IT has been long known that Sir Isaac Newton left, at his
death, a large mass of papers, consisting partly of copies of
his works written out or corrected for the press, partly of notes
relating to the various subjects in which he was interested,
and of an extensive correspondence with English and Foreign
mathematicians. These came immediately on his death into
the possession of Mr Conduitt, who married Catharine Barton,
Newton's favourite and accomplished niece. By the marriage
of their only child to the first Lord Lymington, they passed into
the hands of the first Lord Lymington, and we find them in
October 1751 in the hands of Mr Saunderson of Sheer Lane, for
Lord Lymington 1 . Since that time they have remained in the
possession of the Portsmouth family.
Several years ago the present Earl of Portsmouth expressed
a wish to present to the University all that portion of the papers
and correspondence which related to science, as he felt that
these would find a more appropriate home in the Library of
Newton's own University than in that of a private individual.
Lord Portsmouth entrusted the whole collection of papers to
the University, and the present syndicate was appointed to
examine, classify, and divide them. This has proved a lengthy
and laborious business, as many of the papers were found to be
in great confusion mathematical notes being often inserted in
the middle of theological treatises, and even numbered leaves of
MSS. having got out of order. Moreover a large portion of the
collection has been grievously damaged by fire and damp. The
1 See Stukeley's Memoirs (Surt. Soc., 1887) iii. p. 15.
correspondence, however, is in a very fair condition throughout,
and had been arranged in an orderly manner.
On receiving a preliminary report on the contents of the
collection, Lord Portsmouth expressed a wish that the papers
relating to Theology, Chronology, History, and Alchemy, should
be returned to him at Hurstbourne, where they would be care-
fully preserved. On account of his connection with the Newton
family, Lord Portsmouth also naturally wished to have returned
to him all the papers relating to private, personal, and family
matters. These, however, are comparatively few, and not of
much interest, with the exception of a short note from Newton's
mother, written to him when a boy at College.
Although till the present time the papers have never been
thoroughly examined, they have been looked at and partially
used by various persons since Newton's death. When that
occurred (in 1727) Dr Pellett was appointed by the executors to
examine them and to select such as he deemed fit for publica-
tion. A rough catalogue of the papers is appended to a bond
given by Mr Conduitt to the administrators of Newton's estate,
in which he binds himself to account for any profit he may
make by their publication. This list, with some remarks of
Dr Pellett, will be found in Hutton's Mathematical Dictionary.
All which Dr Pellett deemed fit to be printed were An Abstract
of the Chronology in 12 half-sheets folio, and The Chronology of
Ancient Kingdoms Amended in 92 half-sheets folio; and these
were printed in 1728 under the care of Mr Conduitt.
The whole collection was inspected by Dr Horsley, who
edited in 1779 the well-known edition of Newton's works in five
quarto volumes. He left a few unimportant remarks on some
of the papers, but he made no use of them in his edition.
It was again placed in the hands of Sir David Brewster, for
his second and elaborate life of Newton in 1855; he made some
use of the scattered mathematical notes and papers, and printed
a considerable portion of the correspondence.
The character of the collection will be made clear by the
catalogue which is now put forth. It divides itself (excluding
the correspondence) into the heads of Mathematics, Chemistry
and Alchemy, Chronology, History, and Theology. Many of
the Mathematical papers contain Newton's preparations for the
Principia, and notes which spring out of questions that were
started by his correspondents. It must be recollected that
Newton practically gave up his mathematical studies after 1696,
even the superintendence of the second edition of the Principia
being given to Cotes, and thus that after this date there is little
of value in these subjects ; and as most of what is contained in
them, especially all that relates to the revision of the Principia,
has been published, there is little to be found beyond what has
The case is different, however, with respect to the papers
referring to three subjects, viz. 1st, the Lunar Theory, 2nd, the
Theory of Atmospheric Refraction, and 3rd, the Determination
of the Form of the Solid of Least Resistance.
It is expressly stated by Newton himself that the Lunar
Theory as given in his Principia is a mere specimen or fragment
of the subject, intended to show how some of the more prominent
lunar inequalities could be traced to the disturbing action of
the Sun, and how their amounts could be calculated approxi-
mately by theory.
The only part which is developed with any fulness of detail
is that relating to the inequality called the variation, and also
that which treats of the motion of the node and the change of
inclination of the orbit to the ecliptic.
In a short scholium given in the first edition of the Principia,
Newton mentions that by similar computations he has found
the motion of the moon's apogee, and he states some of the
numerical results which he has obtained, but he does not give
the calculations themselves, as he considers them too complicated
and not sufficiently accurate.
In the second edition this short scholium is replaced by a
long one, in which Newton states many of the principal results
of the Lunar Theory, partly as found from theory alone and partly
as deduced by combining his theory with observation ; but he
confines himself to results alone, and does not give the method
by which these results have been obtained. Unfortunately also,
the statement given in the first edition, as to the result which
he had found by theory for the motion of the moon's apogee, is
omitted in the new scholium.
It is interesting to find among the papers on the Lunar
Theory a good many containing Newton's calculations relating
to the inequalities which are described in the above scholium.
These papers are unfortunately very imperfect, and they have
greatly suffered from fire and damp, but there is enough re-
maining to give a general idea of Newton's mode of proceeding.
The most interesting of these papers relate to the motion of the
moon's apogee. Two lemmas are first established which give
the motion of the apogee in an elliptic orbit of very small
eccentricity due to given small disturbing forces acting, (1) in
the direction of the radius vector, and (2) in the direction
perpendicular to it.
These lemmas are carefully written out, as if in preparation
for the press, and they were probably at first intended to form
part of the Principia.
Next follows the application of the lemmas to the particular
case of the Moon, in which the supposition that the disturbances
are represented by changes in the elements of a purely elliptic
orbit of small eccentricity would lead to practical inconvenience,
and consequently Newton is led to modify that supposition.
In the Principia he shows that if the moon's orbit be supposed
to have no independent eccentricity, its form will be approxi-
mately an oval with the earth in the centre, the smaller axis
being in the line of syzygies and the larger in that of quadra-
tures, the ratio of these axes being nearly that of 69 to 70.
Now when the proper eccentricity of the orbit is taken into
account, supposing that eccentricity to be small, Newton
assumes that the form of the orbit in which the moon really
moves will be related to the form of the oval orbit before
mentioned, nearly as an elliptic orbit of small eccentricity with
the earth in its focus is related to a circular orbit about the
earth in the centre. He then attempts to deduce the horary
motion of the moon's apogee for any given position of the
apogee with respect to the sun, and his conclusion is that if C
denote the cosine of double the angle of elongation of the sun
from the moon's apogee, then the mean hourly motion of the
moon's apogee when in that position is to the mean hourly
motion of the moon as
l + Jf<7 : 238^.
The investigation on this point is not entirely satisfactory,
and from the alterations made in the MS. Newton evidently
felt doubts about the correctness of the coefficient ^ which
occurs in this formula.
From this, however, he deduces quite correctly that the
mean annual motion of the apogee resulting would amount
to 38 51' 51", whereas the annual motion given in the Astro-
nomical Tables is 40 41f .
The result stated in the scholium to the 1st Edition appears
to have been found by a more complete and probably a much
more complicated investigation than that contained in the
The papers also contain a long list of propositions in the
Lunar Theory which were evidently intended to be inserted in
a second edition, upon which Newton appears to have been
engaged in 1694. This list, together with the two lemmas on
the motion of the apogee mentioned above, will be found in
Halley inserted in the Philosophical Transactiom of 1721 a
Table of Refractions by Newton, without giving any idea of
the method of its formation.
Kramp, in his Analyse des Refractions, published in 1799,
investigates by a new and powerful analytical method the law
of atmospheric refraction for rays in the neighbourhood of the
On comparing his theoretical results with Newton's Table,
he finds a remarkably close agreement, which is enough to show
that the Table was also the result of theory, and therefore that
Newton must have had some method of his own of solving the
difficult problem of horizontal refraction.
Nothing was known of this method, however, until the pub-
lication of the correspondence between Newton and Flamsteed
by Mr Baily in 1835. In a letter to Flamsteed, dated De-
cember 20th, 1694 1 , Newton tries to explain the foundation of
1 Baily's Flamsteed p. 145.
XIV PEE FACE.
his theory of refraction by giving a theorem from which it is
clear that Newton then understood how to form the differential
equation to the path of a ray of light through our atmosphere.
It is true that, for the sake of greater simplicity in this com-
munication to Flamsteed, Newton restricts the enunciation of
his theorem to the particular case where the density decreases
uniformly as the height increases, but it is obvious from the
form of'the enunciation of Newton's theorem that the method
is general, provided that the differential of the density which is
appropriate to any given law of diminution be employed in
finding the corresponding differential of the refraction. In an
interesting article in the Journal des Savants for 1836, M. Biot
directs particular attention to this subject, and tries to repro-
duce the method which Newton may be supposed to have
employed in order to calculate his table of refractions. M. Biot
closes his article in the following terms :
"II est done prouve, par ce qui precede, que Newton a forme
1'equation differentielle exacte de la refraction pour les atmospheres
de composition uniforme; qu'il Fa appliquee exactement au cas ou
les densites des couches sont proportionelles aux pressions, ce qui
rend leur temperature constante; et qu'enfm, pour ce cas, il a obtenu
les vraies valeurs des refractions a toute distance du zenith, sans
avoir eu besoin d'employer les integrations analytiques qu'il a du
tres-vraisemblablement ignorer. II est done le createur de cette
theorie importante de 1'astronomie physique, qui serait probablement
aujourd'hui plus perfectionee, si Ton avait connu plus tot ses premiers
Judging from Newton's account of the time which he
employed in making these calculations, there must have been a
considerable mass of papers devoted to them which have not
been preserved. Fortunately, however, among the Portsmouth
papers we find a detailed calculation of the refraction corre-
sponding to the altitudes 0, 3, 12 and 30. In order to
make this calculation the path of a ray of light through the
atmosphere is divided into a number of parts subtending given
small angles at the centre of the earth. Hence are found by
the fluxional method quantities which are proportional to the
refractions suffered by the ray in passing over the successive
portions of the path, and from these the actual refractions in
passing over these portions are derived by making the total
horizontal refraction equal to the amount given by observation.
It should be remarked that the above calculation requires an
approximate knowledge of the path of the ray, whereas this
path is at first unknown, and cannot be accurately determined
without a knowledge of the refraction itself. Newton solves
the difficulty by an indirect method, making repeated ap-
proximations to the form of the path, and thus at length
succeeding in satisfying all the required conditions.
The papers show that the well-known approximate formula
for refraction commonly known as Bradley's was really due to
Newton. This formula is only applicable when the object is
not very near to the horizon, but the method of calculation
employed by Newton is equally valid whatever be the apparent
It is well known that in the Principia Newton determines
the form of the solid of least resistance, thus affording the first
example of a class of problems which we now solve by means
of the Calculus of Variations. He there gives what is equivalent
to the differential equation to the curve by the revolution of
which the above-named solid is generated, without explaining
the method by which he has obtained it. Now among the
Newton papers we have found the draft of a letter to a
correspondent at Oxford, no doubt Professor David Gregory,
in which Newton gives a clear explanation of his method, which
is very simple and ingenious. The draft has no date, but from
internal evidence it was probably written about 1694. A
small part of the letter has perished but it is very easy to restore
the missing portion. The letter will be found in the Appendix
at the end of this preface. It may be remarked that a similar
method is immediately applicable to the problem of finding the
line of quickest descent.
A great many of the Newton papers relate to the dis-
pute with Leibnitz about the discovery of Fluxions or the
Differential Calculus. They show that Newton's feelings were
greatly excited on this subject, and that he considered that
Leibnitz had shown towards him in reference to it great
unfairness and want of candour. Newton always maintained
that Leibnitz was the aggressor in this dispute, and that he
had, by his language in the Leipsic Acts, covertly accused him
of plagiarism, whereas he might have known from the corre-
spondence that formerly took place between them, that Newton's
method was in his possession long before he himself became
acquainted with the Differential Calculus.
On the other hand Leibnitz, without avowing himself the
author of the article in the Leipsic Acts, denied that it really
bore the meaning attributed to it by Newton, and maintained
that Newton had either been deceived by a false friend into
imagining that he had been accused of plagiarism, or else that
he was not sorry to find a pretext for attributing to himself the
invention of the new Calculus, contrary to the avowal he had
made in the Scholium in the 1st Edition of the Principia.
From a paper by Leibnitz, which has been published by
Dr Gerhardt, it appears that the article in the Leipsic Acts, of
which Newton complained, was really written by Leibnitz, and it
also seems probable that the ambiguity of its language was not
unintentional. We cannot wonder, then, that Newton, firmly
believing that Leibnitz had charged him with plagiarism,
should have experienced a strong feeling of resentment, and
should have been induced to retort the charge upon his accuser 1 .
It was not unnatural that this embittered feeling should still
survive even after the death of Leibnitz.
, It is clear from these Portsmouth papers that Newton
believed that Leibnitz, during his second visit to England in
October 1676, had obtained access to his MS. entitled De
Analysi per Equationes numero terminorum infinitas, which
was in the hands of Collins, and that he had thus been
materially assisted in discovering the Differential Calculus.
This tract of Newton's is printed in full in the Commercium
Epistolicum, and is there used merely in order to prove
Newton's priority to Leibnitz. It is nowhere asserted or even
implied in the Commercium that this tract of Newton had ever

"Nee lex est justior ilia, etc." (Artis Amatorice, i. 656.)
been seen by Leibnitz. There can now be no doubt, however,
that Newton was right in thinking that Leibnitz had been
shown this MS., since a copy of part of it, in Leibnitz's hand, has
been found among the papers of Leibnitz preserved in the Royal
Library at Hanover 1 . It is, of course, possible that at the time
when this copy was taken Leibnitz was already acquainted in
some degree with the Differential Calculus, but it is difficult to
acquit him of a want of candour in never avowing in the course
of the long controversy respecting the discovery of Fluxions,
that he had not only seen this tract of Newton's, but had
actually taken a copy of part of it. He must have seen, also,
at the same time, that the MS. was an old one, and although
it does not contain the pointed letters which Newton sometimes
but by no means invariably employed to denote Fluxions,
Leibnitz could hardly fail to see, if he was acquainted with the
Differential Calculus, that the principle of Newton's method
was the same as that of his own. It is repeatedly stated by
Newton that what he claims is the first invention of the
method, and that he does not dispute about the particular
signs and symbols in which the method may be expressed.
Again, he often states that although, in the sense which he
employs, the method can have but one inventor, yet the method
may be improved, and the improvements belong to those who
In some of these papers relating to the dispute with Leib-
nitz, Newton gives us some interesting information respecting
the times when several of his discoveries were made. Thus in
a passage, which has been quoted by Brewster 2 , he states that
he wrote the Principia in seventeen or eighteen months, begin-
ning in the end of December 1684, and sending it to the Royal
Society in May 1686, excepting that about ten or twelve of the
propositions were composed before, viz. the 1st and llth in
December 1679, the 6th, 7th, 8th, 9th, 10th, 12th, 13th and 17th,
Lib. i, and the 1st, 2nd, 3rd and 4th, Lib. II, in June and July
1684. The following extract will give an idea of Newton's pro-
digious mental activity at an earlier period of his life.
1 See Gerhardt, Mathem. Schriften Leibnitzens, i. p. 7.
2 Brewster's Life, Vol. i. p. 471.
"In the beginning of the year 1665 I found the method of
approximating Series and the Rule for reducing any dignity of any
Binomial into such a series. The same year in May I found the
method of tangents of Gregory and Slusius, and in November had
the direct method of Fluxions, and the next year in January had
the Theory of Colours, and in May following I had entrance into the
inverse method of Fluxions. And the same year I began to think of
gravity extending to the orb of the Moon, and having found out
how to estimate the force with which [a] globe revolving within a
sphere presses the surface of the sphere, from Kepler's Rule of the
periodical times of the Planets being in a sesquialterate proportion
of their distances from the centers of their orbs I deduced that the
forces which keep the Planets in their Orbs must [be] reciprocally
as the squares of their distances from the centers about which they
revolve : and thereby compared the force requisite to keep the Moon
in her orb with the force of gravity at the surface of the earth, and
found them answer pretty nearly. All this was in the two plague
years of 1665 and 1666 ^ for in those days I was in the prime of my
age for invention, and minded Mathematicks and Philosophy more
than at any time since. What Mr Hugens has published since
about centrifugal forces I suppose he had before me. At length in
the winter between the years 1676 and 1677 2 1 found the Proposition
that by a centrifugal force reciprocally as the square of the distance
a Planet must revolve in an Ellipsis about the center of the force
placed in the lower umbilicus of the Ellipsis and with a radius
drawn to that center describe areas proportional to the times. And
in the winter between the years 1683 and 1684 3 this Proposition
with the Demonstration was entered in the Register book of the R.
Society. And this is the first instance upon record of any Proposi-
tion in the higher Geometry found out by the method in dispute. In
the year 1689 Mr Leibnitz, endeavouring to rival me, published a
Demonstration of the same Proposition upon another supposition,
but his Demonstration proved erroneous for want of skill in the

intrinsic interest, although in writing it so many years after

the events to which it relates, Newton appears to have made
one or two mistakes of date, and probably for this reason has
drawn his pen through the entire passage.
Newton's manuscripts on Alchemy are of very little interest
in themselves. He seems to have made transcripts from a
variety of authors, and, if we may judge by the number of
praxes of their contents which he began and left unfinished, he
seems to have striven in vain to trace a connected system in
the processes described. He has left, however, notes of a
number of his own chemical experiments made at various
dates between 1678 and 1696. Some of these are quantitative.
Those of most interest relate to alloys. He mentions several
easily fusible alloys of bismuth, tin and lead, and gives as the
most fusible that which contains 5 parts of lead + 7 of tin + 12
of bismuth. He says that an alloy consisting of 2 parts of
lead + 3 of tin + 4 of bismuth will melt in the sun in summer.
The alloy which goes by his name is not in the proportions of
either of these two ; but, as he states that tinglas (bismuth) is
more fusible than tin, he could not have used pure metal.
The note-book which contains the longest record of his
chemical experiments contains also the account of a few optical
and other physical experiments and the paper on the decussa-
tion of the optic nerve published by Harris and from him by
Brewster. Harris, according to Brewster, published from a
copy in the Macclesfield Collection; but the copy seems to have
been identical with that in this book, except that a paragraph
at the end is omitted. Brewster overlooked the paper in this
book, though he has quoted from other parts of the book.
The Historical and Theological MSS. cannot be considered
of any great value. A great portion of Newton's later years
must have been spent in writing and rewriting his ideas on
certain points of Theology and Chronology. Much is written
out, as if prepared for the press, much apparently from the mere
love of writing. His power of writing a beautiful hand was
evidently a snare to him. And his fastidiousness as to the
expression of what he wrote comes out very curiously in these
papers; thus there are six drafts of the scheme for founding the
Royal Society, seven drafts of his remarks on the chronology
published under his name at Paris (which made him very angry),
many of the Observations on the Prophecies, several of the
scheme of mathematical learning proposed for Christ's Hospital,
The four elaborately bound volumes, containing ' the Chro-
nology of Ancient Kingdoms Amended/ the Chronicle to the
Conquest of Persia by Alexander, Observations on the Prophe-
cies, and the treatise " De Mundi Systemate," are very remark-
able specimens of their author's care in writing out his works,
and of his beautiful handwriting ( vii. 2). They are all con-
tained in Horsley's collection.
It is believed that in the present catalogue nothing has
been omitted, and that thus a very fair idea may be obtained of
what occupied Newton's time throughout his life. The papers
date from his earliest time, giving his accounts when first he
began college life as a sizar of Trinity College, and his mathe-
matical notes while still an undergraduate: and they continue
till his death. All the papers or books which have been re-
turned to Lord Portsmouth are marked with an asterisk * in
the catalogue. Of the more important letters, which have not
been retained by the University, copies have been taken by
the permission of Lord Portsmouth, and these are retained with
the portion of the MSS. presented by him to the University.
In addition to this a copy of Brewster's Life of Newton has
been placed with the collection, in which the letters there given
have been carefully collated with their originals ; so that prac-
tically the student of Newton's works has all the scientific
correspondence at his command.

Proposition which follows upon it concerning the precession of the
Equinox. The whole is too long to set down. The figure which
feels the least resistance in the Schol. of Prop. xxxv. Lib. n. is
demonstrable by these steps.

2. If the curve line DnNgG be such that the surface of the
solid generated by its revolution feels the least resistance of any
solid with the same top and bottom BG and CD, then the resistance
of the two narrow annular surfaces generated by the revolution of
the [infinitely little lines nN~\ and Gg is less then if the intermediate
solid bgNM be removed [along CB without altering Mb, until
bg comes [to BG], supposing as before that on is equal to Jig,] and by
consequence it is the least that can be, and therefore gG qq is to nN qq
as BG x Bb [is to MN x Mm].
*[Also if] gh be equal to hG so that the angle [gGh is 45 de s r ] then
will Bb qq be [to nN qq as BG x Bb is to] MN x Mm, and by conse-
quence BG qq is to GR qq as BG q is to MN x BR or BG q x BR is to
GR^ [as GR to MN}.
Whence the proposition to be demonstrated easily follows.
But its to be noted that in the booke pag 327 lin. 7 instead of
Quod si figura DNFB it should be written Quod si figura DNFGB,
and that DNFG is an uniform curve meeting with the right line GB
in G in an angle of 135degr.
I have not yet made any experiments about the resistance of the
air and water nor am resolved to see Oxford this year. But perhaps
the next year I may. I had answered your letter sooner but that I
wanted time to examin this Theorem and the Lem. 1 in the 3 d Book.
I do not see how to derive the resistance of the air from the ascent of
water. The reasoning which must be about it seems too complicate
to come under an exact calculus, and what allowance must be made
for the retardation of the water by the contact of the pipe or hole at
its going out of the vessel is hard to know.

* If the altitude of the frustum of the cone spoken of in the preceding para-
graph be infinitely small, the semi-angle of the cone becomes equal to 45.
Hence when the total resistance is a minimum, the curve meets the extreme
ordinate GB at an angle of 45.

are crystallized like salts from juices which turn to stone. At the
end are the gold and silver standards of different countries.

p. 121, note, that on May 10, 1681, and on the 14th and 15th he
comprehended sundry alchemical names. This note has been
scratched out, apparently in consequence of its having nothing to

foregoing experiments have not something to do with it.
p. 122, another note, that on May 18 he completed the solution
of the alchemical symbol of the caduceus, followed by experiments
on June 10 on sublimation of green and blue vitriol with salam-
moniac and the resulting sublimate with lead ore. Perhaps these
experiments on sublimation were designed to test his interpretation
of some alchemical symbols.
