CHAPTER III

JAMES GREGORIE, 1638–1675

‘He learned the art

In Padua far beyond the sea.’

—SCOTT, _Lay_ 1, xi.

James Gregorie, the third son of the minister of Drumoak, was certainly

the cleverest member of that family. He was so clever that no one had

any time to tell anything about him, except his achievements in pure

mathematics and in the science of optics; and indeed from his earliest

days his love for mathematics was such, that his pretty mother unwilling

to wait till her boy was able to go to school taught him herself all she

knew of geometry, sending him away when the time came to the Grammar

School of Aberdeen already far ahead of his class. He studied at

Marischal College, and took his degree (laureated is the pleasant

Scottish word) along with Gilbert Burnet, the readable if imaginative

historian, with whom likely enough he did not find much in common,

representing as they almost did fact and fancy. Now their portraits hang

side by side in the Picture Gallery—Gregorie’s grey and grave and stern,

with an indication of what he was in the mathematical globe by his

side—Burnet’s less severe, satisfied with himself, and a most prosperous

portrait.

After the graduation James Gregorie gave himself up to his studies, and

before he was twenty-four made his great discovery of the Reflecting

Telescope. It was not a chance discovery, for indeed he only described,

and never saw put together, the telescope which bears his name. Anyone

can see them nowadays, for they are still used, and the beautiful one

set up by James Short in Edinburgh, is as clear as the day it was made,

and is not used now, only because a commoner one can do the work which

it did for so many years in the Royal Observatory. To the uninitiated it

has a great merit, for things present themselves through it as they

appear to the naked eye, and not upside down as is the case with most of

the great telescopes.

In 1663, his book entitled _Optica Promota_, which contained a

description of his telescope, was published in London, and thither

Gregorie went, hoping that by the assistance of a practical workman he

might realise his ideal.

His book had been much read by mathematicians, and amongst others by

John Collins, the Secretary to the Royal Society. We can picture then

the mutual pleasure with which these two men met. It was in an alehouse,

where possibly the jolly tavern keeper took the Aberdonian through the

fumes of his stuffy parlour, and presented him to Master Collins as a

likely friend for him; anyway, this was the beginning of a life-long

friendship, and Collins, who had realised at once what a possibility lay

in the proposed reflecting telescope, determined to have a glass made on

the principles which Gregorie had suggested in his book. With this

object in view, he took his new Scottish friend to the most skilled

glass-grinder in London, but, alas! in vain. Mr Reeves could not

overcome the difficulty of obtaining conoidal reflectors, but to the

great mathematicians of that day, and it was a day of giants, the

discovery was magnificent, and from the hands of astronomy’s master

craftsman, the reflecting telescope emerged in 1668 in a more beautiful

form, as Newton’s telescope.

Before Gregorie’s time, the telescopes in England were many of them

immensely long, going up even to three hundred feet, and at this length

they were hardly available for scanning the heavens. The new reflector

brought the size down to six or nine feet, and the idea was so

ingenious, that it made Gregorie famous, and what was more, opened the

door for him to friendship with Newton and Collins, to acknowledgment as

an original worker by Huygens, and awakened in the Father of the

Catholic Church an apprehension that one Gregorie, a Scot and a heretic,

might come to deserve the spiritual blight which he is empowered to give

in placing a book on the Index! It was not so very long before, that

Galileo—an earlier maker of telescopes—had been accused by the learned

scribes and pharisees of his day, of magic. ‘Oh, my dear Kepler,’ says

Galileo to his brother astronomer in one of his most amusing letters,

‘how I wish that we could have one hearty laugh together! Here at Padua

is the principal professor of philosophy, whom I have repeatedly and

earnestly requested to look at the moon and planets through my glass,

which he pertinaciously refuses to do. Why are you not here? What shouts

of laughter we should have at this glorious folly, and to hear the

professor of philosophy in Pisa labouring before the Grand Duke with

logical arguments, as with magical incantations, to charm the new

planets out of the sky!’ It is well that Galileo laughed at this stage

of his life; when he fell into the hands of the Inquisition it became no

laughing matter, and even after he had renounced his views, he was

subjected to many griefs, and to a long incarceration in an Italian

prison.

In the fifty years which intervened between Galileo and James Gregorie,

Louis, the great monarch of France, had taken science under his care, so

the Inquisition was no longer available as a means of preventing the

spread of original thought, and Gregorie, unsuspecting of the pope’s

attitude towards him, went to very Padua itself, and stayed there for

three years.

Padua, with its still colonnades and drowsy population, is visited now,

not in the eager search for learning, but because of the pale frescoes

with which Giotto had gifted it long before Gregorie was there, but in

the seventeenth century, what other attractions drew men thither! Then

such men as Riccioli, Manfredi and De Angelis were drawing the erudite

from far and near to sit at their feet. Such men as Manfredi and De

Angelis, who were they? Alas! they, the great mathematical champions of

their day, have passed into oblivion, and are only remembered now, even

in Padua, by the work of the masons who carved their names on the walls

of the University.

‘In thine halls the lamp of learning

Padua, now no more is burning;

Like a meteor, whose wild way

Is lost over the grave of day,

It gleams betrayed and to betray:

Once remotest nations came

To adore that sacred flame,

When it lit not many a hearth

On this cold and gloomy earth;

Now new fires from Antique light

Spring beneath the wide world’s might:

But their spark lies dead in thee,

Trampled out by tyranny.’

As for Gregorie, he was at variance with Riccioli, De Angelis and

Manfredi, and though we have only negative evidence, we hope that he was

at one with the other great teachers of his time in Italy. _Optica

Promota_ had been much read on the Continent, and there the suggestion

which he made that the solar parallax might be determined by the transit

of Venus and Mercury had been accepted, and till a few years ago it was

the method employed in finding out the distance of the sun. But after

all, the most beautiful piece of Gregorie’s work was his telescope. ‘It

consists of a parabolic concave speculum with a hole in its centre,

having near its focus a small elliptic concave speculum. The image

formed by the large parabolic speculum is received by the small

elliptical one, and reflected through the aperture in the former upon a

lens which magnifies it.’

In Padua his work took a more purely mathematical turn, and resulted in

a book ‘pursuing a hint suggested by his own thoughts,’ of which he had

only a few copies printed. It was entitled _Vera Circuli et Hyperboles

Quadratura_, and Montucla in writing of it says that the title is

misleading, and that the author does not claim, except approximately,

through his infinite converging series to find the square of a circle or

hyperbola. Collins, to whom a copy was sent, read part of it before the

Royal Society. Lord Brouncker and Dr Wallis were enthusiastic in its

praise, and under such encouragement Gregorie published it along with

some fresh matter under the title of _Geometriae Pars Universalis

inservieus Quantitatum Curvarum Transmutationi et Mensurae_. The book

came out in Padua with the permission of the State of Venice, and was a

great success. Before its publication the Royal Society showed their

appreciation of it by making Gregorie a Fellow.

This was in January 1668; in March he was still in Padua, but in all the

confusion of departure, and not long after he returned to Scotland, and

back to his much loved Aberdeenshire, where happiness was awaiting him

on all sides. There was Kinairdy to visit with its many charms, and

there was Aberdeen, and at Elrick there was a cousin who was after all,

it is easy to guess, the end of his journey. This was Mary Burnet, the

widow of John Burnet, who to his great joy consented to become his wife,

and was married to him in 1669.

The astronomer found love-making dreadfully time-consuming, and vaguely

regretted it. You see, it was apt to interrupt his correspondence with

Huygens and Halley, with Newton and Collins, with Dr Wallis and Lord

Brouncker. Here is a pathetic letter from him written in the early part

of the year to one of his mathematical correspondents—‘I have several

things in my head as yet only committed to memory, neither can I dispose

of myself to write them in order and method till I have my mind free

from other cares.’

His wife was only twenty-three, although this was her second marriage,

and even when after Mr Gregorie’s death she married Mr Ædis, she was

still young and very beautiful. A rare piece of her work remains in the

tapestries which adorn the Magistrates’ Gallery in St Nicholas Church in

Aberdeen. Susannah and Jephtha’s daughter were her subjects, and there

they are still, looking out of their panels, from the midst of their

beautiful blue and green landscapes, with the rigid uncertainty of

tapestry portraits. Bailie Burnet would have been proud if he could have

foreseen what a combination of ecclesiastical and civic honour was to

fall to his wife’s needlework.

Mrs Gregorie’s father, George Jameson the artist, drew the pictures for

her. Walpole called him the ‘Van Dyck of Scotland,’ though it is

difficult to know why, as there is really no resemblance in their work,

but at least Jameson and Van Dyck were friends in Rubens’ studio, and

the kindly appreciation of his fellow-citizens has remembered and

repeated the phrase.

In 1670, James Gregorie was appointed to the Chair of Mathematics in St

Andrews, where he had a successful if sometimes vexed life. His duties

were to deliver two lectures a week, and to answer any mathematical

questions that might be set before him. ‘I am now much taken up,’ he

writes in May, 1671, ‘and have been so all this winter by-past, both

with my public lectures, which I have twice a week, and resolving

doubts, which some gentlemen and scholars propose to me. This I must

comply with, nevertheless that I am often troubled with great

impertinences, all persons here being ignorant of these things to

admiration. These things do so hinder me, that I have but little time to

spend on these studies my genius leads me to.’

He lived near the beautiful cathedral and almost under the shadow of St

Regulus, and there his name is still remembered in Gregorie’s Lane and

Gregorie’s Place. He worked in the long, many-windowed library, where

the clock which he used is still at work, and where it has been keeping

time these two hundred years, since Huygens, who invented the use of the

pendulum in clocks, and Gregorie himself were laid at rest.

Huygens and Gregorie had a long feud about his Paduan book. Its faults

as the Dutchman thought were lack of ‘distinguished perspicuity’ and

intricacy in its invention. But Huygens must have lived to regret his

criticisms, however well founded they were, for with a sudden burst of

the M’Gregor spirit, Professor James sent forth a volley of answers, his

official statements through the medium of the Philosophical

Transactions, and his unofficial through his many letters. Neither his

great opponent, nor his great opponent’s allies were spared. ‘I am not

yet so much a Christian as to help those who hurt me. I do not know

(neither do I desire to know) who calleth in that preface, Hugenius his

animadversions of November 12th 1668, judicious, but I would earnestly

desire that he would particularize (if he be not an ignorant) in what my

answer, which is contradictory to Hugenius his animadversions is faulty;

for in geometrical matters, if anything be judicious its contradictory

must be nonsense. I do not know what need there was for an apology for

inserting my answer, but to compliment Hugenius, and violently (if it be

possible) to bear down the truth. I imagined such actions below the

meanest member of the Royal Society, however, I hope I may have

permission to call to an account in print the penners of that Preface.’

The account was never called for, because Newton in the meantime, gave

the simpler solution, which Gregorie had been declaring an

impossibility, but it must be remembered that Gregorie’s method although

almost impossible to any but the most clear mathematical mind, was easy

to him and was correct as far as it went. Can anyone help loving

Huygens, even though they know no more of him than what is seen in his

intercourse with Gregorie? What graciousness and kindness was returned

in exchange for the thunderous treatment he received! Sick, as he

thought he was unto death, he suggested Gregorie as a fit successor to

him in the favour of Louis XIV., and we find his father, who was

secretary to the Prince of Orange and a poet—the poet of the

garden—similarly occupied, trying to influence the great folk with whom

he came in contact to further Gregorie’s interests. But in spite of the

recommendation of the Académie des Sciences, the Royal Society, and such

friends as he had at court, Gregorie never received any Royal patronage;

the want of which he took very calmly and with a great deal of broad

good sense, never having expected any other result. ‘I have had

sufficient experience in the uncertainty of things of that nature before

now, which maketh me since I came to Scotland, how mean and despicable

so ever my condition be, to rest contented and satisfy myself with that,

that I am at home in a settled condition by which I can live. I have

known many learned men far above me upon every account with whom I would

not change my condition.’

In 1669 Gregorie’s books were suppressed in Italy, which came as a shock

to him, and was all the more grievous because it deprived him of many of

his most interested readers—and controversialists! Scotland, however,

supplied the deficiency wonderfully well. There was a professor in

Glasgow called George Sinclair, a mathematician, and a demonologist of

great repute, who wrote a book on Hydrostatics. It was quite clever, and

may have been more interesting to the general reader than books on

Hydrostatics usually are, because of an appendix in which some strange

things were included, amongst others, A Short History of Coal and the

Story of the Devil of Glenluce. The humour of the combination was too

much for Gregorie, and under the name of Patrick Mathers, Arch-Bedal to

the University of St. Andrews, he wrote an answer to the scientific part

of the Hydrostatics, which he called ‘The Great and New Art of Weighing

Vanity.’ Witty, scurrilous, easily written and easily read, the book was

a great source of merriment both to Gregorie and his colleagues at St.

Andrews, and it raised a perfect hurricane in Glasgow. The very name was

an impertinent play on the title of his antagonist’s former book _Ars

nova et Magna_ and the fact that Professor Sinclair was no mean

adversary added zest to the battle, which continued many days. But

Professor Sinclair had prepared an ill reception for his work by the

edict which he had had printed and sent abroad to persuade people to

order copies of it:—

‘Forasmuch as there is a Book of Natural and Experimental Philosophy in

English, to be printed within these four months, or thereabouts; wherein

are contained many excellent and new purposes: As first, Thirty

Theorems, the most part whereof were never so much as heard of before:’

(Alas! poor professor what a beginning! And is the ending any better!)

‘and an excellent way for knowing, by the eye, the Sun or Moon’s motion

in a second of time, which is the 3600 part of an hour, and many others

of different kinds, useful and pleasant. These are therefore to give

notice to all ingenious persons, who are lovers of Learning, that if

they shall be pleased to advance Gedeon Shaw, Stationer at the foot of

the Ladies Steps, three pounds Scots, for defraying the present charges

of the said Book, they shall have from him, betwixt the date hereof and

April next to come, one of the Copies: And for their further security in

the interim the Author’s obligation for performing the same.’

‘Which so exposed to my masters the vanity of that confident man, that

they were forced plainly to let him know their mind,’ wrote the

Arch-Bedal, and some of his own sentiments were expressed in a letter

which he afterwards quoted in the Preface to his book _The Great and New

Art_ ‘Sir,—I admire exceedingly the forwardness of your humor (I will

call it no worse) in your last to ——: he is a person not concerned in

you or in your books, neither will he ignorantly commend anything, as it

seems ye expected he should have done, when ye sent him these papers. Ye

might have known long ago that he had no veneration for what ye had

formerly published, for he made no secret of his mind, when he was put

to it. Ye may mistake him, if ye think that any by-end will cause him

speak what he thinks not: nevertheless he delivered your commission, and

was willing to be unconcerned, expecting their answer. They pressed him

to know his judgment of your last piece: he told ingenuously the truth,

that there was none of them had less esteem for it than himself. He

hopes you are so much a Christian, that ye will not be offended with him

for speaking what he thought when he had a call to it; and yet albeit ye

seem to favour him more than others, he hath ground to look upon himself

as one of the sophistical rabble, for they only are such who condemn

anything ye do, the rest of the University continuing always learned

persons. It is to no purpose to apologize for themselves, ye take all

for granted, which ye have heard: I shall not put you to the pains of

proving it; yet it seems ye would hardly have believed it so easily, had

not your conscience told you, that they had some reason for their

judgement, which really was this following: That they see nothing in

your last piece, new and great (albeit it be _Ars nova et Magna_) save

errors and nonsense; as your demonstrations of the pendulum, your _Nihil

spatiale_, your _Gravitas circularis_, and _horizontalis_, your question

“Whether or no a body may be condensed in a point?” etc., too many to

fill several letters: for ye must not call experiments new inventions,

otherwise ye are making new inventions every day, neither must ye call

different explications new inventions, else the same thing might be

invented by almost every Writer. I admire how ye question the R.

Society; for I desire to know one point of doctrine, which ye or they

either pretend to, concerning the weight of the air, the spring of it,

or anything else in your book, save mistakes, which was not received by

all mathematicians, and the most learned of Philosophers many years

before any of you put pen to paper. Ye have been at much pains to prove

that by experiment, which all the learned already grant, and some have

demonstrat _à priori_ from the principles of Geometry and Staticks, and

many _à posteriori_ from experience if sense may be called a

demonstration: yet ye are the only man who produceth the _Ars Nova et

Magna_ when all others are out of fashion. But more to your

commendation, it seems ye do all these wonders by Magick; for ye have

the ordinair principles of none of these Sciences: Euclid is as much a

stranger as reason in all your Books: and for this _Perque Mathematicos

semper celebrabere fastus_! At last ye come to prove a new doctrine,

which before now was near 2000 years old, with thirty new Theorems which

must not be named because they are of such a tender and delicat

complexion that the very naming of them will make them old. There are

also many other excellent things, which will be all new when they were

but printed yesterday. It is like some of these dayes, we may have an

_Ars Nova et Magna_, to prove that a piece of lead is heavier than so

much cork. I know not wherefore ye undervalue any man, because he hath

not as great esteem for your notions as yourself: Have not we as much

freedom to speak our mind of you, as ye have to write yours of the R.

Society and the University of Glasgow? The greatest hurt ye can do us,

is to make Dromo famulus one of our Principals. I think it not strange

that ye using only demonstrations of sense, should admire the force of

our imagination, in affirming no method of Dyving so good as that of

Melgin. I am sure that the man Dyving for a continual time, if he be not

also of your invention, must breath of the air; and this air must either

be kept close by itself, as in Melgin’s way, or communicat with the air

above. If the latter be your invention, I doubt ye must also have some

Chirurgical invention to apply to your Dyver at his return, if he go to

any great deepness: If the former, it is the same with Melgin’s; and you

cannot neither any man else help it, but in circumstances (which alters

not the method) and perchance to little purpose. As for Archimedes, I am

sure he wanted no necessary requisit to prove the weight of water in its

own Element. I know not what else ye intend to prove: Always I am as

sure that he had two great requisits, which ye want; to wit, Geometry

and a sound head. As to what ye write concerning the imperfection of

Sciences; the scientifical part of Geography is so perfected, that there

is nothing required for the projection, description and situation of a

place, which cannot be done and demonstrat. The scientifical part of

opticks is so perfected, that nothing can be required for the perfection

of sight, which is not demonstrat, albeit men’s hands cannot reach it;

and these being the objects of the fore-said Sciences, your authority

shall not persuade me that it is altogether improper to call them

perfect. In the Hydrostaticks, it were no hard matter to branch out all

the experiments that can be made into several Classes, of which the

event and reason might perfectly be deduced, as consectaries (I speak

not here of long deductions, as ye seem to rant) to something already

published: if it be noticed but rudely (as ye, not understanding what

niceties of proportion means, must do) only considering Motion and Rest:

And I believe there is none ignorant of this who understands what is

written in this Science. Upon this account writing to you, I might call

it perfect, albeit I know there are many things relating to the

proportion and acceleration of the motions of fluids, which are yet

unknown, and may perchance still be. Ye shal not think that I speak of

you without ground; (for in your _Ars Magna et Nova_, ye bring in your

great attempts for a perpetual motion; all which a novice of eight days

standing in Hydrostaticks would laugh at). I do not question that this

age hath many advantages beyond former ages; but I know not any of them,

it is beholden to you for: only I admire your simplicity in this.

Astronomers seek always to have the greatest intervals betwixt

Observations, and ye talk that ye will give an excellent way for

observing the Sun or Moon’s motion for a second of time; that is to say,

as if it were a great matter that there is but a second of time betwixt

your Observations. I wonder ye tell me the eye should be added; for the

invention had been much greater had that been away. I do confess that a

good History of Nature is absolutely the most requisite thing for

learning; but it is not like that you are fit for that purpose, who so

surely believe the miracles of the West, as to put them in print; and

record the simple meridian altitudes of Comets, and that only to halfs

of degrees or little more as worth noticing. However, if ye do this last

part concerning Coal-sinks well, and all the rest be but an _Ars Magna

et Nova_, ye may come to have the repute of being more fit to be a

Collier than a Scholar. Ye might have let alone the precarious

principles and imaginary worldes of Des Cartes, until your new

inventions had made them so: For I must tell you Des Cartes valued the

History of Nature, as much as any experimental Philosopher ever did, and

perfected it more with judicious experiments, than ye will by all

appearance do in ten ages. Ye are exceedingly misinformed, if ye have

heard that any here have prejudice or envy against you; for there is

none here speaks of you but with pity and commiseration: neither heard I

ever of any man who commended you for what he understood. As for your

Latin Sentences, if they be not applied to yourself, I understand them

not; for here we are printing no books, we are not sending tickets

throughout the country to tell the wonders we can do: We are going about

the imployments we are called to, and strive to give a reason for what

we say. Where then are our _Doli et fallaciae, tabulae et testes,

sapientia ad quam putamus nos pervenisse_? etc. In these things ye

publish, ye know there is no Sophistry but clear evidence: If ye had

done such great matters in _Universale et ens rationis_, ye might have

had a shift; but here ye must either particularize your inventions, or

otherwise demonstrat yourself derogatory to the credit of the Nation:

For what else is it to confound R. Societies and Universities with _Ars

Magna et Nova_; and yet when ye were put to it in print, to show your

inventions, all ye could say was, that the publisher should have

reflected upon the wisdom of the Creator, etc., so that the Poet said

well of Democritus, etc., of which I understand not the sense, except ye

make yourself the summus vir, and us all the Verveces. I suppose this

may be the great credit that ye say ye have labored to gain to your

nation; to wit to get us all the honrable title of Wedders. No more at

present, but hoping this free and ingenuous Letter shal have a good

effect upon you (for I am half perswaded, that the flattery of scorners

and ignorants, hath brought you to this height of imaginary learning)

and that when ye come to yourself ye will thank me for my pains.

I rest your humble servant.’

* * * * *

To this letter Professor Sinclair in his turn very pertinently remarked,

that they should not criticise his book till they had seen it, and the

St Andrews’ teachers were convinced. But unfortunately in the address to

the reader with which Professor Sinclair’s _Hydrostaticks_ commences, he

gave expression to his wounded feelings.

‘When this Book was first committed to the press, I sent an intimation

thereof to some of my friends, for their encouragement to it, a practice

now common, and commendable which hath not wanted a considerable

success, as witness the respect of many worthy persons, to whom I am

oblidged. But there is a generation, that rather than they will

encourage any new invention, set themselves by all means to detract from

it and the authors of it; so grieved are they, that ought of this kind

should fall into the hands of any, but their own. And therefore if the

Author shall give but the title of New to his invention, though never so

deservedly, they fly presently in his throat, like so many Wild-Catts,

studying either to ridicule his work altogether—a trade that usually,

the person of weakest abilities, and most empty heads, are better at,

than learned men; like those schollars, who being nimble in putting

tricks, and impostures upon their Condisciples, were dolts, as to their

lesson, or else fall upon it with such snarling and carping as discover

neither ingenuity, nor ingeniousness, but a sore sickness called,

_Envy_.’

* * * * *

Now, indeed, now was the Arch-Bedal justified, and so in hot haste he

wrote that stinging book, which purported to be by Patrick Mathers (the

Arch-Bedal to the University of St Andrews), but was really by Gregorie,

a fact which its erudition must have made clear to Sinclair, even before

that kind person, the mutual friend, had confided the fact to him.

The curious thing was that with all his desire to heap ridicule upon his

adversary, Gregorie only touched upon what would naturally now appear

the most vulnerable point, the passage about the Devil of Glenluce.

In the meantime the clear air of St Andrews was daily suggesting to him

how desirable a place it was in which to teach Astronomy. At night, when

he walked over the links, the stars were so clear above him, and the

hills so inconsiderable on the horizon, that he felt that nowhere in

Scotland was there a site more suitable for an observatory. His idea was

cordially agreed to by the University, and sufficient money had been

collected by 1673 to admit of the authorities commencing their

arrangements. Accordingly Gregorie was commissioned to proceed to the

selection of the instruments needed for the carrying out of his plan.

‘Commission, University of St Andrews, to Mr James Gregorie, Professor

of Mathematics.

‘_10th June 1673._

‘Be it knowen to all men be these presents, Us, Rector, Principals,

Doctors, and Professors of the University of St Andrews, under

subscribing: For as much as we have formerly taken to our serious

consideration the great detriment and losse this ancient seminary hath

been at in times past, and doeth yet sustain by the want of such proper

and necessary instruments and utensils as may serve and conduce for the

better, more solemn and famous profession, teaching and improving of

Naturall Philosophy and the mathematical sciences, and especially for

making such observation on the Heavens and other bodys of this Universe

(as easily may be by such helps, with the great advantage of the pure

air and other accommodation of this place) whereby we may be enabled to

keep correspondence with learned and inquisitive persones in solide

philosophy everywhere, for the forsaid effect: And having purposed (to

be forthcoming to our duty and the encouragement of others) to set as

effectually as may be about this laudable and necessary work, for

providing the forsaids instruments of all kynds, ane observatory, and

all other accoutrements requisite for the improvement of the forsaid

sciences, the benefite, advantage and delight of youth to be trained up

here, the honour of the Kingdom, the reputation of our benefactors, and

the lustre and splendour of the University: Did therefore commissionat

some of our number to make application unto all persons, whom they knew

to be encouragers of learning, and patrons to the professors thereof,

representing unto them that we were instantly upon the effectuating of

the forsaid designe, And to that end to crave their affections and such

other encouragements for the said work as they please to bestow; And to

report to us their diligence therein, with the names of our benefactors,

to the effect this University may record them, and endeavour to make

such respectfull resentments to them and their posterity, as becomes:

giving them power to do every other thing proper and requisit in the

said affair; They being always answerable and accountable to us anent

the premises. And whereas this our laudable designe hath already met

with such considerable encouragement from persons of all ranks, that we

have ordered Mr James Gregorie, professor of the Mathematical Sciences

here to goe to London, and there to provide so far as the money already

received from our Benefactors will reach, such instruments and utensils

as he with advice of other skilful persons shall judge most necessary

and usefull for the above mentioned design: Like as be these presents we

the under subscribers all with one consent constitute the said Mr James

our factor for the effect forsaid, Giving and granting him our full

power and ample commission for transacting and buying the forsaid

instruments in so far as the money forsaid will extend, or as he shall

be further furnished by us upon what is to come upon our letters and

precepts for that effect: Obliging ourselves to ratifye and approve what

the said Mr James should doe in this our commission directed to him by

us during his residence there, and to acquit and relieve him of all

prejudice he may incur and sustain in execution of this our commission,

or any other commission sent by us to him during his residence there:

And to take notice of the fabric and form of the most competent

observatorye that ours here intended may be builded with all its

advantages: And also considering the intended work to be of such moment

and expenss, that we ar not able to accomplish it with the contributions

of these only who have already listed themselves encouragers of it;

Therefore we also by these presents do nominat and constitute the said

Mr James Gregorie our factor and special mandator for making application

unto all whom he knows to be favourers of learning for their concurrence

unto the advancement of the forsd work with full power to do everything

proper and requisit in this affair, as others formerly employed therein

have been impowered by us to do, He being in like manner accountable to

Professor James Gregorie in his search for funds went to Aberdeen, and

there he achieved what was quite the most wonderful success of his

life—he got a church-door collection in all the churches in Aberdeen to

provide for astronomical instruments at St Andrews. Rob Roy need never

have taken to the high hand, if he had a tongue at all as persuasive as

his great cousin!

Here are the Burgh Records for 15th October 1673.[1]

Footnote 1:

Ane collection to be at the Kirk Dores for the Observatorie at Saint

Andrews.

‘_15th Oct. 1673._

‘The said day, Master Alexander Skene, ane of the regents of Saint

Andrewes signifying to the councell that Master James Gregorie,

professor of Mathematics ther, that ther was ane considerable work

intendit in that airt, which before being brought to ane perfectione

woulde stand considerable moneyes and that severall incorporations and

Universities hade contribuit therto, and seeing the said professor was

ane town’s man heir, it was expectit by all concernit, and humblie

desyrit be him, that this burgh wold contribute to the furtherance of

the said work: All which the councell considering, finds it incumbent

upon them not to be wanting for advancement of the said effair in so far

as they are lyable, and therfor appoynts ane collectione to be at the

Kirk dores ... the nixt or subsequent Lord’s day for the forsaid

effect....’

* * * * *

Things were going very smoothly—success was absolutely fawning upon

Gregorie—he was getting money as he wanted it, and the instruments he

had bought were entirely to his mind; but on his return from London,

where he had gone to fulfil his commission, he found everything changed,

and his colleagues, who had once been so kindly to him, had ceased to

regard him as their friend. He was in the curious situation of being

paid by all three colleges, and that in itself would make his position

somewhat difficult, but this difficulty had always existed. The real

cause of dissension was that in his absence the students had been making

popular demonstrations against some of the other teachers, and citing

his lectures as opposed to the theories propounded by them. It was most

uncomfortable for everybody, and everyone in authority determined to

make it most uncomfortable of all for Gregorie. His salary was

suspended, the university servants were told to take no notice of his

orders, and the students were commanded not to attend his lectures, for

certainly the mathematics as taught by him had turned their heads, they

had shown distinct signs of madness. The attitude of the professors was

not unlike that taken up by the country doctor, who when asked to fill

in a form, certifying one of his patients to be insane, put as evidence

observed by himself, ‘he called me a fool!’

In the midst of all the turmoil came a flattering invitation to James

Gregorie to become Professor of Mathematics in Edinburgh University.

After the treatment he had received this was a most blessed chance and

with great joy he left St Andrews, and came to Edinburgh.

The whole story was written to James Fraser, then at Paris:—

* * * * *

‘MUCH HONOURED SIR,—I received some days ago your very obliging letter,

and not long after your arrival at Paris I had another from you, to

which the truth is I was ashamed to answer, the affairs of the St

Andrews Observatory were in such a bad condition, the reason of which

was the prejudice the masters of the University did take at the

mathematics, because some of their scholars finding their courses and

dictates opposed by what they had studied in the mathematics, did mock

at their masters, and deride some of them publicly. After this the

servants of the college got orders not to wait on me or my observations,

my salary was also kept back from me, and scholars of most eminent rank

were violently kept from me, contrary to their own and their parents’

wills, the masters persuading them that their brains were not able to

endure it. These and many other discouragements oblige me to accept of a

call here to the College of Edinburgh, where my salary is here double,

and my encouragements much greater.’

* * * * *

Gregorie left St Andrews somewhat under a cloud, because, as we have

good reason to suppose, he had been teaching Newton’s Philosophy before

the Kingdom of Fife was quite ready for it, and because, too, his

students had more ardour than wisdom in their minds. But in Edinburgh he

had a great reception. The hall where he gave his inaugural address, in

November 1674, was crowded, and he was given perfect freedom in what he

taught. In his observatory he passed many happy hours, and often at

nights he would take his students to look through the telescope at the

stars, to find out belted Saturn and Jupiter with his satellites, which

was not such a nursery affair then as it is now. These phenomena had

only been discovered fifty years before, for let us remember James

Gregorie lived in the days of Charles the Second, and just missed by a

few years being Samuel Rutherfurd’s fellow-citizen in St Andrews.

The last scene in his life comes all too soon, and before he had been a

year in Edinburgh his place was vacant. On an October evening while he

was showing his students the satellites of Jupiter, a sudden blindness

came on, and within a few days everything was over. He probably died of

Bright’s disease.

It seems to us on looking back, as if the active mind had worked too

quickly. Gregorie was only thirty-six, but he had already done a full

life’s work in science. Mengoli, Newton, Huygens, and even Leibnitz (who

for some time claimed Gregorie’s series for his own) have borne witness

to his power. In truth there was something in him that inclined great

men to love him, and his mathematics are so deep that it is only the

master minds who appreciate him. He was a mathematician for

mathematicians.

There are many of Gregorie’s letters still extant, and for the pure

pleasure of reading one just as he wrote it, this letter written to the

Rev. Coline Campbell is inserted.

* * * * *

‘ST ANDREWS, _1. Jan. 1673_.

‘SIR,—I received your of the 23rd of December last, and am glad to have

the occasion to keep a correspondence with such a knowing person as ye

ar. I have not had leasur at this time to satisfie you in your probleme,

being drawn away all this afternoon with necessarie affairs: but with

the nixt I shall doe my endeavour for I expect not to mak the

calculation considerablie short, seing the nature of the question doeth

not suffice it. Our bedal his book against Mr Sinclair is come out

several weeks ago. No more at present, but being in hast and hoping that

ye will be pleased to continue this new correspondence, I rest,

‘Your humble servant,

‘JAMES GREGORIE.

‘for Mr COLINE CAMPBELL.’

His widow and orphans were granted a pension by Charles II. of £40 a

year Scots in recognition of what Gregorie had done in Scotland. No one

could be found suitable to succeed him in the Chair of Mathematics at

Edinburgh. The authorities waited eight years before they made another

appointment; and when the new professor came, he was also a Gregorie, a

nephew of the late professor. His own son, too, held a chair, but that

was in Aberdeen, and he was a professor of medicine.
