20Janvier, l869.-Monsieur and Young Friend:
You who know how to enjoy the charms of
meditation, listen to me; let us penetrate to-
gether into this asylum surrounded by silence,
where the soul of Descartes is profoundly occu-
pied with sublime objects, and is plunged in
sweet 1avishments unknown to the vulgar. Be-
hold him, blessed with a contentment such as
kings cannot buy; the august stamp of refec-
tion is on his forehead; the light of thought
ourns in his eyes; his intellect, enlightened by
the purest rays OF human reason, is IN glo-
rous communion with Nature, with God HIM
self. In this moment his eye pierces the highest
heavens; seeks the secret knots, the concealed
principles, the marvellous enchainment of cause
and effect; embraces the universe which is not
more vast than his genius. Let us follow him
inf his laboTs in his meditations; let us examine
them with care. II is a good rule to follow;
and Tor long time have been trying to make
professional study OF his life, and OF the mis-
tory of his philosophy and his other works.
THIS is why have collected everything remark.
able which occurred TO him in the course OF his
career. have a great number of notes on the
subject, which l will communicate to you If you
wish. PASCAL.
NEWTON TO PASCAL.
Monsieur:-Lately the thought occurred to me
to verify a calculation Of which have already
spoken 10 you, which is, to examine according
to VIA line descends body which fails from
an elevation, taking account of the movement
of the earth around its axis, and of which one
OF your notes has given me the idea. As such
q body has the same movement as the place
from which it falls has by the rotation of the
earth, it ought to be considered as being pro-
jected forwards, and at the same time attracted
towards the centre OF the earth. This research,
xuhf fnh hoc Tnt1n tInn wit 10 m
of the moon, has induced me TO resume my
labors. To proceed with security, wished to
establish 30 principle and to make no suppos-
| ton. ] have consulted Nature herself have
| carefully followed her operations and have only
aspired to discover her secrets by experiments
| selected and repeated Firm in my project, l
have resolved to admit no objections against an
evident experiment which have been deduced
| from metaphysical considerations. Such is the
plan of study that have formed, and that
| wish to follow henceforth. If were not afraid
of troubling you, would send you, now as
| formerly, my experiments. | wait for your
reply: l am, sir, your very humble and well
! affectioned ISAAC NEWTON.

| 2 Feyrier 659.-Monsieur:-Th divers notes
| that you have been so kind as to send me,
| tou ching the late M. Descartes have been so
agreeable to me that permit myself to demand
| of you perlnssl on to keep them while longer,
wishing to reread them again, and L pray you,
also, to give me some more information con-
ceInlng this illustrious parsonage, whom, with
| out doubt you have known in private lite, and
| whom you have been so we'll able to appreciate.
| Certes, Descartes is the greatest genius of our
| century, no one can doubt, and, therefore, it is
\ great pleasure for me to know all the details
/ of his existence. write TO you no more to-day,
| Monsieur. wait for reply from you, which
will be agreeable to me, If you will be kind
| enough to tell me more about the late NJ. Des-
cartes, and conceal from me nothing that you
| know. should be glad also to know where
his papers can be found, that am told returned
to France some years ago. l have found here
among the papers Of the Chevalier d'Igby, who
! had several conferences with NJ. Descartes, and
who was among the number OF hlsprncipal
| friends-I have found, l say, certain letters
| extremely curious, which have heightened my
esteem for him. II by chance you know the
letters that the Chevalier d'Igby has written to
M. Descartes, should be much obliged to you
to instruct me concerning them.
I am, sir, and very good counsellor, your
humble servant and friend, ISAAC NEWTON.
To Mons. Pascal.

II Mars, 166l.-I have learned, Monsieur, to
my great displeasure, that you are always sut
fefing. That is without doubt the reason that
for so long a time | have received no letter
from you. Will it be possible Tor me to receive
any more? If your disease is not the cause
which has prevented you from writing to me-
can it be that you have something to to complain
complaint The services that you have rem
dered me are too great to let It be possible thai
| should be guilty of incivility towards you
though possibly by ignorance, certainly not
with intention. l know that you wrote TO mt
that you had abandoned the sciences, to devote
yourself TO other studies, which are probably nc
more connected with nine. If that be the
reason, | regret it; but am not and cannot bt
less all my life your admirer, and your very
humble and Well-affectioned servant,
ISAAC NEWTON.
To Monsieur Pascal.
