CHAPTER II.

UNDERGRADUATE LIFE AT CAMBRIDGE.

Maxwell did not remain long at Peterhouse; before the end of his

first term he migrated to Trinity, and was entered under Dr. Thompson

December 14th, 1850. He appeared to the tutor a shy and diffident

youth, but presently surprised Dr. Thompson by producing a bundle

of papers--copies, probably, of those he had already published--and

remarking, “Perhaps these may show that I am not unfit to enter at your

College.”

The change was pressed upon him by many friends, the grounds of the

advice being that, from the large number of high wranglers recently

at Peterhouse and the smallness of the foundation, the chances of a

Fellowship there for a mathematical man were less than at Trinity. It

was a step he never regretted; the prospect of a Fellowship had but

little influence on his mind. He found, however, at the larger college

ampler opportunities for self-improvement, and it was possible for him

to select his friends from among men whom he otherwise would never have

known.

The record of his undergraduate life is not very full; his letters to

his father have, unfortunately, been lost, but we have enough in the

recollections of friends still living to picture what it was like. At

first he lodged in King’s Parade with an old Edinburgh schoolfellow,

C. H. Robertson. He attended the College lectures on mathematics,

though they were somewhat elementary, and worked as a private pupil

with Porter, of Peterhouse. His father writes to him, November, 1850:

“Have you called on Professors Sedgwick, at Trin., and Stokes, at

Pembroke? If not, you should do both. Stokes will be most in your line,

if he takes you in hand at all. Sedgwick is also a great Don in his

line, and, if you were entered in geology, would be a most valuable

acquaintance.”

In his second year he became a pupil of Hopkins, the great coach; he

also attended Stokes’ lectures, and the friendship which lasted till

his death was thus begun. In April, 1852, he was elected a scholar,

and obtained rooms in College (G, Old Court). In June, 1852, he came

of age. “I trust you will be as discreet when major as you have been

while minor,” writes his father the day before. The next academic

year, October, 1852, to June, 1853, was a very busy one; hard grind

for the Tripos occupied his time, and he seems to have been thoroughly

overstrained. He was taken ill while staying near Lowestoft with the

Rev. C. B. Tayler, the uncle of a College friend. His own account of

the illness is given in a letter to Professor Campbell[13], dated July

14th, 1853.

“You wrote just in time for your letter to reach me as I

reached Cambridge. After examination, I went to visit the

Rev. C. B. Tayler (uncle to a Tayler whom I think you have

seen under the name of _Freshman_, etc., and author of many

tracts and other didactic works). We had little expedites and

walks, and things parochial and educational, and domesticity.

I intended to return on the 18th June, but on the 17th I felt

unwell, and took measures accordingly to be well again--_i.e._

went to bed, and made up my mind to recover. But it lasted more

than a fortnight, during which time I was taken care of beyond

expectation (not that I did not expect much before). When I

was perfectly useless and could not sit up without fainting,

Mr. Tayler did everything for me in such a way that I had no

fear of giving trouble. So did Mrs. Tayler; and the two nephews

did all they could. So they kept me in great happiness all the

time, and detained me till I was able to walk about and got

back strength. I returned on the 4th July.

“The consequence of all this is that I correspond with Mr.

Tayler, and have entered into bonds with the nephews, of all of

whom more hereafter. Since I came here I have been attending

Hop., but, with his approval, did not begin full swing. I

am getting on, though, and the work is not grinding on the

prepared brain.”

During this period he wrote some papers for the _Cambridge and Dublin

Mathematical Journal_ which will be referred to again later. He was

also a member of a discussion society known as the “Apostles,” and some

of the essays contributed by him are preserved by Professor Campbell.

Mr. Niven, in his preface to the collected edition of Maxwell’s works,

suggests that the composition of these essays laid the foundation of

that literary finish which is one of the characteristics of Maxwell’s

scientific writings.

Among his friends at the time were Tait, Charles Mackenzie of Caius,

the missionary bishop of Central Africa, Henry and Frank Mackenzie of

Trinity, Droop, third Wrangler in 1854; Gedge, Isaac Taylor, Blakiston,

F. W. Farrar,[14] H. M. Butler,[15] Hort, V. Lushington, Cecil Munro,

G. W. H. Tayler, and W. N. Lawson. Some of these who survived him have

given to Professor Campbell their recollections of these undergraduate

days, which are full of interest.

Thus Mr. Lawson writes[16]:--

“There must be many of his quaint verses about, if one could

lay hands on them, for Maxwell was constantly producing

something of the sort and bringing it round to his friends,

with a sly chuckle at the humour, which, though his own, no one

enjoyed more than himself.

“I remember Maxwell coming to me one morning with a copy of

verses beginning, ‘Gin a body meet a body going through the

air,’ in which he had twisted the well-known song into a

description of the laws of impact of solid bodies.

“There was also a description which Maxwell wrote of some

University ceremony--I forget what--in which somebody ‘went

before’ and somebody ‘followed after,’ and ‘in the midst were

the wranglers, playing with the symbols.’

“These last words, however meant, were, in fact, a description

of his own wonderful power. I remember, one day in lecture,

our lecturer had filled the black-board three times with

the investigation of some hard problem in Geometry of Three

Dimensions, and was not at the end of it, when Maxwell came up

with a question whether it would not come out geometrically,

and showed how, with a figure, and in a few lines, there was

the solution at once.

“Maxwell was, I daresay you remember, very fond of a talk upon

almost anything. He and I were pupils (at an enormous distance

apart) of Hopkins, and I well recollect how, when I had been

working the night before and all the morning at Hopkins’s

problems, with little or no result, Maxwell would come in for a

gossip, and talk on while I was wishing him far away, till at

last, about half an hour or so before our meeting at Hopkins’s,

he would say, ‘Well, I must go to old Hop.’s problems’; and, by

the time we met there, they were all done.

“I remember Hopkins telling me, when speaking of Maxwell,

either just before or just after his degree, ‘It is not

possible for that man to think incorrectly on physical

subjects’; and Hopkins, as you know, had had, perhaps, more

experience of mathematical minds than any man of his time.”

The last clause is part of a quotation from a diary kept by Mr. Lawson

at Cambridge, in which, under the date July 15th, 1853, he writes:--

“He (Hopkins) was talking to me this evening about Maxwell.

He says he is unquestionably the most extraordinary man he

has met with in the whole range of his experience; he says

it appears impossible for Maxwell to think incorrectly on

physical subjects; that in his analysis, however, he is far

more deficient. He looks upon him as a great genius with all

its eccentricities, and prophesies that one day he will shine

as a light in physical science--a prophecy in which all his

fellow-students strenuously unite.”

How many who have struggled through the “Electricity and Magnetism”

have realised the truth of the remark about the correctness of his

physical intuitions and the deficiency at times of his analysis!

Dr. Butler, a friend of these early days, preached the University

sermon on November 16th, 1879, ten days after Maxwell’s death, and

spoke thus:--

“It is a solemn thing--even the least thoughtful is touched

by it--when a great intellect passes away into the silence

and we see it no more. Such a loss, such a void, is present,

I feel certain, to many here to-day. It is not often, even

in this great home of thought and knowledge, that so bright

a light is extinguished as that which is now mourned by many

illustrious mourners, here chiefly, but also far beyond this

place. I shall be believed when I say in all simplicity that I

wish it had fallen to some more competent tongue to put into

words those feelings of reverent affection which are, I am

persuaded, uppermost in many hearts on this Sunday. My poor

words shall be few, but believe me they come from the heart.

You know, brethren, with what an eager pride we follow the

fortunes of those whom we have loved and reverenced in our

undergraduate days. We may see them but seldom, few letters may

pass between us, but their names are never common names. They

never become to us only what other men are. When I came up to

Trinity twenty-eight years ago, James Clerk Maxwell was just

beginning his second year. His position among us--I speak in

the presence of many who remember that time--was unique. He was

the one acknowledged man of genius among the undergraduates. We

understood even then that, though barely of age, he was in his

own line of inquiry not a beginner but a master. His name was

already a familiar name to men of science. If he lived, it was

certain that he was one of that small but sacred band to whom

it would be given to enlarge the bounds of human knowledge.

It was a position which might have turned the head of a

smaller man; but the friend of whom we were all so proud, and

who seemed, as it were, to link us thus early with the great

outside world of the pioneers of knowledge, had one of those

rich and lavish natures which no prosperity can impoverish,

and which make faith in goodness easy for others. I have often

thought that those who never knew the grand old Adam Sedgwick

and the then young and ever-youthful Clerk Maxwell had yet to

learn the largeness and fulness of the moulds in which some

choice natures are framed. Of the scientific greatness of our

friend we were most of us unable to judge; but anyone could

see and admire the boy-like glee, the joyous invention, the

wide reading, the eager thirst for truth, the subtle thought,

the perfect temper, the unfailing reverence, the singular

absence of any taint of the breath of worldliness in any of its

thousand forms.

“Brethren, you may know such men now among your college

friends, though there can be but few in any year, or indeed in

any century, that possess the rare genius of the man whom we

deplore. If it be so, then, if you will accept the counsel of

a stranger, thank God for His gift. Believe me when I tell you

that few such blessings will come to you in later life. There

are blessings that come once in a lifetime. One of these is the

reverence with which we look up to greatness and goodness in

a college friend--above us, beyond us, far out of our mental

or moral grasp, but still one of us, near to us, our own. You

know, in part at least, how in this case the promise of youth

was more than fulfilled, and how the man who, but a fortnight

ago, was the ornament of the University, and--shall I be

wrong in saying it?--almost the discoverer of a new world of

knowledge, was even more loved than he was admired, retaining

after twenty years of fame that mirth, that simplicity, that

child-like delight in all that is fresh and wonderful which we

rejoice to think of as some of the surest accompaniment of true

scientific genius.

“You know, also, that he was a devout as well as thoughtful

Christian. I do not note this in the triumphant spirit of a

controversialist. I will not for a moment assume that there is

any natural opposition between scientific genius and simple

Christian faith. I will not compare him with others who have

had the genius without the faith. Christianity, though she

thankfully welcomes and deeply prizes them, does not need

now, any more than when St. Paul first preached the Cross at

Corinth, the speculations of the subtle or the wisdom of the

wise. If I wished to show men, especially young men, the living

force of the Gospel, I would take them not so much to a learned

and devout Christian man to whom all stores of knowledge were

familiar, but to some country village where for fifty years

there had been devout traditions and devout practice. There

they would see the Gospel lived out; truths, which other men

spoke of, seen and known; a spirit not of this world, visibly,

hourly present; citizenship in heaven daily assumed and daily

realised. Such characters I believe to be the most convincing

preachers to those who ask whether Revelation is a fable

and God an unknowable. Yes, in most cases--not, I admit, in

all--simple faith, even peradventure more than devout genius,

is mighty for removing doubts and implanting fresh conviction.

But having said this, we may well give thanks to God that our

friend was what he was, a firm Christian believer, and that his

powerful mind, after ranging at will through the illimitable

spaces of Creation and almost handling what he called ‘the

foundation-stones of the material universe,’ found its true

rest and happiness in the love and the mercy of Him whom the

humblest Christian calls his Father. Of such a man it may be

truly said that he had his citizenship in heaven, and that he

looked for, as a Saviour, the Lord Jesus Christ, through whom

the unnumbered worlds were made, and in the likeness of whose

image our new and spiritual body will be fashioned.”

The Tripos came in January, 1854. “You will need to get muffetees for

the Senate Room. Take your plaid or rug to wrap round your feet and

legs,” was his father’s advice--advice which will appeal to many who

can remember the Senate House as it felt on a cold January morning.

Maxwell had been preparing carefully for this examination. Thus to

his aunt, Miss Cay, in June, 1853, he writes:--“If anyone asks how I

am getting on in mathematics, say that I am busy arranging everything

so as to be able to express all distinctly, so that examiner may be

satisfied now and pupils edified hereafter. It is pleasant work and

very strengthening, but not nearly finished.”

Still, the illness of July, 1853, had left some effect. Professor

Baynes states that he said that on entering the Senate House for the

first paper he felt his mind almost a blank, but by-and-by his mental

vision became preternaturally clear.

The moderators were Mackenzie of Caius, whose advice had been mainly

instrumental in leading him to migrate to Trinity, Wm. Walton of

Trinity, Wolstenholme of Christ’s, and Percival Frost of St. John’s.

When the lists were published, Routh of Peterhouse was senior, Maxwell

second. The examination for the Smith’s Prizes followed in a few days,

and then Routh and Maxwell were declared equal.

In a letter to Miss Cay[17] of January 13th, while waiting for the

three days’ list, he writes:--

“All my correspondents have been writing to me, which is kind,

and have not been writing questions, which is kinder. So I

answer you now, while I am slacking speed to get up steam,

leaving Lewis and Stewart, etc., till next week, when I will

give an account of the _five days_. There are a good many up

here at present, and we get on very jolly on the whole; but

some are not well, and some are going to be plucked or gulphed,

as the case may be, and others are reading so hard that they

are invisible. I go to-morrow to breakfast with shaky men, and

after food I am to go and hear the list read out, and whether

they are through, and bring them word. When the honour list

comes out the poll men act as messengers. Bob Campbell comes

in occasionally of an evening now, to discuss matters and vary

sports. During examination I have had men at night working with

gutta-percha, magnets, etc. It is much better than reading

novels or talking after 5½ hours’ hard writing.”

His father, on hearing the news, wrote from Edinburgh:--

“I heartily congratulate you on your place in the list. I

suppose it is higher than the speculators would have guessed,

and quite as high as Hopkins reckoned on. I wish you success

in the Smith’s Prizes; be sure to write me the result. I will

see Mrs. Morrieson, and I think I will call on Dr. Gloag to

congratulate him. He has at least three pupils gaining honours.”

His friends in Edinburgh were greatly pleased. “I get congratulations

on all hands,” his father writes,[18] “including Professor Kelland

and Sandy Fraser and all others competent.... To-night or on Monday

I shall expect to hear of the Smith’s Prizes.” And again, February

6th, 1854:--“George Wedderburn came into my room at 2 a.m. yesterday

morning, having seen the Saturday _Times_, received by the express

train.... As you are equal to the Senior in the champion trial, you are

very little behind him.”

Or again, March 5th, 1854:--

“Aunt Jane stirred me up to sit for my picture, as she said you

wished for it and were entitled to ask for it _qua_ Wrangler. I

have had four sittings to Sir John Watson Gordon, and it is now

far advanced; I think it is very like. It is kitcat size, to be

a companion to Dyce’s picture of your mother and self, which

Aunt Jane says she is to leave to you.”

And now the long years of preparation were nearly over. The cunning

craftsman was fitted with his tools; he could set to work to unlock the

secrets of Nature; he was free to employ his genius and his knowledge

on those tasks for which he felt most fitted.
