree the honour that Hervey
can claim in making that discovery, is that Servetus
had treated t it very distinctly before him, in the fifth-
part of his book De Ghruiianismi Restifutione ; a
work so very scarce, that there are but tew who can,.
boast of having seen it in print, Mr. Wotton, in hi?



Reflections upon the Ancients and Moderns, cites this
passage of Servetus, in which he distinguishes three
sorts of spirits of the human body, and says, " that
blood, which he calls a vital spirit, is dispersed through
the body by the anastomosis, or mutual insertion of
two vessels, at therr extremities, into one another."
Where it deserves observation, that Servetus is the first
who employed that term to express the communication
between the veins and arteries, He makes the u ex-
panded air in the lungs contribute to the formation of
blood, which cornes to them from the right ventricle
of the heart by the canal of the pulmonary artery."
He says, " that the blojd is there refined and perfect-
ed by the action of the air, which subtilizes it, and
blends itself with that vital spirit, which the expanded
heart then receives as a fluid proper to carry life every
-where." He maintains that this conveyance and man-
ner of preparing the blood in the lungs, is evident from
the junction of the veins with the? arteri -s in this viscus.-
And he concludes with saying, u th/it 'he hra>t having
received the blood thus prepared by the 1 ngs, semis
it forth again by the artery of its left ventricle, ca led
the aorta, which disfributes it into ill parts of the
bo.ly." Andreas Cesalpinus, wao i*ved Hkew;be ia
the sixteenth century, hai-'i tvvo passages which com-
pletely contain all that we know about the circulation
or the blood. He explains at lenth, 4i how the blood
