THE ROYAL SOCIETY

CELEBRATION OF THE 250iH ANNIVERSARY

Ox the 15th of July 1662 a Charter granted by King Charles II
passed the Great Seal incorporating, under the name of ' The
Royal Society ', a company of eminent and enthusiastic men who
for some years had been prosecuting the study of Natural Science,
or, as it was then termed, Experimental Philosophy. This date
has accordingly been reckoned to be that of the birth of the
Society as an organized association. The approach of the 250th
return of the day suggested that the event was one which might
appropriately be marked by some special form of commemoration.
Hence, early in the year 1911 the President and Council of the
Society determined to make it the occasion of a Celebration
which should be held at a time as near as might be found
convenient to that of the Society's birthday on 15th July
1912.

As an appropriate permanent memorial of the occasion two
volumes were undertaken to be prepared and published (1) a new
edition of the ' Record ' of the Society and (2) a facsimile repro-
duction of the pages of signatures of the Fellows in the Charter-
book, from that of the Royal Founder down to those entered in
the summer of 1912.

The ' Record ', as revised, re-arranged, and enlarged, is intended
to give an account of the foundation and early history of the
Society with the text of all its Charters, its Statutes with their
variations down to the present time, the Society's various Trusts,
lists of its Benefactors, its Presidents and Officers and its Medal-
lists and Lecturers, with an account of its Library, Portraits,
Busts, and Medals, likewise full details regarding the existing
Committees and the various work of the Society. The Chrono-

2 THE ROYAL SOCIETY

logical Register of the Fellows has been thoroughly revised and
for the first time made complete.

The facsimile reproduction of the Signatures has been success-
fully accomplished by the University Press, Oxford, and has been
published in a folio volume with the title, * The Signatures in the
First Journal-book and the Charter-book of the Royal Society.'
This interesting volume contains the autographs of the Fellows
from the first founders down to the present day, and is probably
the most extensive existing collection of the signatures of dis-
tinguished leaders in science during the last two centuries and
a half. Besides the pages of the Charter-book, the volume
also comprises facsimiles of three pages of the first Journal-
book of the Society, on which, under date 5th December 1660,
are inscribed the autograph signatures of the original company
of men of science and their friends and well-wishers who resolved
to form themselves into an organized Society, and who, some
nineteen months later, were incorporated by the King as ' The
Royal Society '. One of the chief difficulties in the preparation of
this facsimile volume arose in the decipherment of many of the
signatures and the compilation of an alphabetical List which
should give accurately the dates of admission into the Society,
with the page of the Charter-book on which each signature would
be found. But in the end every signature was identified, and the
volume together with the ' Record ' were both ready for dis-
tribution by the 13th of July, on which day the President and
Treasurer had the honour of presenting a copy of each volume to
His Majesty King George V, who was graciously pleased to
accept them and to express his interest in the forthcoming
Celebration. Copies of these volumes were subsequently sent to
the Universities, Academies, and other Institutions that were
represented at the Anniversary.

The invitations to be present in London for the purpose of
attending the Society's Celebration began to be issued in January
1912. Each Foreign Member and a number of eminent foreign
men of science who were not Members were specially invited,
and the Universities, Academies, and other learned Institutions in
the United Kingdom, in the British Dominions beyond the Sea,
and in all the civilized countries of the world, were each asked to

send a delegate. The illuminated Invitation was in Latin and in
the accompanying form, with the requisite verbal variations in the
last paragraph when addressed to individual persons.

It was arranged that the various functions should extend from the
evening of Monday, July 15th, to the evening of Thursday, 18th.
The following Diary was printed and placed in the hands of the
Fellows and visitors before the proceedings began :

MONDAY, JULY 15ra.

Evening Reception of the Delegates in the Rooms of the Royal Society,
Burlington House, Piccadilly, 8.30 to 11 p.m. The Enquiry Office will
be open from 9 a.m. to 7 p.m. this day, and on application there,
Delegates and Fellows will obtain all the tickets required for the various
functions of the Celebration.

TUESDAY, JULY 16xH.

Commemorative Service in Westminster Abbey ; 12 noon.

Formal Reception of the Delegates and Presentation of Addresses in the

Great Library of the Royal Society, 2.30 p.m.
Banquet in the Guildhall of the City of London, 6.30 for 7 p.m.

WEDNESDAY, JULY 17TH.

Visits in the morning to Places of Interest in and near London.

Garden Party at Windsor given by Their Majesties the King and Queen.

In the evening Dinner Parties ; particulars of which will await Delegates and

Fellows at Burlington House from the morning of Monday, July 15th,

onward.

The formal Celebration was held in the Rooms of the Royal
Society in Burlington House. For the convenience of those
attending it, an Enquiry Office and Post Office were fitted up
in the adjoining meeting-room of the Geological Society, which
that Society had kindly lent for the occasion, and where all the

B 2

4 THE ROYAL SOCIETY

cards of invitation, tickets, and other documents connected with
the Celebration were obtainable.

A number of the Clubs in the west end of London elected
Foreign and Colonial Delegates Honorary Members during the
time of the commemoration. A Committee of Ladies was formed
for the purpose of providing entertainment for ladies accompanying
delegates, at such times as they would not be present at the
functions of the Society. The meeting-room of the Royal Society
was set apart for the use of these ladies. The Ladies' Committee
took care that some of their number should always be in attend-
ance in that room at specified hours in order to render every
assistance in their power. By wearing different coloured badges
they indicated which of them spoke French, German, or Italian.
They organized visits to the Royal Gardens, Kew, and to places of
interest in London, and some of their number accompanied the
excursionists.

A Register was kept in which every Delegate was requested
to sign his name. This collection of autographs forms an
interesting record which will be preserved among the Society's
archives.

The Royal Society's invitation met with a cordial reception
all over the globe. The great majority of the Universities,
Academies, and other scientific Institutions sent delegates who
presented congratulatory addresses. In cases where delegation
was not attempted the addresses arrived by post together with
many telegrams of felicitation. The following is a brief narrative
of the proceedings throughout the Anniversary :

MONDAY, JULY 15 r rn, 1912.

This being the birthday of the Royal Society the President,
Council, and Fellows assembled in the evening in their Library
for the purpose of informally welcoming such of the Delegates as
had already arrived in London, and settling with them some of
the arrangements for the more formal reception to be held on the
following day. A large proportion of visitors were present, though
some were unable to reach London in time for this meeting.

250TH ANNIVERSARY

TUESDAY JULY 16TH.

By arrangement with the Dean and Chapter, a short com-
memorative service was held at noon in the ancient Abbey of
Westminster. Assembling in the historic Jerusalem Chamber,
the President and Council of the Royal Society, in academic
dress and preceded by the Society's Mace, followed in procession
the Dean and clergy to the places reserved for them. Seats were set
apart for the general body of the Fellows, for the Foreign Members,
and for the Delegates and ladies who had accompanied them.
The music was arranged and conducted by the organist of the
Abbey, Sir Frederick Bridge, C.V.O., Mus.Doc. Towards the
close of the service a short address was given by the Dean, the
Right Reverend Bishop Ryle, C.V.O., D.D., who, at the request
of the Society, has permitted it to be printed here.

ADDRESS BY THE DEAN OF WESTMINSTER.

l Esdras iv. 38, 40, 41. Truth abideth, and is strong for ever ; she liveth
and conquereth for evermore. . . . Blessed be the God of truth. . . . And all
the people then shouted, and said, Great is truth, and strong above all things.

' Magna est veritas, et praevalet. 1

' There have been times even within the memory of some who
are gathered within these walls, when a welcome such as we have
desired to give in this Abbey to the Members of the Royal
Society on the occasion of its 250th Anniversary, would have
received but a faint echo from the religious world of this country.

' The perturbation which took possession of men's minds last
century at the period of the most startling of the discoveries in
Natural Science was wont to betray itself too often in ill-considered
words of fear, impatience, and indignation. Nor need we wonder.
To quote the words of John Fiske : " The men of the present day
who have kept pace with the scientific movement are separated
from the men whose education ended in 1830 by an immeasurably
wider gulf than ever before divided one progressive generation of
men from their predecessors." Misunderstanding, apprehension,
and friction were the result.

6 THE ROYAL SOCIETY

' We look back with regret upon any occasion when the cause
of truth on any of its many sides has been compromised by the
attitude of its defenders ; or when the spirit of charity and
toleration has been forgotten in the wretched atmosphere of
controversy.

' Times are changed. I believe I may claim to speak in the
name of the whole world of contemporary Christian thought,
when in this Abbey I give expression to the gratitude which, as
a rule, we clergy have little opportunity to render, for the amazing
enrichment of human thought which has resulted from the patient
researches of Natural Science during the past two hundred and fifty,
and in particular during the past eighty, years. We thank God for
the great and glorious work that has been done by the men of
science; for the widening of human thought ; for the elevation com-
municated to the methods and ideals of study. " Science," as has
finely been said by an eminent religious teacher in our own day
" science is truly a revelation. . . . Instead of the round world which
cannot be moved, every star that twinkles in the sky becomes
a fiery sun whirling through the deeps of space. Instead of the
six days of creation, we look down vistas of time to which
a thousand years are no more than a watch in the night. Instead
of repeated acts of creation, we see a mighty chain of life
stretching upwards from the sea- weeds and the sponges to where
shall we put a limit to all-enduring patience and all-sovereign
goodness ? "

' With all humility we express our grateful obligation for the
benefits which for a quarter of a millennium have been rendered in
this country by the Royal Society. In no small measure it has
been due to the weight of wise opinion created by its studies and
observations, that the intellectual life of the people has emerged
so far as it has from the influence of the Middle Ages. The work
of the Royal Society has tended to elevate and purify thought.
It is untrammelled by party politics. Its studies overleap the
barriers of race and language. They make for the peace of the
world, as well as for the well-being of every class. They con-
tinually contribute to the promotion of Unity. Truth is one;
and however feebly our words may express it, yet we are convinced

1 Gwatkin, Knowledge of God, ii. 275.

250m ANNIVERSARY 7

that the discoveries of Science discharge a truly prophetic office
in making known to mankind the facts of the Universe, in which
we believe we may read the record of the Will of the Supreme
Mind. And in deepest humility we express our conviction that
the God whose laws are discerned in evolution, gravitation, and
the conservation of energy is He whose laws will be no less
clearly discerned in love, forgiveness, and redemption, in the
spiritual existence and in the gift of immortality.

' We stand, as it were, bareheaded, while you proclaim to
a solemnized and attentive world the wonderful mysteries of the
Universe. You have added sanctity to the knowledge of phe-
nomena ; you have laid deep and lasting the foundations of
accurate research ; you have quickened intellectual life with the
enthusiasm for the investigation of truth. You bid us not stand,
but go forward.

' In conclusion, let me remind you, while I bring to an end this
word of welcome to our Abbey, that we revere in this place the
great names which are famous on your roll of distinction, and
which are no less famous among the memorials committed to our
keeping. Newton and Darwin, Herschel and Adams, Humphry
Davy and Woodward, Buckland, Lyell and Joule, William
Spottiswoode and Stokes and Kelvin, how varied, how illustrious
is this galaxy of men, so simple in their lives, so potent in their
influence ! It is not for me to speak. But I suppose we should
not be wrong to assume that even with the light which the work
of these great men has shed upon the pathway of the progress of
mankind, we have only so far travelled a little way out of darkness.
What may we not in all humility pray for and expect from
the discoveries of Natural Science in the next two hundred and
fifty years ?

' That in the future, as in the past, the work of your Society
may be blessed to the increase of human knowledge, for the good
of our fellow creatures, and in the maintenance of just and
charitable opinion among all classes of the community, is, I am
sure, the earnest prayer of every man who has the fear of God in
his heart.

' " If Reason may not command," said Whichcote, some two
hundred and fifty -years ago, "it will condemn." And it is

8 THE ROYAL SOCIETY

through the pre-eminent influence of the men of the Royal Society
in the field of Natural Science, that we believe that Reason, as
the noblest gift of God to man, will assert its unfailing and bene-
ficent sway, never ceasing to be touched with the passionate search
for the secrets of truth and ever fired with the love of our fellow
creatures, and animated with the generous hope of benefiting them
through the application of scientific discovery. Magna cst veritas,
et praevalet.'

In the afternoon at 2.30 the formal Reception of the Delegates
took place in the Great Library of the Royal Society, which was
completely filled. The Delegates w r ere grouped according to the
countries they represented, these countries being taken in alpha-
betical order. After the visitors had been marshalled to the seats
reserved for each country the proceedings began with an address
from the President, Sir Archibald Geikie, who spoke as follows :

ADDRESS OF THE PRESIDENT.

' On behalf of the Royal Society, I desire to express our warm
appreciation of the sympathetic response which has been made by
so many Universities, Academies, and learned Institutions in all
parts of the world, and by so many distinguished men of science,
to our invitation to celebrate with us on this occasion the 250th
birthday of the Society. No more striking proof than is presented
by this assembly could be given of the reality and cordiality of
that spirit of frank and loyal co-operation which unites into one
great brotherhood the students of science in every land and in
every language. We welcome you, Gentlemen, with our whole
heart. We appreciate most sincerely the honour which has been
conferred on the Royal Society by your presence here to-day. We
greet the Delegates who bring to us the felicitations of some of
the oldest centres of culture in Europe, which had become famous
some centuries before our own Society was born. Not less fully
do we rejoice to meet the Delegates from the younger Institutions
in our own and other lands, who have come from British dominions
beyond the seas, from furthest Asia and Africa, and in such numbers
from the Great Republic across the Atlantic where the lamp of
science now burns with so bright a radiance and in so many

250m ANNIVERSARY 9

centres of growing activity. While it is a proud satisfaction to
receive among our guests to-day leaders in science whose names
have become honoured household words in all parts of the globe,
the gratification is not less to find, among your number, scholars
who represent the older literary learning, who have been deputed
to convey to us the congratulations of the time-honoured Univer-
sities which they adorn. To one and all we return our grateful
thanks for your presence here at our Celebration. We sincerely
desire that the few festal days which you are to spend with us
may be in every way enjoyable to you, so that your impressions
of your visit to London on this occasion may become a pleasant
memory which you will care to cherish in the days to come.

' Two hundred and fifty years seem in some respects no long
span of time in the course of human history, but the two hundred
and fifty years across which we look back to-day have been in the
history of science a period of momentous importance, crowded
with incident, and full of marvellous achievement. When in
the earlier decades of the seventeenth century Francis Bacon was
so cogently insisting on the necessity of studying Nature by the
careful observation of facts and the testing of conclusions by
experiment, he made but slight practical impression in England.
The seed which he sowed did not spring into life until after he
had passed away. About the middle of the century, however, the
spirit of eager curiosity and inquiry with regard to the world
wherein we live, which spread over all civilized countries, reached
England also. Nature was still, as it had been from the earliest
days of mankind, a vast unknown region, full on every hand of
mystery and wonder. Even the most everyday phenomena
presented to thoughtful minds problems for which no satisfactory
solution had been found. The earnest desire to seek an explana-
tion of some of these familiar phenomena at last induced a re-
markable group of men in this country to organize themselves
systematically for the prosecution of that experimental philosophy
which Bacon had so longed to see pursued. The time, however,
was not propitious, for it was one of political turmoil and civil war
in England. The studious men who desired to pursue these
researches sought refuge from the social strife in the quiet
investigation of Nature. They met weekly in London, where they

10 THE ROYAL SOCIETY

discussed many and diverse questions in physical and biological
science, devising and carrying into execution numerous experi-
ments by which they tried to ascertain the nature and connexion
of some of the fundamental processes in the economy of this world.
When the civil commotions drove them from their meeting-place
in London, some of the more active and enthusiastic among their
number sought the shelter of Oxford, where, under the hospitable
roof of Wadham College, they were able to continue their inquiries.
' The restoration of the Monarchy in the early summer of the
year 1660, which led to the re-establishment of settled order in
the country, allowed the resumption of scientific meetings in the
autumn of that year. With the brighter prospects of peace
before them, the philosophers assembled once more in the
picturesque Gresham College in the city of London, and for the
better accomplishment of their aims they determined to form
themselves into a definite Society with a regular organization and
a common fund from which the cost of experiments could be
defrayed. Had they restricted the membership of their proposed
Society to men of science, properly so called, their number would
hardly have exceeded two score. But with commendable fore-
sight they took advantage of the prevalent spirit of curiosity
regarding the secrets of Nature, and gathered round them
a company of three times their own number comprising prominent
representatives of the Church, of Law, of Medicine, of Politics,
and of the Public Services. Their adherents included also men
of letters, and it is specially noteworthy that among these were
the foremost poets in the England of that day John Dryden,
Edmund AValler, John Denham, Abraham Cowley, William
Hammond, and Thomas Stanley. This brilliant assemblage of
the intellect and learning of the time soon attracted the notice and
the active sympathy of King Charles II, who himself had his full
share of the widespread contagion of curiosity and inquiry. He
attended some of the meetings of the infant Society, and on the
15th July 1662 granted to it a Charter of Incorporation with the
name of " The Royal Society " and the definite constitution under
which it is still governed. That date was thus regarded as the
birthday of the Society which, after the lapse of two centuries and
a half, we are met to-day to celebrate.

250TH ANNIVERSARY 11

* The career of the Royal Society is fully recorded in its various
publications. Its "Philosophical Transactions" and "Proceedings",
and likewise the separate works which it has issued, form a chro-
nicle from which the successive stages in the progress of modern
science can be followed. The enumeration of only a few of the
names which appear in these volumes shows that the Society has
counted among its Fellows some of the great leaders in all branches
of Natural Knowledge. Starting its career with a notable group of
physicists and mathematicians, among whom were Robert Boyle and
John Wilkins, it ere long welcomed Isaac Newton into its ranks,
published his immortal " Principia ", and annually elected him as
its President for nearly a quarter of a century. The physical
sciences have all along been strongly represented here. It seems
but yesterday that James Clerk Maxwell's voice was heard in
these rooms and that Stokes and Kelvin sat in the presidential
chair. That the succession of leaders is still well maintained, the
presence here to-day of Lord Rayleigh, Sir William Crookes, Sir
Joseph Thomson, Sir Joseph Larmor, and many others amply
proves. Nor have the biological sciences been less prominent in
the work of the Society. From the early days of John Ray down to
those of Charles Darwin, Hooker, Huxley and Lister, every branch
of biology has been illustrated and advanced by our Fellows.

'As Science knows no restriction of country or language, the
Royal Society has from its earliest beginning cultivated friendly
relations with fellow workers in research all over the world. The
first list of original members includes the honoured name of the
physicist and astronomer Huygens, some of whose gifts to us we
still possess ; and from that time till now the Society has been
proud to inscribe on the roll of its Foreign Members the names of
the most illustrious exponents of science in each generation. It
has been glad also to recognize distinction by the award of its
medals far beyond the bounds of the British Dominions. At the
same time the Academies and Universities of other lands have
ever shown a generous recognition of the labours of the Fellows
of the Royal Society, honouring them by electing them into their
membership or by conferring upon them academic degrees. This
confraternity of the commonwealth of science reaches to-day the
climax of its manifestation in our experience, when we receive

12 THE ROYAL SOCIETY

delegates from so many countries who by their presence here ex-
press the sympathy and goodwill of the various institutions which
they represent. To these institutions, venerable and youthful,
a formal expression of our grateful appreciation will in due course
be transmitted. In the meantime I will conclude these opening
remarks by again thanking you for your presence here to-day and
bidding you a cordial welcome to the halls of the Royal Society.'

The presentation of Addresses from the various Institutions
represented then began. The delegations, as arranged in the
alphabetical order of the countries represented by them, are given
in the following list. As it would have been impossible that the
Addresses should be read at the meeting, one delegate from each
country was selected who should briefly express the friendly
feelings of his compatriots. The Addresses themselves will be
found in extenso from p. 31 to p. 122 of this volume.

On the evening of July 16th the 250th anniversary of the
Royal Society was celebrated by a Dinner held in the ancient
Guildhall of London, which was attended by 490 guests. Besides
the representative Delegates whose names are given in the fore-
going list (p. 13) the company included a large number of the
Fellows of the Society, several members of the Government, the
Ambassadors of France, Italy, and Japan, the Archbishops of
Canterbuiy and York, Cardinal Bourne, the Dean of Westminster,
the Moderator of the Church of Scotland, the Lord Chief Justice
of England, the Master of the Rolls, the Lord Justice Clerk of
Scotland, and representatives of literature, art, and science. After
the usual loyal toasts the toast of ' The Royal Society ' was given
by Mr. Asquith, the Prime Minister, and was responded to by the
President. The * Universities at Home and Abroad ' were pro-
posed by Viscount Morley, Lord President of the Council, and
responses were given by Professor Emile Picard, of the Institute
of France, Professor Waldeyer, of the University of Berlin, and
Professor Winkler, Rector of the University of Amsterdam. The
toast of the * Learned Societies in the Old World and the New '
was proposed by His Grace the Archbishop of Canterbury, and
was replied to by the Marchese E. Paterno di Sessa, of the
Accademia dei Lincei, Rome, Prince Boris Galitzin, of the
Imperial Academy of St. Petersburg, and Dr. R. S. Woodward,
President of the Carnegie Institution, Washington. The last
toast, that of the ' City of London ', was proposed by Dr. Peterson,
Principal of McGill University, Montreal ; and, in the unavoidable
absence of the Lord Mayor of London, a reply was made by the
Right Honourable Sir T. Vezey Strong, the previous Lord Mayor.

22 THE ROYAL SOCIETY

WEDNESDAY, JULY 17TH.

The morning of this day was set apart for visits to places of
interest in London, such as Lambeth Palace, Westminster Abbey,
the British Museum, Bloomsbury, the Natural History Museum,
South Kensington, and the Victoria and Albert Museum.
Arrangements were made by which the several parties of visitors
were conducted over these and other institutions, and the chief
features of each were pointed out by the resident officials.

In the afternoon the Duke and Duchess of Northumberland
gave a Garden Party at Syon House, their residence on the
Thames, to which the Delegates and Fellows of the Royal Society
with their ladies were invited. As the weather was brilliantly
fine, a large company assembled in the picturesque grounds and
enjoyed the summer beauty of an English park.

In the evening a Conversazione was held in the rooms of the
Royal Society at Burlington House, which was numerously
attended. Among the objects of interest presented on the
occasion attention was specially directed to the large collection of
portraits hung on the walls of the tea-room and meeting-room.
In the short handbook which was supplied to the company
a brief account of each picture was given. The portraits are
valuable not only as likenesses of eminent men who have been
connected with the Royal Society, but not a few of them also as
works of art. On the walls of the tea-room hang contemporary
portraits of Francis Bacon, Isaac Newton, Robert Boyle, John
Wallis, John Wilkins, Christopher Wren, John Flamsteed,
Edmund Halley, John Locke, and other early Fellows of the
Society. The meeting-room contains portraits of more recent
Presidents. Among the exhibits shown on this occasion were
the apparatus devised by Mr. C. T. R. Wilson for making visible
the tracks of ionizing particles of vapour condensed upon the ions
set free along the paths ; and also some Cloud-photographs showing
the nature of the ionization produced by different kinds of rays. Sir
William Crookes exhibited his historical collection of Radiometers
and Otheoscopes. Mr. C. V. Boys showed his instrument for
experimenting with rotating soap-films. Some of the historical
relics in the possession of the Society were likewise displayed,
including Robert Boyle's air-pump, Huygens' aerial or tubeless

250TH ANNIVERSARY 23

telescope, Newton's original account of his Reflecting Telescope,
dated January 1672, and some instruments that belonged re-
spectively to Christopher Wren, Joseph Priestley, Captain James
Cook, and Charles Darwin.

THURSDAY, JULY 18TH.

The arrangements for the morning were similar to those of the
morning of the previous day. In the afternoon, the President,
Council, and Delegates went by railway to Windsor, where, by
the King's command, they were first conducted to St. George's
Chapel and thence through the State apartments of the Castle,
where the visitors had an opportunity of seeing the treasures of
art collected by successive sovereigns of England. The whole
company was marshalled on the terrace overlooking the gardens,
the same geographical arrangement of the Delegates being
maintained as at the presentation of addresses in Burlington
House. The King and Queen then came down to the terrace,
and the President, Treasurer, and Secretaries of the Royal Society
were presented to their Majesties by the Lord Chamberlain.
The Delegates were then presented in succession to their Majesties
by the President. After the ceremony of presentation, the
company joined the large Garden Party which their Majesties had
invited to Windsor on the occasion, and the King and Queen,
conversing with their guests on the way, passed to the Royal Tent.

As the whole Celebration was to end on the evening of this
day arrangements were made for a series of farewell dinners,
smaller and less formal than the large banquet in the Guildhall,
when the hospitality could be mingled with more general
friendly intercourse. A number of the Fellows gave parties, at
which Delegates and the ladies accompanying them could see
a little of English homes. The other Delegates were entertained
by the Royal Society Club, a dining club connected with the
Society for some two hundred years. At these various parties much
pleasant conversation took place, the friendships which had been
begun on the previous days were further strengthened, and the
Fellows of the Royal Society bade their guests farewell with the
assurance that the Celebration had passed off as successfully as
could have been desired.

24 THE ROYAL SOCIETY

The various functions arranged by the Royal Society were now
completed, but reference should be made to the sympathetic
action of the Universities of Oxford and Cambridge in organizing
an additional day and inviting a considerable number of Foreign
and Colonial Delegates, together with a few Fellows of the Society,
to partake of the hospitality of these two ancient seats of learning.
On the morning of Friday, the 19th, two parties, about equal in
number, left London for Oxford and Cambridge respectively. At
Oxford the guests took luncheon at All Souls College, with the
Chancellor of the University, Lord Curzon, and the Warden and
Fellows as hosts. A garden-party in the afternoon at Wadham
was full of interest in connexion with the association of this
College with the early history of the Royal Society. The
Warden gave the visitors a brief address in the Lodge wherein
the meetings of the early founders of the Society were held when,
owing to the political troubles of the middle of the seventeenth
century, they could no longer be held in London. At Cambridge
similar hospitality was shown to the guests by the Master and
Fellows of St. John's College.

At both Universities Honorary Degrees were conferred on
a few of the more distinguished men who had attended the
Celebration of the Royal Society. As a permanent and interesting
record of the visits of this day, the Latin eloges pronounced by
the Public Orator of each University are here given. Those at
Oxford (by Mr. A. D. Godley) were as follow :

Hodie eos hospitio excipimus qui Regiam illam Societatem ducentos et
quinquaginta annos peractos celebrantem votis et gratulationibus salutatum
venerunt : quos igitur fautrix et altrix naturalis scientiae Universitas Oxo-
niensis oblata facultate quoad potest titulis exoptat ornare. Ex his primus
ad vos accedit qui antiquissimam omnium scientiam profitetur. Hie origine
Suecanus postea in Russiam invitatus migravit : ibi et aliarum turrium astris
observandis exstructarum et praecipue eius quae est apud Pulkowenses curam
suscepit. Quod si quid de studiis eius loqui audere possum, haec nomine certe
eos referre videntur qui longe aliam illi quidem scientiam e caeli motibus olim
deduxerunt : est enim mathematicus et mathematicas praesertim rationes

250TH ANNIVERSARY 25

astronomiae adhibet. His artibus Enckiani illius cometae cursum et veloci-
tatem est emensus : propter quod insignissimo praemio Astronomica nostra
Societas hominem doctissimum ornavit. Nunc vero habet illud quoque
meritorum testimonium, quod Academiarum illius concilii, quod mox Petro-
poli conventurum esse audimus, Praeses est nuper electus. Praesento ergo
vobis JOHANNEM OSKAR BACKHAND, Turris Speculatoriae Principalis inter
Pulkowenses Curatorem, ut admittatur ad gradum Doctoris in Scientia, honoris
causa.

WALDEMAR C. BHOGGER, University of Christiania.

Eum ad vos duco qui ut geologicae scientiae nullum fere noil genus
tetigit, ita in rupium praecipue et saxorum structura atque elementis
scrutandis mirabilem peritiam atque eruditionem praestitit. Namque patriae
suae litorum et montium formas inspiciendo ea se cognitione imbuit ut
priscarum illarum terrae marisque mutationum velut imaginem exprimere
potuerit : quod qui scripta eius legerit, is glaciei paulatim recedentis tractus
et Oceani modo prolatos modo coartatos fines velut oculis praesens aspicere
videatur. Quid quaeritis ? nihil nisi eruditissime idem et disertissime exposuit :
novas rerum leges tulit et probavit : quamque alii in singulis geologiae parti-
bus diligentiam exercent hie toti illi scientiae adhibuit. Propter illud autem
vix minorem laudem mereri videtur, quod his studiis non otio et securitate
a ceteris curis remotum se dedit, sed curiae suae consiliis et regendae
Universitatis negotiis distractum atque occupatum.

Itaque cum nemo huius temporis in ea quam profitetur scientia cum maiore
laude sit versatus, id quod insigne illud Wollastonianum nuper ei a doctis
viris collatum testatur, praesento vobis WALDEMARUM CHRISTOPHORUM
BROGGER, Mineralogiae et Geologiae Professorem in Universitate Christianiensi,
Rectorem eiusdem Universitatis, ut admittatur ad gradum Doctoris in Scientia,
honoris causa.

WILLIAM B. Scorr, University of Princeton.

Quod in antiquiore orbis terrarum parte a viris magni nominis iam est factum
hie quern videtis in America cuius reipublicae civis est primus effecit. Nam
cum alii geologistae aliis scientiae suae partibus se dederint, hie illuc potissi-
mum incubuit ut quaenam fuerint ea saecla animantum exquireret quae terras
nondum in speciem quam videmus informatas colebant : vestigia eorum
e remotissima antiquitate conservata et inclusas ipsis rupibus reliquias
enucleavit et in lucem produxit : unde nos modo monstrorum magnitudinem
miramur modo notorum hodie animalium fontem atque originem agnoscimus.
Quibus rebus inveniendis multum laboris suscepit: immo in ipsa Patagonia,
qua terrarum regione nihil potest esse ab humanitate seiunctius, tres continues
habitavit annos. Nemo tenebras et crepuscula mundi latiore visu amplexus
est, nemo reperta in rationum formam prudentius composuit. Haec ut

26 THE ROYAL SOCIETY

doctorum virorum consensu ita praecipue Geologicae nostrae Societatis iudicio
comprobantur : namque ea singular! honore et praemio ingeniosissimum
hominem nuper ornavit. Quare praesento vobis WILLELMUM BERRYMAN SCOTT,
Geologiae et Palaeontologiae Professorem Blairianum in Universitate Prince-
tonensi, ut admittatur ad gradum Doctoris in Scientia, honoris causa.

WILHELM WALDEYER, University of Berlin.

Quid est dignius quod ab academicis honoretur quam continuus vitae cursus
uno tenore scientiae finibus proferendis deditus ? Hie enim quern videtis ex
ineunte aevo in anatomiae studio elaboravit, cuius rei est hodie professor :
annum agimus quinquagesimum ex quo primura reperta sua litteris mandare
coeperat : neque postea ullus est secutus quin idem commentariis et libellis
edendis industriam suam atque eruditionem indicaret. In quo temporis spatio
permagnam rerum varietatem scribendo tractavit : modo ovorum partum et
generationem animalium, modo oculos et visus rationem studiis et investiga-
tionibus amplexus est : vix ullam denique quaestionem quae modo ad corporis
humani structuram pertineret intactam reliquit. Neque a doctis hominibus
tantum haec laudantur, sed et omnibus profuerunt : multum enim qui medendi
artem profitentur sunt huius lucubrationibus et consiliis adiuti. Praesento
ergo vobis WILLELMUM WALDEYER, Imperatoris Germanici in Medicina con-
siliarium, Anatomiae Professorem et Anatomici Collegii in Universitate
Berolinensi rectorem, ut admittatur ad gradum Doctoris in Scientia, honoris
causa.

PETER ZEEMAN, University of Amsterdam.

Hominem ingeniosissimum et multum experimentis ausum vobis praesento.
Et quoniam in hoc doctorum virorum consessu loqui posse mihi videor
liberius, quae praecipua fuerit eius famae causa paucis (advertite) docebo.
Nam cum ignis ardentis lumen per vitrum lineis distinctum ita transmitti
sciatis ut non omnes lineae sed secundum eius rei qua utitur naturam aliae
alias immisso lumine fulgeant : hie si vim magnetoelectricam igni adhibueris
commixtos una omnes spectri quod vocant colores in singulis lineis apparere
experiendo demonstravit. Hoc repertum maximi momenti ab iis haberi quibus
cura est primordia rerum quali natura praedita constent investigare, omnes
necesse est agnoscant. Itaque cum hie non modo in lucis ratione elaboraverit
verum etiam ad mundi totius naturae cognitionem multum contulisse videatur,
magnum inter omnes physicistas nomen et laudem consecutus est : neque est
quisquam dignior quern titulo aliquo hoc praesertim die ornemus. Praesento
igitur vobis PETRUM ZEEMAN, Physicae Professorem in Universitate Amstelo-
damensi, ut admittatur ad gradum Doctoris in Scientia, honoris causa. 1

1 Dr. Gabriel Lippmann, For. Memb. R. S. , President of the Academy of Sciences of
Paris, was to have been included among those who received Honorary Degrees, but the
sudden death of Professor Poincare recalled him at once to France.

CAMBRIDGE

The following are the speeches delivered by the Public Orator
(Sir John Sandys) in welcoming the Delegates, on their visit to
Cambridge, and in presenting to the CHANCELLOR (Lord Rayleigh)
the several recipients of honorary Degrees :

In ipso limine laudationum nostrarum, Societatis Regalis tot hospites illustres,
post sacra saecularia feliciter acta, Cantabrigiam hodie invisentes, Academiae
totius nomine iubemus salvere. Unumquemque igitur vestrum salutat et
Baconis et Newtoni et aliorum in scientia natural! aut olim aut nunc insig-
nium virorum Universitas. Dum tot scientiarum inter se diversarum cultores
illustres e tot orbis terrarum partibus ad litora nostra atque adeo Academiae
nostrae ad nemora hodie advectos intuemur, denuo nobis rata esse videntur
vetera ilia prophetae verba: 'plurimi pertransibunt, et multiplex erit scientia.' 1
Tot advenarum illustrium e numero placuit Senatui nostro nonnullos, gentium
inter se diversarum legates, scientiarum inter se diversarum antistites, velut
exempli causa, titulo nostro decorare, qui honos, vestrum omnium praesentia
illustratus, vestrum omnium, ut speramus, benevolentia comprobabitur.

EDWIN B. FROST, University of Chicago.

clari, Societatis Regalis baud ita pridem Praesidis, vestigia secutus, stellas,
quae inerrantes vocantur, diligenter observavit, et spectri (ut dicitur) auxilio,
earum motus aut recedentes aut appropinquantes accurate computavit. Idem,
cum collegis optimis consociatus, stellas duplices atque etiam multiplices pluri-
mas detexit ; siderum denique illorum praesertim, quorum in aere helium inesse
comprobatum est, primus tarditatem quandam motus demonstravit. Astro-
nomo autem nostro, viro impigro, viro acerrimo, tarditatem mentis nemo
exprobrabit. Etenim, talium virorum auxilio, 'caelum ipsum petimus, 1 non

MARQUIS E. PATERNO DI SESSA, University of Rome.

Ex Italia ad nos advectus est regni Italici Britannis amicissimi senator,
coronae Italicae eques clarissimus, qui, Palermi natus, Romae per annos
quadraginta scientiam chemicam experimentis suis luculeuter illustravit.
Peritis notum est hunc virum olim benzenii potissimum progeniem explorasse,
benzenii, quod matris baud pulchrae filiam, filiarum autem suavium et
pulchrarum matrem nominaverim. Notum est eundem postea corpora ex
fluorino, elemento illo impigro, composita, penitus investigasse ; in aliis denique
elementis, bromio praesertim et phosphoro liquido, particularum pondera
accuratius examinasse. Ceterum ha'ec omnia scientiae ad mysteria intima
pertinent, non a nobis vixdum initiatis divulganda. Etenim e scriptoribus
Romanis unus ait, * omnium rerum sunt quaedam in alto secreta ' ; l alter
autem, ' facilius natura intellegitur quam enarratur.' 2 Duco ad vos scientiae
chemicae professorem admodum nobilem, MARCHIONEM EMANUELEM PATERN& DI

IVAN PETROVITCH PAWLOW, Imperial Academy of Sciences of St. Petersburg,
Foreign Member of the Royal Society.

Russorum ex imperio maximo, a nobis remoto sed studiorum communium
in vinculis vicino, ad nos venit physiologiae professor Petroburgensis, qui
ciborum digerendorum rationem universam exploravit, his studiis officinam
quandam dedicavit, physiologiae studiosorum scholam florentissimam fundavit.
Ut alia omittam, quam pulchre ostendit sucos illos, qui cibo concoquendo
inserviunt, non modo mentis motu vario etiam ipsos moveri et mutari, sed
etiam unicuique ciborum generi esse accommodatos, atque omnibus elementis
noxiis adversari et in contrariam partem fortiter contendere. Mentis quidem
certamen Prudentii in carmine quodam heroico narratum vidimus ; corporis
autem certamen, mentisque et corporis societatem intimam ab hoc viro
celebratam audivimus. Talium virorum ex studiis Cornelii Celsi praecepto
illi melius obtemperare possumus : ante omnia corporis sui naturam quisque
norit. 3 Duco ad vos physiologiae professorem egregium, IVAN PETROVITCH
PAWLOW.

CHARLES E. PICARD, of the Institute of France, Foreign Member of the Royal

et generum et operum eius editorem praestantissimum. Reipublicae autem
illi hodie propterea praesertim gratulamur, quod talium virorum consilium,
populi totius cum fructu, totiens expetit. Primum, abhinc annos quattuor et
viginti, praemium ex eadem studiorum provincia reportavit, quam in Scan-
dinavia Abelius primus illustraverat. Idem, scientiarum Academiae Parisiensi
nuper praepositus, quamquam argumentorum in genere quodam abstruso
versatur, stili lucidi lumine libros suos omnes illustravit. Testis est opus
praeclarum de scientiae statu hodierno ad sensum popularem accommodatum ;
testes sunt Analytica ilia, etiam a iuventute Britannica libenter perlecta;
testes etiam illae de methodi analyticae historia Angliae novae in Universitate
quadam nova nuper habitae orationes. Ergo in uno eodemque viro et
mathematici illustris et oratoris optimi habetis exemplar. Duco ad vos
studiorum analyticorum professorem eloquentem, CAROLUM AEMILIUM PICARD.

Germanorum ex imperio maximo, nobis utinam in perpetuum coniunctissimo,
ad nos perlatus est scientiae physicae in Universitate Berolinensi professor, qui,
luce cotidiana non contentus, etiam lucem illam, quae oculorum aciem fugit,
assidue exploravit. Lucem quidem universam ex undis constare electricis,

rem ipsam denuo aggressus, placitis Maxwellianis maxime congruus, lucis

cognitae, sed illis aliquanto breviores quas vis electrica per artem adhibita
generare potuit. Sed, inter has duas undarum varietates penitus exploratas,
iam restat intervallum perbreve, quo sine dubio (fortasse per hospitem nostrum)
propediem expleto, Maxwellii nostri doctrina universa erit patefacta, et, inter
tot rerum naturae miracula, etiam lucis leges melius cognoscentur. Dixit

IMPERIAL ACADEMY OF SCIENCES, VIENNA

HOCHGEEHRTE GESELLSCHAFT ! Gerechter Stolz erfullt unsere Seele, wenn
wir die Errungenschaften auf dem Gebiete der Naturwissenschaften betrachten.
Von den geheimnisvollen Vorgangen in der Natur liegt ein grosser Teil
enthiillt vor unseren Augen. Wir verstehen nicht nur die grossartigen
Vorgange, die der Himmel uns darbietet, wir konnen sogar die Bewegungen
der unsichtbaren Atome beschreiben. Bis zu den Grenzen der Sichtbarkeit
konnen wir noch das organische Leben verfolgen, das so lange ungestort das
Dasein der Menschen gefahrdete. Unzahlige praktische Erfindungen waren
die Folge der wissenschaftlichen Errungenschaften, Erfindungen, welche fur
das Behagen, aber auch fur die Gesundheit der Menschen von hochstem Wer.t
sind, Erfindungen, rait denen wir Raum und Zeit besiegen. Die Erforschung
der Natur war aber auch ein grosser Gewinn fur die moralische Hebung des
Menschengeschlechtes, sie allein war es, die die Menge aus dunklem Aberglauben
befreite, die solchen Verirrungen wie Astrologie, Alchemic usf. ein Ende
setzte. Allergrossten Dank sind wir daher den Mannern schuldig, die durch
ihre Forschungen dieses Emporbluhen der Wissenschaft erzielten. Aber
wenn es auch seit jeher nicht an hervorleuchtenden Geistern fehlte, die
Kometen gleich Licht in die Finsternis strahlten : die neue Richtung brach
sich erst Bahn durch vereintes Streben. Als beim Untergang der Scholastik
in den Menschen allmahlich die Erkenntnis aufdammerte, dass das Studium
der Natur vor Tillem geeignet ist, unseren Geist zu befreien, da zog gerade
in England die neue Richtung zahlreiche Schiller an, die, indem sie in dem
Forschen nach Wahrheit den besten Trost fur die Wirren ihrer Zeit fanden,
sich zu regelmassiger gemeinsamer Arbeit verbanden und alle Teile der
Naturwissenschaft in Angriff nahmen. Das Ansehen und die Zahl dieser
Manner, im Anfange noch die ' Invisibles ', stieg rasch, indem ihre Mitbiirger
den Wert ihrer Studien fur den Fortschritt der Menschheit erkannten.
Konigliche Gnade erhob diese Gesellschaft 1662 zur Royal Society, ein Akt,
welcher der ganzen Welt Vorteil brachte, indem die Royal Society nunmehr

brachte. Ihre Schriften enthalten die Bausteine unseres gesamten heutigen

Eine der jimgsten Akademien, die dem Stern der Royal Society bewundernd
folgt, die kaiserliche Akademie der Wissenschaften in Wien, wiinscht der
Royal Society zu der 250. Wiederkehr ihres Stiftungstages, dass sie in
aller Zukunft ihres Bestandes sich erfreuen und fortfahren moge, eine Letichte

AMPLISSIMAE REGALI SOCIETATI LONDINI. Inter academias liberalium artium,
quae in rerum cognitione et scientiae pervestigatione vigent, Societas Vestra
principatum obtinet secundisque rerum proventibus antiquitus traditis ea
incrementa cepit, in quibus perquam raro alia collegia gloriari possint. Inde
ab ipsis cultus atque humanitatis quasi incunabulis clari et docti viri
Britannorum gentis societatem privatam constituerunt, quae postea tutela regis
Caroli II Regalis nuncupata est, ut non una aliqua in re elaboraret, sed
omnia, praecipue philosophiam, scientiae pervestigatione comprehenderet.
Gravitate et auctoritate sua iam a primordiis domi ad magnum et honoratum
ministerium indicis litterati et consiliarii rerum publicarum curatorum
producta est, foris vero editiones eius ab omnibus hominibus, qui in artibus
versantur, honorem consequuntur. Raro fit ut aliqua litterarum societas
per tarn longum tempus sit industria singulari, sicut Vestra, cui uni omnium
ducentesimum quinquagesimum diem natalem celebrare contigit. Qua ex re
concludi potest Societatem Vestram munere atque officio feliciter functam
esse, nam aliter sentire de societate, cui usus erat cunl luminibus doctrinae,
ut cum clarissimo Newton et cum viris doctis Halley, Simpson, Cavendish,
Wollaston, Priestley, Herschel, Davy et multis aliis, haud licet. Quamobrem
omnes viri docti de his sollemnibus gaudent, imprimis vero Croatarum
Universitas Zagrabiensis ex intimo corde amplissimae Regali Societati gratu-

REGIA SOCIETAS, quae ducentos quinquaginta iam annos stat tanquam
columna ignea omnibus sive apud Britannos praeclaros sive apud reliquas
gentes scientiarum studiosis : quotiescunque difficiliores tractabant quaestiones,
indefesso praelucebat ardore, ut per tenebras et dubia pervenirent ad veritatis
contemplationem. Inter tot nationes, tot doctorum collegia et instituta, quae
gratissimam celeberrimae Societatis memoriam conservant, propter consilia
monitaque in scientiis colendis saepissime ab ea impertita, etiam antiquum
regnum Poloniae cum scholis suis et Academiis locum sibi debitum obtinet.
Itaque decet et convenit ut hoc die glorioso, communi laetitiae destinato,
quando Regia Societas cum superbia bene merita retrorsum per duo saecula cum
dimidio respiciet labores suos ac studia, etiam vox illius regionis audiatur quae
protulit Copernicum, utque iungatur chore mundano gratulatorum. Xeque
mirum videbitur, si muneri gratulandi celeberrimae Societati nomine nationis
Polonae totque generationum studiosorum ac doctorum incumbat detque
operam Academia Scientiarum Cracoviensis, non interruptae traditionis haeres
legitima et vera. Namque ruina libertatis politicae non inhibuit neque inter-
rupit apud Polonos studiorum progressum, erectio vero Imperialis Academiae
Scientiarum Cracoviensis, fundatae a Sua Maiestate, Imperatore Austriae Fran-
cisco losepho I, novarn et firmam addidit disciplinam et temperantiam antiquis
studiis, quae fere numquam cessavere durante regno Poloniae. Iam quadraginta
istis annis, qui praeterierunt ab eius institutione, Academia Cracoviensis,
imprimis vero eius Classis mathematico-physica multis re vera iungebatur vin-
culis Illustrissimae Regiae Societati turn quoad methodum indagationum melius
ediscendam turn ad clarius determinandum inceptorum operum finem ultimum.
Cuius rei testimoniis abundant tantum, quantum sat est, Academiae Cra-
coviensis Annales ; beneficia vero familiaris consuetudinis, concessa nostris
Academicis a nonnullis perquam illustribus membris Regiae Societatis his ultimis
decenniis quantum et quale fuerit, vere non poterit aestimari, nisi mutuum lit-
terarum commercium aliquando in medium proferatur. Itaque gratis animis
multiplices has relationes agnoscentes et revocantes Praeses ac Socii Imperialis
Academiae Scientiarum Cracoviensis, debitam manifestantes venerationem
suam hac occasione laetissima oblata et considerantes magnificam Societatis
Regiae historiam turn praeteritam turn praesentem, ex totis cordibus auguran-
tur ut historia futura non minus sit splendida utque novae scientiae humanae

provinciae inveniantur omnibusque pateant utque Regia Societas per multa
adhuc saecula futura remaneat Britannis gloriosa ac splendens corona, aliis
nationibus auxiliatrix et adiutrix omnis generis studiorum, tandem fraternitatis
mutuae populorum exemplum vivificans, ut omnes se diligant et adiuvent in

quinquagesima natalicia Societatis vestrae quod sollemniter celebratis, gaude-
mus eaque sollemnia votis optimis prosequimur. Simul pia memoria illud
recolimus, quantopere Societas vestra de cultu ac flore scientiarum, ex quo
condita est, meruerit. Nam ilia prima tamquam dux eorum procedebat,
quorum opera studium in omnibus scientiarum naturalium generibus renatum
est, atque ita novas cogitandi vias per omne aevi sui spatium muniebat.
Quando temporum iniquitate bellicisque casibus omnia ferme felicia scientias
colendi initia in Bohemia extincta sunt, agmen virorum in doctrinis elaboran-
tium Societas vestra iam ducebat, effecitque ut aliae similes per Europae terras
conderentur societates. Atque in animum revocandi videntur cum primi illi
viri docti ingeniosi, qui procedente tempore superstitiones e doctrinarum
rationibus propellerent, turn innumerabiles illi rerum investigatores clarissimi,
qui Societati vestrae praepositi exactis quae dicuntur et biologicis disciplinis
velut novas vias docti laboris demonstrabant. Quod tantum ad hanc aetatem
naturales scientiae profecerunt quodque tantum fructum usus earum tulit
hominibus, haec maxima ex parte Societatis vestrae laus est existimanda.
Dum igitur memoria tenemus, quantopere Societas vestra de scientiarum
incremento et flore meruerit generisque humani commoda auxerit provexerit,
verecunde ac pie earn colimus suspicimus, quodque talia tamque utilia et
semper duratura effecit, sincere laetamur totoque animo vobis congratulamur.

ROYAL ACADEMY OF SCIENCES, BRUSSELS

A LA SOCIETE ROYALE DE LONDRES. Monsieur le President, Sir ARCHIBALD
GEIKIE, Associe de 1'Academie royale de Belgique, Vous voulez bien porter
a la connaissance de TAcademie royale de Belgique que la Societe
royale de Londres, fondee, en 1645, par un groupe de savants, en vue du
progres de la science dans le Royaume-Uni, constituee en association des
1660, et investie le 15 juillet 1662, par le Roi Charles II, d'une Charte de
corporation, celebrera le 16 juillet de Tannee actuelle son deux cent cinquan-
tieme anniversaire. Vouz invitez, en meme temps, on ne peut plus confra-
ternellement, 1' Academic royale de Belgique a cette commemoration d'une si
haute importance pour la science, en general, de tous les pays qui s'occupent
de la culture des connaissances humaines en tete desquelles sont TAstronomie
et votre immortel Newton. L' Academic royale de Belgique est on ne peut
plus flatte'e de cette gracieuse invitation de la Societe royale pour laquelle
elle professe la plus grande admiration, non seulement pour ses membres si
illustres, mais aussi pour les travaux dont ils ont enrichi la science europeenne
pendant les deux siecles et demi ecoules de votre celebre Societe. Ce n'est
pas d'hier, illustre Confrere, que nous apprecions la haute valeur scientifique
de la Societe royale et sa valeur morale. Lors de son retablissement par le
Roi Guillaume I er , en 1816, le premier soin de TAcademie royale de Belgique
fut de demander a la Societe royale de Londres 1'echange de ses publica-
tions avec vos celebres Philosophical Transactions. La collection que nous
possedons de ces Transactions remonte a Tannee 1777 ; elle constitue le
plus beau joyau de notre bibliotheque, au meme titre que les publications de
I 1 Academic des sciences de Paris. C'est un tresor inestimable qui fait con-
stamment Tadmiration des savants qui y ont recours pour leurs travaux. Ils
sont legion les membres de la Societe royale que 1'Academie royale de
Belgique a eu Thonneur de compter comme associes depuis 1816. Et leurs
noms sont deja entoures parmi nous, comme en Angleterre, de Taureole de la
gloire : Charles Babbage, Sir John William Herschel, Pierre Barlow, Sir James
South, Sir Edward Sabine, John Barrat, John Taylor, Robert Brown, Sir
David Brewster, Michael Faraday, Sir Richard Owen, Sir Charles Wheatstone,
Sir George Biddell Airy, Sir Roderick Impey Murchison, Sir Charles Lyell,

Thomas Davidson, Charles Robert Darwin, Joseph Dalton Hooker, Andrew
Crombie Ramsay, Thomas Henry Huxley, Lord Kelvin, John Tyndall, James
Prescott Joule, Sir Joseph Prestwich, Arthur Cayley, James Joseph Sylvester,
Sir William Henry Flower. D'autre part, c'est un reel honneur pour nous de
voir encore figurer dans nos rangs Sir George-Howard Darwin, Sir James
Dewar, Sir Edwin Ray Lankester, Sir John Murray et vous meme, Sir
Archibald Geikie, le si distingue president actuel de la Societe royale. II
nous est ^impossible, Sir, dans le cadre de cette Adresse de felicitations, de
citer tous les travaux de votre Societe, meme les plus celebres. Et cependant
1'Academie royale de Belgique aurait ete si heureuse d'en parler, surtout de
ceux qui, depuis le commencement du xvn me siecle, ont fait progresser les
sciences d'une maniere si prodigieuse. D'aussi celebres souvenirs et un aussi
memorable passe, dont la Belgique, comme toute TEurope scientifique, a
profite, sont le plus sur garant d'un avenir qui sera aussi illustre pour la
Societe royale de Londres. L'Academie royale de Belgique souhaite a la
Societe royale d'acquerir encore de nouveaux titres a la reconnaissance de
Thumanite. Puisse-t-elle, a tout jamais, pour le bien de celle-ci, continuer
a tenir avec 1'Academie des sciences de Paris le sceptre de la science qui
constitue le flambeau de la verite. Quant a Lord Lister, 1'Academie, au nom
de toute la Belgique, s'associe au deuil de 1'Angleterre au sujet de la mort de
Tillustre chirurgien. Telle est 1'expression des sentiments de 1'Academie
royale de Belgique, que Tun de ses membres, M. Dollo, s'est engage a vous
apporter de notre part.

Anglorum nationem non victoriis terras expugnando coloniasque late per

illustrem factam esse, quodque nulla cuiquam relinquitur dubitatio quin
accrescens Rerum Naturalium Scientia toti generi humano immane quantum

quam illas communis hominum vitae utilitates magnam partem viris deberi
quos in sociorum numero habuerit. Ingenuo et grato animo eorum beneficio-

TIL ROYAL SOCIETY i LONDON. Grundlseggelsen af Royal Society for
250 Aar siden var en Begivenhed, som ogsaa nu med allerstorste Paaskonnelse
maa mindes af enhver, som glaeder sig over den Hojde, hvortil Nutidens Natur-
videnskab har haevet sig. Ved dets Stiftelse lagdes nemlig Grunden til store
Laere : Bygninger, som siden den Tid ere voksede op, og som ere i Stand til at
baere kommende Tiders rige Arbejder. Uforglemmelige i Videnskabens His-
toric ere de hver paa sit Omraade fremragende Maend, der samledes fbrst i en
mere privat Kreds og dernaest i det af dem grundlagte Selskab for at fore-
tage naturvidenskabelige Forsog i et Omfang og med en Planmaessighed, som
ikke var kendt i tidligere Tider. Om den store Betydning af det Samarbejde
mellem indenlandske og udenlandske Medlemmer, som Royal Society straks
bragte tilveje, vidner den Brevveksling, som med det som Mellemled fortes
mellem Newton og Leibniz, og som indeholder de vigtigste Dokumenter
vedrorende Infinitesimalregningens Tilbliven. Endelig var det under dette
Selskabs Auspicier, at Newton nogle Aar senere, kraftig tilskyndet af dets
ovrige Medlemmer, udgav sine Principia. Disse faa Traek vise den Hoved-
andel, som Royal Society i sine fbrste Decennier havde i Grundlaeggelsen af
den moderne Mathematik, Fysik og Astronomi ; men tidlig udstraktes dets
initiativrige og frugtbringende Virksomhed ligeledes til de andre Omraader
af Naturvidenskaben, og ogsaa efter Udskillelsen af Selskaber med mere
specielle Formaal er Royal Society vedblevet at vaere Centralorganet for den
britiske Nations naturvidenskabelige Arbejde, der har haft og bestandig har
en saa fremragende Andel i de store Fremskridt paa alle Naturvidenskabens

L'UNIVERSITE DE PARIS AU PRESIDENT, AU CoNSEIL ET AUX MEMBRES DE LA

SOCIETE ROYALE DE LoNDRES. LTUniversite de Paris est heureuse de se faire
representer aux fetes donnees par la Societe Royale de Londres a Toccasion
du deux cent cinquantieme anniversaire de sa fondation. Ce fut un jour
memorable que celui ou le roi Charles II transforma en Societe Royale le club
ou se reunissaient chaque semaine quelques curieux de la methode experimen-
tale. Le programme de votre Charte etait de developper la nouvelle philo-
sophie, comme on disait alors, c'est-a-dire la connaissance de la nature au
moven de Inexperience. Votre Societe est toujours restee fidele a son premier
but, et Thistoire de la Science montre avec quel eclat vous avez contribue au
developpement de ce que vous appelez encore aujourd'hui la philosophic
naturelle. On ne peut se reporter aux premiers temps de votre fondation
sans evoquer le souvenir de celui qui fut pendant vingt-quatre ans votre
president, et dont un de vos poetes a dit eloquemment que c'est un honneur
pour le genre humain qu'un tel homme ait existe. Toute louange palit a
cote du nom d'Isaac Newton. II n'est pas une branche des sciences physico-
mathematiques et des sciences naturelles qui n'ait etc enrichie par les travaux
des membres de votre Compagnie. John Dalton et Humphry Davy comptent
parmi les fondateurs de la chimie moderne, et les decouvertes de Faraday et
de Maxwell en electricite ont eu d'immenses consequences. Toute une philo-
sophie se rattache au nom de Charles Darwin, dont les admirables et patientes
observations ont mis en evidence d'importants facteurs de 1'evolution des etres
vivants. Dans le grand labeur jamais termine, par lequel s'edifie peu a peu la
Science, chaque nation apporte sa mentalite particuliere. Vos savants restent
toujours soucieux des details et des applications. Quel bel exemple a donne
un grand physicien, comme Lord Kelvin, dont 1'esprit puissant, capable des
speculations les plus elevees sur la thermodynamique et la theorie des atonies-

Lord Lister qui, en s'inspirant des doctrines pastoriennes, a cree une methode
de pansement bouleversant la chirurgie, et s'est ainsi place parmi les bien-
faiteurs de 1'humanite. La Science est dans une perpetuelle evolution. Les
faits et les principes qui paraissent les mieux etablis restent toujours sujets a
revision. Mais, pour les reviser, il faut parfois une singuliere audace. Elle
ne vous a pas manque. Pres d'ici, des gaz nouveaux, Targon et ses conge-
neres, out ete extraits de 1'air atmospherique tant de fois analyse par les plus
illustres chimistes. (Test dans un laboratoire anglais que fut repris recem-

formation du radium en helium a ete etablie ; ce souvenir, ou sont associees la
science anglaise et la science francaise, est particulierement cher a PUniversite
de Paris. La part aussi est considerable qui revient aux savants de votre
pays dans les vues nouvelles sur les theories electroniques de la matiere.
Depuis deux cent cinquante ans, 1'influence de la Societe Royale n'a cesse de
grandir. Ses Proceedings et ses Transactions comptent parmi les journaux
scientifiques les plus renommes et vont porter au loin le temoignage de votre
activite. Quelle gratitude tous les savants ne doivent-ils pas a la Societe
Royale pour son Catalogue of Scientific Papers pendant le xix e siecle,
entreprise immense, devenue internationale pour le siecle actuel, mais dont
vous avez conserve la haute direction. C'est encore a votre initiative qu'est
due la creation de P Association internationale des Academies ; grace a vous,
le projet, digne du chancelier Bacon, d'une Academic Universelle ouverte a
toutes les nations est devenu une realite. Vous vous etes toujours preoccupes
du role social que doivent jouer les Societes savantes. II n'est pas en Angle-
terre une grande entreprise, ayant un caractere scientifique, sur laquelle vous
n'ayez ete consultes, ou dont vous n'ayez suggere la creation. Qu'il nous
suffise de rappeler, pour des temps recents, le Laboratoire national de Phy-
sique, du a Tinitiative de votre Conseil, et qui reste place sous son controle
direct. Un passe si brillant repond de Tavenir de la Societe Royale. L'Uni-
versite de Paris lui apporte cordialement ses felicitations pour tant d'oeuvres
accomplies. Puissent toujours ses membres, rassembles pour Pavancement de
la connaissance de la nature, suivant les termes de votre Charte deux fois et

de TAngleterre.

42 THE ROYAL SOCIETY

MESSIEURS ET CHERS CONFRERES, Parmi les vceux que vous recevez de tous
cotes, a Toccasion de la celebration de votre deux cent cinquantieme Anniver-
saire, vous distinguerez, nous en sommes assures, ceux que 1' ACADEMIE DBS
SCIENCES DE PARIS nous a charges de vous presenter en son nom. Vous
connaissez de longue date les sentiments qui nous animent, Taffection que
nous vous portons, 1'admiration profonde que nous eprouvons pour vos
travaux. Ces sentiments remontent a nos premieres origines. Notre Aca-
demic et votre illustre Societe ont eu des destinees a peu pres pareilles. L'une
et Tautre ont ete etablies par les amis de la science, longtemps avant d'etre
reconnues par le gouvernement de leur pays. Des le debut du xvn e siecle,
nos savants de Paris avaient pris 1'habitude de se reunir periodiquement, pour
se proposer des problemes de mathematiques, pour faire des experiences, pour
discuter les grandes questions scientifiques que susciterent les decouvertes
de Kepler et de Galilee. Vers la meme epoque, vos philosophes, vos savants,
dont plusieurs vinrent nous rendre visite, se reunissaient a Londres et a Oxford
pour s'occuper, comme les notres, d'experiences et de recherches scientifiques.
Lorsque ces assemblies qui se tenaient dans 1'un et 1'autre pays commencerent
a y etre connues, elles ne tarderent pas a recevoir 1'investiture officielle.
Charles II vous donnait votre premiere Charte en 1662. Quatre ans apres,
en 1666, notre Academie recevait la sienne des mains de Louis XIV et de
Colbert, ' ce ministre porte de lui-meme aux grands desseins ', en meme temps
qu'etait decidee la creation de TObservatoire de Paris. Nos commencements
se ressemblent a plusieurs egards. Par exemple, dans cette premiere partie
de leur carriere, nos Academies ont, Tune et 1'autre, compte parmi leurs
membres d'eminents medecins. II est vrai que les travaux de Newton n'ont
pas tarde a illuminer vos debuts d'un eclat incomparable ; notre Academie
peut revendiquer du moins 1'honneur d'avoir poursuivi et complete Tceuvre
de ce grand horn me. D'Alembert, Clairaut, Laplace, Lagrange figureront
dignement a cote des successeurs que vous avez donnes a Newton dans
Tachevement de la plus glorieuse conquete qu'ait jamais faite Tesprit humain.
Cette union feconde de nos recherches s'est maintenue jusqu'a nos jours.
Lorsque, vers la fin du xvin 6 siecle, Lavoisier a jete les bases de la Chimie
moderne, ses travaux ont ete etroitement meles a ceux de Priestley et de
Cavendish. Au siecle qui vient de finir, et pour ne parler que de ceux qui ne
sont plus, la posterite reunira dans une admiration commune les noms de
quelques-uns de nos confreres, et ceux a jamais illustres d'Herschel, de
Dalton, de Faraday, de Darwin, de Lord Kelvin, de Sylvester, de Cayley,

cTAdams, de Maxwell, d'Huggins, de Lord Lister. Quelque incomplete
qu'elle puisse etre, cette enumeration montre bien que, tout en conservant
Fempreinte de Newton, tout en vous attachant a cultiver cette science
maitresse a laquelle il a donne le beau nom de philosophic naturelle, vous
n'avez neglige aucune branche du savoir humain. La methode qui vous
a guides peut etre aisement definie en quelques mots : Nullius in verba, telle
a ete la devise que la Societe royale a toujours appliquee dans les travaux que,
depuis sa fondation, Elle n'a cesse d'accomplir pour le developpement et
Taccroissement des sciences de la Nature. En repandant ainsi, en faisant
connaitre par vos propres recherches et par les directions que vous donnez,
cette methode scientifique que le Chancelier Bacon avait preconisee avec tant
de force et d'autorite, que Newton avait illustree dans ses Principia et dans
son Optique, vous avez rempli avec eclat la partie essentielle de la tache qui,
de tout temps, a ete devolue aux Societes Savantes ; mais votre action s'est
etendue plus loin encore et vous nous avez donne, sur d'autres points, des
exemples que tous doivent s'efforcer d'imiter. Rattaches a votre gouvernement
par des liens quelque peu laches, qui vous assurent une independance a peu
pres complete, vous avez tenu neanmoins a lui rendre tous les services qu'un
grand pays peut attendre d'une Societe Savante. Vous lui pretez votre
concours pour la distribution des subventions aux recherches scientifiques,
pour la direction de TObservatoire de Greenwich, du Laboratoire national
de physique, pour 1'etude des maladies tropicales qui se rencontrent dans
votre Empire, le plus vaste que le monde ait jamais connu ; vous provoquez,
vous sollicitez sa cooperation pour les expeditions maritimes et scientifiques,
pour les decouvertes geographiques, pour 1'etude des tremblements de terre,
de 1'Ocean dans ses profondeurs, et pour bien d'autres objets que nous
renoncons a enumerer. Tant de travaux, tant de preoccupations sont loin
d'epuiser votre activite; et Ton vous a toujours trouves animes d'un esprit
large et vraiment liberal, prets a susciter et a faire vivre ces associations
internationales qui sont appelees a prendre une place de plus en plus bienfai-
sante dans le developpement et dans la vie de Fhumanite. Naguere, vous
cooperiez avec nous a la creation de TAssociation Internationale des Academies ;
vous avez voulu diriger vous-memes une des entreprises les plus difficiles qui
aient jamais ete tentees : nous voulons parler du Catalogue international de
litterature scientifique^ qui a ete deja, et qui sera plus encore dans Tavenir,
si utile, si necessaire aux chercheurs de tous les pays. Les services que vous
avez ainsi rendus a votre pays, a la science et a Thumanite meritent le respect
et Tadmiration que vous apportent aujourd'hui tant de voix autorisees,
auxquelles nous sommes heureux de joindre les notres. Puissiez-vous prosperer
longtemps encore pour servir d'exemple a nos Societes Savantes, pour offrir
a votre pays et aux savants de toutes les nations une moisson de plus en plus
ample de ces decouvertes qui sont marquees au coin de toutes les qualites,
du genie de votre race ! tel est le voeu bien cordial et bien sincere que vous

sa fondation son salut confraternel et son vceu cordial de prosperite.
Londres et Bordeaux sont unis, depuis pres de deux mille ans, par des liens
qu'ont noues des interets economiques communs, qu'ont resserres des affinites
naturelles et des sympathies inalterables. Des Tepoque romaine Bordeaux
fut le point de depart de la voie qui mene de France en Grande-Bretagne et
dont Londres est le point d'arrivee. Au Moyen Age, pendant trois siecles,
les deux cites eurent des destinees semblables. Le meme roi d'Angleterre, due
d'Aquitaine, qui signa la Grande Charte, donna aux Bordelais ces franchises
communales dont ils gardent pieusement la tradition. La prosperite com-
merciale, nee des echanges entre Londres et Bordeaux, a pour jamais garanti
a notre ville son prestige de metropole du Sud-Ouest de la France. Get

amour des libertes municipales et cette solidarite economique sont les deux
traits caracteristiques de 1'histoire de Bordeaux. Au xviii 6 siecle un nouveau
lien, d'une autre nature, fut noue. Cinquante ans apres Londres, Bordeaux
voulut avoir sa Societe royale, vouee, elle aussi, a Tetude et au progres des
sciences de la nature. Des relations tres nobles, dont nos registres conservent
la trace, s'etablirent entre la jeune Academie bordelaise et son eminente soeur
ainee. L'honneur en revient au membre le plus illustre de notre Compagnie,
a rimmortel penseur qui revela a la France la beaute de la constitution
anglaise, au grand Montesquieu. A la veille de celebrer le deuxieme
centenaire de sa fondation, 1'Academie de Bordeaux est fiere de rappeler
ces souvenirs. Puissent-ils resserrer, d'une faon plus etroite encore, les liens
seculaires de nos deux cites, affermir la cordiale entente de nos deux nations,
gage de la paix du monde !

paroles, qui devaient trouver leur pleine realisation dans 1'ceuvre accomplie
par cette fille posthume de son genie, la Societe Royale de Londres. Depuis
deux siecles et demi, en effet, combien de savants ont passe, qui, apres avoir
explore toutes les parties du vaste monde scientifique, ont rapporte de leurs
voyages, com me un eloquent livre de bord, ces deux cent onze volumes de
vos Philosophical Transactions! Et quelle gloire pour eux d'avoir, sous les
plis du pavilion britannique, combattu le bon combat pour cet imperialisme
de la Science, le plus grand et le plus beau de tous, le seul qui n'enregistre
que des victoires, et dont beneficient tous les peuples ! Au dix-septieme

rompait dans une de ses Fables pour jeter cette reflexion :

welche die Begeisterung fur die Wissenschaft und die Freude an der neuen

Robert Hooke, Robert Boyle und anderen, deren Entdeckungen heute die

Namen wird iiberstrahlt von der leuchtenden Ruhmessonne Isaak Newtons,
des grb'ssten Physikers aller Zeiten und grossten Denkers auf dem Gebiet der

hat dieser gottbegnadete Meister, der wenige Jahre spater der Gesellschaft

Es darf der Jubilarin das hohe Lob gespendet werden, dass sie stets von dem

und zu denen sich im Laufe der Jahrhunderte eine unabsehbare Reihe
hervorragender Forscher auf alien Gebieten der Naturwissenschaften hinzuge-

MONACO

OCEANOGRAPHICAL INSTITUTE

L'INSTITUT OCEANOGRAPHIQTJE fonde par le Prince de Monaco s'associe aux
temoignages de respect que bien des corps scientifiques adressent aujourd'hui
a leur doyenne en songeant avec reconnaissance aux efforts qu'elle fit avant
tout autre pour agrandir le domaine de 1'esprit. Les savants groupes autour
du Prince apportent leurs felicitations pour ce 250 me anniversaire avec un
empressement d'autant plus cordial que les savants anglais sont les premiers
qui aient compris Timportance du role devolu a 1'Oceanographie dans le
progres des connaissances humaines. Cette circonstance est favorable pour
reconnaitre la haute influence que la Societe Royale de Londres a su exercer
sur le developpement scientifique de TAngleterre en faisant naitre parmi les
esprits cultives la puissance de Initiative. (Test ainsi que les grandes
expeditions scientifiques cogues par les savants de TAngleterre ont ete presque
toujours rendues effectives par le concours des particuliers. Souvent TEtat
a joint sa contribution en hommes et en nature aux grandes entreprises telles
que la croisiere du Challenger ; puisse-t-il intervenir plus largement encore
pour la solution des problemes scientifiques dont la recherche etablit mieux
que toute autre manifestation d'energie le prestige moral d'une nation. Un
Etat qui favorise la culture de 1'esprit sans entraver le libre essor des opinions
fait honneur au pays dont il est une emanation. D'ailleurs la Grande
Bretagne qui a montre comment un peuple edifie sa puissance, son prestige et
sa prosperite en respectant ce qu'il y a de noble et d'emouvant dans ses
traditions, la Grande Bretagne possede deja, avec la longue existence de votre
Societe Royale, la tradition scientifique. Aussi une elite intellectuelle vient

54 THE ROYAL SOCIETY

aujourcThui saluer le genie du Peuple Britannique dans une de ses plus belles
fructifications. Les hommes de science ne revendiquent pas un privilege
exclusif dans revolution de la mentalite humaine : de grands cerveaux ont
cultive les elements de celle-ci lorsque la science n'existait pas encore, raais
quand, deja, la recherche de la verite en toute chose lui preparait les voies.
C'est pourquoi nous voulons glorifier la memoire des hommes qui se sont
illustres dans les diverses branches de Tactivite intellectuelle, qui ont repandu
sur la Grande Bretagne les premiers bienfaits de la civilisation moderne,
et dont la renommee se confond avec celle de la Societe Royale.

CELEBRATION ADDRESSES 57

ROYAL ACADEMY OF SCIENCES, AMSTERDAM

THE ROYAL ACADEMY OF SCIENCES OF AMSTERDAM offers its best con-
gratulations to the Royal Society of London on the occasion of the cele-
bration of its two hundred and fiftieth anniversary. In these two hundred
and fifty years Science has reached a high degree of development, to which
the Royal Society, as one of the earliest scientific institutions, has powerfully
contributed. The Royal Academy of Sciences remembers with pleasure the
feelings of friendship which have always existed between the Royal Society
and Dutch scholars throughout the period of its existence. For ever memo-
rable, not only to the Academy, but also to the whole of the Dutch nation,
will be the encouragement which the Royal Society shortly after its founda-
tion gave to Leeuwenhoek by appointing him a Fellow of the Society in 1679,
a distinction highly valued by him, and which has undoubtedly been pro-
motive both to the production and to the spread of his inventions, which he
communicated in a correspondence with the Royal Society extending over
forty-four years. Further the Academy recalls on this occasion with great
acknowledgement, how Christian Huygens, the contemporary and corre-
spondent of Newton, Flamsteed, Boyle, Locke, with which famous men he was
personally acquainted, was one of the first foreign members of the Royal
Society. And how on Boerhaave, also a Fellow of the Royal Society, the
special honour was conferred that Cromwell Mortimer, then Secretary of the
Royal Society, dedicated the thirty-ninth volume of the Philosophical
Transactions to this scholar in 1735. The Royal Academy of Sciences
wishes the Royal Society many years of great prosperity, and expresses the
hope that the mutual feelings of friendship, which have been entertained for
two and a half centuries, may continue to exist in the future.

DUTCH SOCIETY OF SCIENCES, HAARLEM

THE PRESIDENT AND COUNCIL OF THE DUTCH SOCIETY OF SCIENCES offer their
most sincere congratulations to the Royal Society on the occasion of its
250th anniversary. Few Societies can look back on an uninterrupted existence
of two and a half centuries, less on a continuous activity during so long
a time and none on a higher class of scientific work than that published
by the Royal Society. The President and Council of the Dutch Society of
Sciences can therefore frame no better wish, than that the Royal Society may
for many more centuries continue to promote knowledge and consequently
human happiness in the same admirable way as heretofore. For the Presi-
dent and Council of the Dutch Society of Sciences,

tatem vestram fundatam celebratis. Societas nostra, quae isdem studiis
operam dat, vobis successum ex imo pectore gratulatur et ut in posterum
quoque Societati vestrae non modo eadem gloria frui sed etiam magis
magisque crescere detur optat et orat. Quanto studio vobiscum concele-

ROYAL UNIVERSITY OF NORWAY, CHRISTIANIA

THE ROYAL UNIVERSITY OF NORWAY TO THE ROYAL SOCIETY OF LONDON.
Greeting. A quarter of a millennium has elapsed since the foundation of the
Royal Society. Since the days of Boyle and Newton, the Royal Society has
enrolled on its list of members the names of almost all the eminent scientists
of Great Britain, and among these are recorded the illustrious names of
founders of all branches of modern science. Always alive to the vast
importance of science to the various spheres of mental life throughout the
world, the Royal Society has, in all likelihood, contributed more towards
the development and advancement of mankind than any other scientific
association. As a natural consequence of this leading position among

CELEBRATION ADDRESSES 59

scientific institutions, the Royal Society has suggested the foundation of
'the International Association of Academies', and has thus enhanced the
prospect of establishing solidarity within the domains of scientific research
throughout the universe. The innumerable momentous scientific results and
the fundamental ideas this illustrious Society has given to the world merit
the admiration and gratitude of all, especially of the scientific institutions of
all countries. The Royal University of Norway therefore begs to express its
gratitude for the weighty contributions your Society has yielded to the
common work of culture, and tenders heartiest greetings and congratulations
on the occasion of your 250th anniversary, coupled with best wishes for ever
increasing prosperity.

To THE ROYAL SOCIETY. On the occasion of the 250th anniversary of the
Royal Society the SOCIETAS SCIEXTIARUM FENNICA begs to present its sincere
congratulations and to express its admiration and profound esteem. The
Royal Society was already one of the chief centres of science before the time
when the great author of Principia Mathematica became its president. Vast
indeed has been the growth of the knowledge which it has witnessed and,
through its own work, promoted during these two and a half centuries, from
a time when the Mosaic cosmogony held universal sway and the alchemist

64 THE ROYAL SOCIETY

was still striving after the philosopher's stone down to the days of Darwinism,
radioactivity, and the application of science in all departments of human life.
It has seen the birth of many academies, from the antipodes almost to the
polar circle, but ever maintains in their midst its position of leadership. Its
publications, beginning with the Proceedings and Philosophical Transactions,
and ending with the new International Catalogue of Scientific Literature, still
carry out to the full its object: 'to improve Natural Knowledge. 1 To the
many brilliant names which have illuminated its annals, and still do so, new
ones will be added in the future ; and each time a fresh star flashes into being
in this bright constellation one of the greatest in the firmament of science
that admiration will steadily increase which the scientists of the whole world
feel towards your Society. We have the firm conviction that it will, during
a limitless future, continue its truly royal work. On behalf of the Societas
Scientiarum Fennica.

nvoient leurs salutations au President et aux membres de la Royal Society of
London et leur expriment leurs plus vives felicitations a 1'occasion du glorieux
anniversaire celebre les 16, 17 et 18 Juillet. Nombreux sont les rapports qui
se sont etablis depuis 1'epoque de la Reformation entre les hommes de science
de la Grande Bretagne et de la Cite genevoise. Dans une adresse remarquable,
precieuse entre beaucoup, envoyee en 1909 a 1'Universite de Geneve, a 1'occasion
du jubile commemoratif de sa fondation, votre President rappelait les noms
de nos maitres qui ont figure sur la liste d'honneur de la Royal Society. Les
solennites du 250 e anniversaire de la fondation de votre Societe nous rappellent
deux noms de savants anglais qui nous sont chers : celui de Robert Boyle,
dont les grandes decouvertes sont precisement de 1'epoque ou votre illustre
Compagnie s'est constitute, et qui, peu de temps auparavant, passait comme
jeune etudiant deux annees a Geneve ; celui de Sir Humphry Davy qui, apres
avoir sejourne plus d'une fois dans notre ville, y decedait en 1829 et auquel
notre petite Republique, toujours jalouse des prerogatives de la haute culture,
fit des funerailles officielles. Ce souvenir s'est perpetue chez nous sous la
forme d'un prix universitaire qui porte le nom de Davy : recemment encore, la
vie de ce savant illustre etait donnee en exemple a nos etudiants dans une de nos
fetes academiques. II nous a paru utile d'evoquer ainsi le passe pour mieux
exprimer le caractere des liens qui unissent notre Universite a votre savante
Confrerie. Que la Royal Society continue a briller au premier rang des
societes scientifiques ! C'est le voeu tres sincere que forment le Recteur et le
Senat de TUniversite de Geneve.

a vous dire qu'en ces jours de fete nous prenons part a votre joie et que, en
vous presentant nos felicitations pour votre glorieux passe, nous faisons des vreux
pour votre avenir. Creee par le libre effort de quelques hommes avides de
penetrer les secrets de la Science, la Societe Royale a recu, voici deux cent
cinquante ans, sa premiere charte du roi d'Angleterre Charles II. Tot apres,
elle attirait, par ses lettres et ses publications, Tattention de tons les savants et
philosophes du continent. Elle n'a, dans la suite, plus cesse de croitre :
reunissant des materiaux scientifiques, enrichissant sans relache son admirable
bibliotheque, donnant le desir et le pouvoir de vivre a d'autres societes, ses
sreurs cadettes du Royaume Uni, groupant, a chaque generation, des
hommes toujours nouveaux, chercheurs modestes ou initiateurs illustres, qui
prirent part a ses travaux ou, tel le grand Newton, presiderent ses seances.
Aujourd'hui la Societe Royale est plus puissante, plus active que jamais ; elle
rend des services a Phumanite entiere ; il n'est personne, dans le monde de la
culture, qui ne connaisse et respecte son nom. Nous nous joignons a ceux qui
1'admirent et, avec tant d'autres, nous lui exprimons notre reconnaissance.

IMPERIAL UNIVERSITY, TOKYO

ADDRESS OF CONGRATULATION FROM THE IMPERIAL UNIVERSITY OF TOKYO TO
THE ROYAL SOCIETY OF LONDON. (Translation.) The Imperial University of
Tokyo is much honoured in being invited by the Royal Society of London to
participate in the celebration of the two hundred and fiftieth anniversary of
its foundation, and is delighted to join with other Universities and Learned
Societies in tendering most hearty congratulations on this memorable occasion.
So marvellous has been the progress of Science during the last two and a half
centuries, and so illustrious the history of the Royal Society, its foremost
promoter, that we cannot, in this short address, refer in adequate terms to
any of the individual work of its Fellows, however important that work may
be. We can but gratefully recall the fact that the two fundamental laws of
Nature the law of universal attraction and the law of evolution were both
brought to light by the Fellows of the Royal Society, one of whom held the
office of President for the long period of twenty-four years and is, probably,
the greatest man of science the world has ever produced. We would rather
signalize the profound influence which the Royal Society has had upon man's
thought. By steadfastly pursuing the great and noble object with which it
was founded, the Royal Society has not only enlarged the bounds of man's
knowledge and increased his power and happiness to an extent almost beyond
words, but has also, especially during the last half-century, broken down
inherited prejudices and traditional opinions, established freer and more
direct methods of reasoning, and altogether raised the standard and widened
the sphere of man's thought. And, immense as are the material benefits
which Science has conferred upon mankind, this greater intellectual freedom

CELEBRATION ADDRESSES 71

and this wider range of thought, which have chiefly followed from the work
of the Royal Society, are certainly not of less price. Moreover, when we
remember that the bringing in of this liberal mental attitude has been of
immense service in remodelling the civilization of Japan within the last fifty
years, we feel that no words can adequately express our deep sense of
gratitude. If, on this occasion of world-wide significance, we are allowed to
refer to another matter, which still more directly concerns the Imperial
University of Tokyo, we would gratefully record the valuable assistance
rendered to us in past days by several, who have since become Fellows of the
Royal Society, in fostering the spirit of scientific investigation in this country.
We must not omit to express our grateful thanks also for the active part
taken by the Royal Society in initiating and organizing the International
Catalogue of Scientific Literature and the International Association of
Academies. Such international organizations are not only of great impor-
tance for the primary objects with which they have been established, but will
also be a powerful means of promoting the brotherhood of mankind. In
conclusion, the Imperial University of Tokyo tenders its most hearty good
wishes for the prosperity of the Royal Society and hopes that in the future, as
in the past, it may lead the world in ' The Promotion of Natural Knowledge \
On behalf of the Imperial University of Tokyo.

BARON ARATA HAMAO, President.
The fifteenth of June, one thousand nine hundred and twelve.

To THE ROYAL SOCIETY OF LONDON FOR IMPROVING NATURAL KNOWLEDGE,
GREETINGS FROM THE IMPERIAL UNIVERSITY OF KYOTO. The progress of the
world is due to the development of science and art. Especially has the advance-
ment of the physical sciences been a predominant factor in producing the
increased welfare of humanity. The philosophy, the literature, and the Arts
of every age are the flowers of its endeavour ; but it is always the advance-
ment of the physical sciences that increases our knowledge of nature and
points the way to its exploitation, thus substantially promoting the well-
being of mankind. Great Britain has produced many scholars remarkable in
different spheres of human learning ; but those who are distinguished in the
physical sciences are especially numerous. This is due in part to the
innate character of the English people who particularly love positive and
practical knowledge ; yet more especially is it due to those varied means for
promoting and encouraging scientific research in which Great Britain abounds.
The Royal Society of London for Improving Natural Knowledge was estab-
lished with the approval of Charles II, and incorporated in sixteen hundred

and sixty-two. It is the oldest scientific association in Great Britain, and
one of the oldest in the world. Among its fellows are included those of the
greatest scientific eminence in Great Britain; and by their indefatigable
activity in the realm of natural science and by their keen counsel, the Society
has wonderfully fulfilled its purpose. The institution, by the Society, of the
annual grants for the promotion of scientific research, and of awards of
various medals to those making important discoveries, has been of great
service to the progress of knowledge in physical sciences. The publications of
the Society are among the most useful agencies for encouraging and dis-
seminating scientific information throughout the world ; and by them Japan
has been greatly benefited. The Imperial University of Kyoto appreciates
highly the Society's cordial invitation to participate in the celebration of its
two hundred and fiftieth anniversary, and herewith commissions her repre-
sentative to attend the ceremony, paying honour to the Society's glorious past
and praying for its still more glorious future.

Neque enim fieri poterat quin series ilia mirabilis rerum inventarum per
quas toti generi humane non solum via et ratio naturam complectendi sed
etiam vitae condicio cotidianae tantum in melius mutata esset, nos quoque
penitus commoveret. Nam si primam memoriam ordinis vestri repetere libet
et recordari quam longe aliter de specie et ratione naturae illo atque hoc
tempore vulgo senserint, difficile est eis satis digne gratias agere qui ingeniis
studiisque effecerunt ut hodie et qualia sint foedera naturae tanto subtilius
intellegamus et qualis necessitudo inter hominem ipsum et universam naturam
intercedat tanto liberius iudicemus. Longum est nee vero hoc loco necesse
eminent enim omnibusque qui sapiunt in ore sunt eos recensere paene innu-
merabiles qui vestrae Societatis sodales se in caecas veri latebras insinuave-
runt atque inde victores quid fieri posset, quid nequiret rettulerunt. Duo
autem, Carolus Lyell et Carolus Darwin, summo ingenio praestantes, nullius,
ut vobis moris est, addicti iurare in verba magistri, rerum cognoscere causas
tarn feliciter potuerunt ut si quis reperta eorum praetermittere velit, nullo iam
modo neque de hoc orbe terrae neque de vi et natura animantium neque de
ipsa omnium hominum consortione quicquam recte cogitare queat. Hi et tot
alii ex ordine vestro illustrissimo vitam humanam per inventas artes excolue-
runt omnesque sui memores iure fecerunt merendo. Namque eos, ut ait
Lucretius divinus ille poeta,

paulatim docuit pedetemptim progredientis :
sic unum quicquid paulatim protrahit aetas

UNIVERSITY OF WISCONSIN

To THE ROYAL SOCIETY OF LONDON. THE UNIVERSITY OF WISCONSIN sends
to the Royal Society of London its congratulations on the two hundred and
fiftieth Anniversary of its foundation, a memorable event in the history of the
oldest and most noted scientific society of the English-speaking people. Its
long roll of members contains the names of many men who have initiated
great movements in science, and includes others less distinguished by whose
wisdom and labour science has become enriched. By the lives and work of
these men the Royal Society has contributed in large measure to the great
intellectual heritage of England, and through that nation to the enlightenment
and freedom of the human race. The University of Wisconsin, while gratefully
recognizing with all the world of learning this unique service, has the con-
fident belief that the Royal Society during the centuries to come will continue
its illustrious history.

ROYAL SOCIETY OF TASMANIA, HOBART

THE PRESIDENT, ROYAL SOCIETY OF LONDON. Sir, The President, Council,
and Members of the ROYAL SOCIETY OF TASMANIA desire, most cordially and
sincerely, to offer to the Royal Society of London their heartiest congratu-
lations on the two hundred and fiftieth Anniversary of its foundation.
Honoured by the name of the parent Society, and working to promote its
objects in Tasmania, we join with other kindred bodies in gratefully recalling
the past of the Royal Society of London, rich in names of men who have
profoundly influenced the progress of Science, and who for such service have
gained world-wide renown. On this Anniversary not the least cause of pride
in the great work of the Society must be the thought that its methods and
ideals are animating the lives of men in parts of the world entirely unknown
to its distinguished founders. We, at this time, also recall the fact that

82 THE ROYAL SOCIETY

it was at the instance of the Royal Society of London that Captain James
Cook was sent out by the English Admiralty on that voyage which led
to such remarkable results in the history of these Southern Lands, results
none the less famous in Science from the labours of Sir Joseph Banks,
afterwards your President for over forty years. The Royal Society of
London has ever been pre-eminent in promoting the highest ideals of
knowledge and truth. It has helped in a unique degree to mould the
intellectual life not only of Britain but also of Europe and the whole civilized
world. While it is impossible to estimate the enormous influence that has
radiated from it during the two and a half centuries of its existence, yet this
aspect may be specially noted : there can be no national bond stronger than
that of common scientific interest, and in carrying out its more definite
objects the Royal Society of London has also been eminently assisting to
draw closer the political and social bonds of the Empire. The Royal Society
of Tasmania names as its delegate and representative to convey this greeting,
GREGORY SPROTT, M.D., Member of the Council. Signed on behalf of the
Council and Members of the Royal Society of Tasmania.

ROYAL SOCIETY OF VICTORIA, MELBOURNE

THE PRESIDENT, COUNCIL, AND MEMBERS OF THE ROYAL SOCIETY OF VICTORIA,
a humble but aspiring unit of the body of seekers after knowledge, send hearty
greetings to the Royal Society of London, its great mother and prototype, on the
completion of the 250th year of its valuable life. The faithful work of many
devoted students of nature in the London Society has brought fresh light into
countless dark places, and the stimulus given by them, rolling like a wave to the
remotest corners of the British Empire, inspires distant workers in the fields
of science with energy and hope to new endeavours. The Royal Society of
Victoria gratefully acknowledges its debt to these noble men, and ventures to
trust that the efforts of its own members to emulate the work of the parent
Society may have added some vigour to the growth of the Tree of Knowledge,
that by continuing so to do it may be for ever weaving fibres of kinship that
shall assimilate its results ever more closely to those of its illustrious progenitor.
By order of the Council :

J. R. HOGG, Fellow of the Royal Society of Victoria, Delegate
to the Meetings celebrating the 250th anniversary of the
foundation of the Royal Society of London.

UNIVERSITY OF BOMBAY

To THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY or
LONDON, on the occasion of the 250th Anniversary of the Constitution
of the Society by Royal Warrant. THE UNIVERSITY OF BOMBAY, in accepting
the invitation of the President, Council, and Fellows of the Royal Society
of London to send a delegate to the celebration of the two hundred and
fiftieth Anniversary of its constitution by King Charles II, desires to convey
through its representative, DR. F. G. SELBY, M.A. (Oxon.), LL.D. (Bom.),
its cordial felicitation, and to express its sympathetic interest in the historical
commemoration of one of the most important events in the history of
scientific inquiry in any part of the world. In the University of Bombay,
as in every other seat of learning and research, the influence of the Royal
Society has been a stimulus to investigation and interpretation in many
different fields, and it is with gratitude that the University desires to share
in the celebration. The University of Bombay is specially anxious to be
identified with the celebration because the Royal Society has during its
history taken such a very large interest in the development of inquiry in the

CELEBRATION ADDRESSES 85

tropics and specially in India. Several of its leaders, and notably Sir Joseph
Banks, President of the Royal Society in the latter part of the eighteenth
century, and Sir Joseph Dalton Hooker, one of its most eminent members
in the nineteenth century, spent much of their life and strength in investigation
into tropical conditions, and were almost the first to draw attention to the
important light which such inquiry would shed on general scientific questions.
The interest in tropical and Indian questions has not flagged since that time,
and the Society has again and again placed its experience at the disposal
of the Government of India and private bodies in this country. At the
present time it acts as the adviser of the Indian Government on matters
connected with scientific inquiry in India, and also as an advisory body
on the management of the Observatories in India. It has Committees which
are studying tropical diseases which are among our worst scourges. And the
Royal Society has always shown itself willing to assist with advice and counsel,
any public body which appealed to it. The University of Bombay, therefore,
joins in congratulating the Royal Society of London on the present occasion,
on the noble part it has played in the advancement of knowledge in the past,
and wishes for it a future even more glorious, in which it will appear that the
present commemoration represents but the beginning of a new era of advance-
ment and usefulness.

Bombay, June 20th, 1912.

UNIVERSITY OF CALCUTTA

A CONGRATULATORY ADDRESS TO THE ROYAL SOCIETY

1. Those who daily improve the modern world by new discoveries, who
spend their lives in search after truths about the material world, who plunging
deep into the ocean of science collect gems, may those sober-minded scientists
live for ever for the benefit of this world.

2. Many learned men were born, will be born, and are being born on this
earth which was created long ago ; but indeed there are few who are really
successful and who by diving into the ocean of science have found out hidden
gems.

3. The Creator, hoary with age, created the universe with the earth and
other elements ; but surely he concealed the forces of material objects.
A new creator, more powerful than the first, being born discovered the long-
hidden forces of material objects.

4. In the store-house of the universe created by the aged sage Brahma
many precious things were kept hidden ; but Newton breaking open the doors
of superstition revealed a new method of discovery.

5. May the bright glory of the Royal Society, founded by him, continue to
shine through Royal patronage as long as the Sun and the Moon endure. It

86 THE ROYAL SOCIETY

is time for us to celebrate the jubilee, now that it has completed its two
hundred and fiftieth year of existence.

6. Electricity, fire, water, and other elements that were ever known as
inanimate things caught in the machines (of the Society) toil like ghosts
discharging vapour (tears), and constantly propel steam-ships, etc. during the
day and night : seeing this wonderful mechanical skill the Creator himself is
now surprised.

7. Within London lies the famous tank, called the Royal Society, in whose
waters of science on white lotuses plays the Goddess of Learning in her
splendour and where the Sun of knowledge never sets but always shines out of
joy. To add to the beauty of that tank we send this fresh blooming lotus
(Praphullachandra) of our own country.

8. May the garland of this poem composed by Asutosh and presented by
him with deep regard be accepted. If the savants living in the garden of
science wear it as an ornament, then his labour will be requited.

rejoice at the sight of this union of ours, so beneficial to the world. Vibhvana,
Vaja and Rbhu, celebrated in the Rig Veda, these three together rejuvenated
their old father and attained to heaven. Still higher and all unrivalled is the
region that you have reached by rejuvenating the old world through Science
and Art.

Vayu, Varuna, Agni, the Asvins, Rudras and Vasus, worshipped by the
Aryans of old, have been praised in beautiful hymns in the Vedas ; through
thy constantly employing all of them in devoted service for the good of
humanity, thy glory, moving among the regions of the air and the waters,
extends over the earth. Having come to congratulate thee, O [Society] of
glorious fame and unequalled majesty, I am satisfied with thy various virtues.
Mayest thou live long, patronize the learned, and be highly honoured for the
good of the world.

UNIVERSITY OF LEEDS

To THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY. THE
UNIVERSITY OF LEEDS begs respectfully to congratulate you on the Anniversary
which you are about to celebrate. For two hundred and fifty years your
Society has filled a unique place in our national life. No institution has
ever been animated by a greater love of truth or by a deeper reverence for
unfettered freedom of thought. The experimental methods followed by the
Royal Society have proved themselves to be true methods of advance ; and
to-day mankind is its debtor for the enlightenment and the welfare which
attend vast additions to natural knowledge. The scientific achievements of
your Society are universally acknowledged both at home and abroad. A point
less generally observed is its indirect influence in all parts of the British
realms. Happily inclusion in the Royal Society does not withdraw and
isolate men who have found a career among the growing populations of our
time. No thoughtful dweller in our own city can help feeling that Leeds
would have lost greatly had Joseph Priestley never lived and worked here.
In large industrial centres men like Priestley are the best of educators.
They are true 'merchants of light 1 , if we may borrow a phrase from that
New Atlantis which foreshadows so closely, in some important respects, the
purposes of your own foundation. And since Priestley's day there have never
been wanting among the citizens of Leeds other members of your body who
have not merely advanced natural science by special research but have spared
no effort to encourage learning in all its many branches. Not the least
active among the founders of our University have been Fellows of the Royal
Society who have not allowed the claims of particular investigations to blind
them to the wide range and essential unity of human knowledge.

BRITISH ACADEMY, LONDON

THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY OF LONDON.
We, the President, late Presidents, Council, and Fellows of the BRITISH
ACADEMY, desire to offer to the President, Council, and Fellows of the Royal
Society our cordial congratulations on the completion of the two hundred and
fiftieth year of its illustrious career. On this memorable occasion we approach
you with feelings of special attachment and confidence, inasmuch as our
Academy was, at a still recent date, founded with the co-operation and good-
will of your august Society, and we take pride in the thought that we may
almost regard our own Body as the offshoot of an historic Institution which
has flourished through so long a period of the national life. The Royal
Society had its beginnings in troublous times, when the proud legend
inscribed on the Society's seal found in very deed a wide application ; but at
no time has it been other than true to the high and arduous ends to which its
labours have from the first been devoted, or ceased from the pursuit and

CELEBRATION ADDRESSES 97

service of Truth. One of the earliest of the Associations founded in any
European country 'for promoting Natural Knowledge', it has extended its
investigations, so as to comprehend all the Physical as well as Mathematical
Sciences, and the roll of its Presidents, Secretaries, and of successive generations
of its Fellows, as well as of its Medallists, covers the entire range of modern
scientific progress. The ' Invisible College ' of the years preceding the Grant
of the Society's first Charter, which it commemorates to-day, has long since
established its leading position among the chief agencies in the advancement of
* Natural Knowledge ' throughout the world. Nor can we forget that the list
of its Officers and Fellows includes many names notable in the annals of British
Letters, and in the history of those Studies which have of late found particular
representation among the members of our own Body. Of the long and varied
labours of the Royal Society a record of monumental completeness is presented
in its Transactions, extending over very nearly the whole of the two hundred
and fifty years of its strenuous existence. To the work thus unintermittently
carried on by the Society has been added its faithful and fruitful administration
of the important trusts committed to it by the Government of the Country,
and through other Benefactions, as well as its wise distribution of the Annual
Grants made to it, and its judicious award of Distinctions marking great
achievements in original Scientific Investigation. All these high and onerous
functions have been performed by the Royal Society in a spirit of self-devotion
and with a fullness of success which entitle it to the grateful acknowledge-
ments of a long series of generations, including the present of which we form
part. With the sincere expression, on the present great occasion, of this
widespread and well-merited recognition, the British Academy, in a spirit of
faithful and grateful homage, desires most cordially to associate itself

BRITISH MUSEUM, LONDON

To THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY. THE
TRUSTEES OF THE BRITISH MUSEUM desire to offer to you their cordial con-
gratulations on the occasion of the two hundred and fiftieth Anniversary of
the foundation of your Society. Few institutions for the advancement of
natural knowledge can claim an existence of equal length ; none can boast
a longer list of services to humanity than that which stands to the credit of

98 THE ROYAL SOCIETY

the Royal Society and its Fellows. A Corporation such as yours, which
includes within its ranks all the most eminent representatives of every branch
of natural knowledge within the British Dominions, which commands the
confidence of the nation and receives the support of the Government, can
direct and co-ordinate effort, can encourage enterprise, can reward achievement,
and thereby can promote the advance and welfare of scientific investigation
with a power altogether outside the reach of individuals or of special societies.
The Royal Society is one of the glories of England and the Empire ; and all
Englishmen are glad to join in celebrating this landmark in its long career of
usefulness. The Trustees of the British Museum feel that they have a special
claim to approach you on this occasion and to share in your rejoicings. The
British Museum owes its origin to a munificent bequest from a Fellow and
President of the Royal Society, Sir Hans Sloane ; and the Act of Incorpora-
tion, by which it was founded in 1753, ordains that among the official
Trustees of the Museum shall always be the President of the Royal Society
for the time being. Thus, throughout its whole existence, the British
Museum has had the advantage of the counsel, and has enjoyed the support,
of every President of your Society ; and not least would the Trustees grate-
fully acknowledge the assistance they have received from the distinguished
man of science who now holds that high and enviable post. The interests of
the British Museum are closely intertwined with the interests of science. The
Museum, in its Library and its Natural History Departments, provides the
materials for a vast amount of scientific research. Much of that research has
been conducted by the officers of the Museum, past and present, many of whom
have received the coveted honour of the Fellowship of your Society. It is,
therefore, with the interest that is born of close association and common
aspirations that the British Museum, in the person of its Trustees, rejoices in
the glorious past of the Royal Society, and wishes it a long and not less
glorious future.

Sealed with the Common Seal of the British Museum, 6 July, 1912.

CHEMICAL SOCIETY, LONDON

THE CHEMICAL SOCIETY TO THE PRESIDENT, COUNCIL, AND FELLOWS OF THE
ROYAL SOCIETY, Greeting. Amongst the many learned bodies represented
here to-day there is certainly none which can wish to offer you more sincere
and heartfelt congratulations than the Chemical Society. The Officers,
Council, and Fellows of our Society desire to associate themselves with you
in celebrating the two hundred and fiftieth Anniversary of the birth of
a scientific corporation which in the distinction of its history is assuredly

CELEBRATION ADDRESSES 99

second to no similar body in the World. The great army of diligent and
determined workers who are united by the solemn covenant to extend Man's
knowledge of Nature look with reverence and gratitude on the Society which,
during two and a half centuries, has kept alive in these Islands the sacred fire
of Research, and has included within its Fellowship men whose names and
achievements are amongst the most imperishable glories of the human race.
We desire to take this opportunity of expressing, however imperfectly, our
indebtedness to the Society of Boyle, of Cavendish, of Priestley, of Dalton,
and of Davy, and we are proud to remember that these early masters of our
Science, by the stimulus which their investigations gave to the growth of
Chemical Knowledge, led to the origin of our Society by a natural process of
gemmation from your body. It is, therefore, in the capacity of children, and
as an act of filial piety, that we desire to offer to you, our parents, dutiful
felicitations to-day. We would take this opportunity again of gladly and
freely acknowledging before all men that whatever success our own Society
may have achieved, whatever may be the dignity to which we have attained,
and whatever service to Science and to Mankind we may have been privileged
to perform, we largely owe to the inspiration which our founders drew from
the magnificent traditions of the Royal Society. This quickening influence
has been and, we trust, may long be maintained by a close association with
you, by the community of Fellowship which exists between your Society and
ours, and by the kindred ideals and aspirations which animate us both.
Signed on behalf of the Chemical Society:

GEOLOGICAL SURVEY OF GREAT BRITAIN AND MUSEUM OF
PRACTICAL GEOLOGY, LONDON

ADDRESS OF THE GEOLOGICAL SURVEY OF GREAT BRITAIN AND THE MUSEUM
OF PRACTICAL GEOLOGY TO THE ROYAL SOCIETY OF LONDON. The Geological
Survey of Great Britain and the Museum of Practical Geology desire to take
their part in the congratulatiops which are being offered by the whole civilized
world to the Royal Society of London on the attainment of its two hundred
and fiftieth Anniversary. To the influence of the Society in carrying out its
vocation of improving Natural Knowledge, the growth of the science of
Geology was chiefly due for nearly a century and a half, and though now for
upwards of a hundred years geologists have found other homes, they can never
forget that the Royal Society is the parent of all scientific institutions in the
British Dominions. The Geological Survey and Museum are proud to
remember that all their Directors and many other members of their staff have
been Fellows of the Royal Society, and more especially that a former Director
General now occupies the Presidential Chair. Being well aware of the great
work performed by the Society not only in original research in every branch
of science but in advising the State on scientific matters, in administering
funds for the furtherance of research, and in investigations leading to the
improvement of man's position upon the earth, it is the fervent wish of these
Institutions that the Royal Society of London may long continue its eminently
distinguished and useful career.

associated with Academies, Learned Societies, and all Scientific Institutions in
rejoicing that the Royal Society which justly takes precedence as the parent
of all our Scientific Societies, has with such marked success upheld the world-
wide prestige of Science generally, and that throughout the two and a half
centuries of its existence the great objects of its founders have been faithfully
maintained to the honour of this country, and to the everlasting benefit of the
cause of civilization and humanity at large. In the domain of Chemistry, no
less than in other branches of Science, the Royal Society has fostered the

102 THE ROYAL SOCIETY

progress of Learning and Research. The Institute recalls with pride that
from its foundation in 1877 its Register has borne the names of no less than
106 Fellows of the Royal Society, while at the present time 48 Fellows of the
Institute enjoy that distinction. It is the earnest hope of the Institute that
the Royal Society may continue its career with undiminished vigour and
success and that the great traditions of its past history may be carried on by
future generations of its Fellows.

To THE PRESIDENT AND COUNCIL OF THE ROYAL SOCIETY OF LONDON
Greeting. The President and Council of the INSTITUTION OF ELECTRICAL
ENGINEERS offer their congratulations to the Royal Society on the completion
of the two hundred and fiftieth year of its existence. They are happy to
recall how much the Royal Society has done since the days of Robert Boyle
and Francis Hauksbee to promote the discovery of electrical phenomena and
of the laws of electricity and magnetism. They will ever remember the
additions to electrical knowledge due to Sir Isaac Newton, Stephen Gray,
Benjamin Franklin, Joseph Priestley, Abraham Bennet, Sir Humphry Davy,
Michael Faraday, John Frederick Daniell, Sir William Grove, Sir Francis
Ronalds, James Prescott Joule, Sir Charles Wheatstone, John Tyndall,
Latimer Clarke, David Edward Hughes, Lord Kelvin, James Clerk Maxwell,
John Hopkinson, George Francis FitzGerald, William Edward Ayrton, and
other Fellows of the Royal Society. They express the hope that the Royal
Society may enjoy unbroken prosperity, and may continue to promote the
progress of electrical science.

MATHEMATICAL SOCIETY, LONDON

THE LONDON MATHEMATICAL SOCIETY, of whose duty it is part to elaborate
the instrument without which all pursuit of Natural Knowledge must finally
be futile, desires to offer humble congratulations on the attainment of her
two hundred and fiftieth Anniversary to the Royal Society. That this
Society may ever continue to be imbued with the reverent and enthusiastic
desire to unravel the secrets of Nature which has characterized all her most
distinguished Fellows, and may ever hold herself in readiness, untrammelled
by any too intimate relations with other institutions, to take her rightful
place in succeeding times of Renaissance, is the prayer of all the special
societies who own her pre-eminence. On behalf of the London Mathematical
Society :

MERCERS' COMPANY, LONDON

To THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY. THE
MERCERS^ COMPANY OF LONDON desire to offer to you the President, Council, and
Fellows of the Royal Society their sincere congratulations on the occurrence
of the 250th Anniversary of the incorporation of your Society, whose history
from its commencement has been an uninterrupted and glorious succession
of conquests over Nature, conquests differing from other conquests in that they

105

have been achieved, not by resistance to Nature, but by an ever increasing
knowledge of and obedience to her laws. It is a further subject for
congratulation that the true method by which these results have been
achieved, the method of experiment and test, which was from the first laid
down by your Society, was truly laid, and has since been universally acknow-
ledged. We acknowledge also the large share which, on a survey of your
successes, must be attributed to the principle represented by the words which
you have adopted as your motto and have so greatly fortified in action, the
principle of the independence of the human intellect. We acknowledge it with
the more gratitude, since in supporting that principle you have conferred
benefits on mankind not limited to the particular subjects which you have
made more especially your own. We know, from the account which has been
preserved, the ideas which actuated the founders of your Society, and it is very
fitting that we of the present day, who can judge by the event the value of
those ideas, should join with you in celebrating, and render our respectful
homage to, the memory of those gifted men who formulated the principles and
laid down the lines of your work, though they could only prophetically foresee
the grandeur of the results to follow. May the Royal Society long continue
its glorious career to the increase of true knowledge, the honour of our nation,
and the welfare and happiness of the whole human race.

PHYSICAL SOCIETY, LONDON

To THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY. Many
illustrious names have been inscribed on the roll of the Royal Society during
the 250 years which have elapsed since its foundation ; but none have added
a greater lustre to the fame of the Society and to the glory of their country
than those of the men who devoted themselves to the study of Physics.
Newton firmly planted the Tree of Science, Young, Joule, Faraday, Maxwell,
Stokes, and Lord Kelvin have spread its branches in many directions. May
we, therefore, a young Society specially devoted to the study of Physics pay
our warm tribute of regard and affection to the parent body whose members
have laid the foundation on which we are trying to build ! May the record
of the Royal Society be as glorious in the future as it has been in the past,
and may she continue to possess the confidence and admiration of all who seek
the advancement of Natural Knowledge ! On behalf of the PHYSICAL SOCIETY

To THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY OF LONDON.
We, the President, Council, and Fellows of the ROYAL ANTHROPOLOGICAL
INSTITUTE OF GREAT BRITAIN AND IRELAND, desire to offer to you our hearty
congratulations on the occasion of the completion of the two hundred and
fiftieth year of your glorious history. Your Society has during that long
period been the centre of scientific thought, the home of the most illustrious
workers and discoverers in science, the representative throughout the world

CELEBRATION ADDRESSES 107

of British scientific research and the constant and trusted adviser and almoner
of the Crown and the Government of the country in respect of all matters
relating to the progress of Science. Our Institute has less than seventy years 1
record to look back upon, for the Ethnological Society of London, which forms
part of it, was founded in 1843, and the Anthropological Society of London,
which forms the other part of it, in 1863. The two Societies were combined in
1871, and it is to one who conferred lustre on your Society, our then President,
Thomas Henry Huxley, that that happy combination was due. We have
owed much to other great men who, belonging to your body, have devoted
themselves especially to the work of Anthropological Science, and have
presided over our Institute. Among these are George Busk, Francis Galton,
John Evans, John Beddoe, Augustus Franks, Augustus Pitt-Rivers, Daniel
Cunningham, and others who are departed, as well as Lord Avebury, Alexan-
der Macalister, Edward Burnet Tylor, and other distinguished members of
your body who happily remain with us. It is to one of the ornaments of your
Society Charles Darwin that the science of Anthropology owes its most
powerful inspiration. The Origin of Species and the Descent of Man
gave a new impulse and direction to the students of our science and formed
for them a fresh starting-point for laborious and fruitful investigation. We
have for many years felt the assured conviction that your body, as the
acknowledged leaders of scientific thought, had the most complete sympathy
with our work ; that you viewed the growing development of it with cordial
satisfaction ; and that you had thus contributed much towards its successful
prosecution. It is accordingly with a special feeling of gratification that we
have deputed our President, Dr. A. P. MAUDSLA,Y, to be our representative at
the Celebration of your auspicious Anniversary and to present to you in our
name this our Address of Congratulation.

ALFRED P. MAUDSLAY.

ROYAL ASTRONOMICAL SOCIETY, LONDON

WE, the President, Vice-Presidents, and Council of the ROYAL ASTRONOMICAL
SOCIETY, desire to offer our most hearty congratulations to the Royal Society on
the celebration of the 250th Anniversary of its foundation. We would testify
to the unceasing efforts of the Royal Society to promote the advancement of
Natural Knowledge, which have eminently contributed to the present remark-
able development of the sciences and their application to technical and
industrial arts. Particularly do we desire to acknowledge the beneficial
influence of the Royal Society on the study of Astronomy evidenced by the
large number of important memoirs on Astronomical Science found in its
publications. We note with pride the long roll of distinguished Astronomers

108 THE ROYAL SOCIETY

who have been Fellows of the Society ; and we are mindful that it was the
extensive progress of Astronomy made in Great Britain under the encourage-
ment of the Royal Society, which led to the formation of the Royal Astro-
nomical Society. We are confident that the Royal Society will in the future,
as in the past, continue to exercise the same fostering and effective influence
upon the progress and development of all branches of Natural Knowledge.

ROYAL GEOGRAPHICAL SOCIETY, LONDON

To THE PRESIDENT AND COUNCIL OF THE ROYAL SOCIETY, FROM THE PRESIDENT
AND COUNCIL OF THE ROYAL GEOGRAPHICAL SOCIETY. Gentlemen, On behalf
of the Council of the Royal Geographical Society, and as representing the
Fellows, I desire to convey to you our warmest congratulations on the occasion
of the celebration of the 250th Anniversary of the foundation of your Society.
It would be superfluous for me to point out the claims which the Royal
Society possesses upon the admiration and gratitude of all who have the
interests of scientific progress at heart. Through long years it was the only
Institution in this country devoted to the encouragement and publication of the
results of scientific research on purely disinterested lines, and without any hope
of reward, except the satisfaction which follows the successful search for truth.
The most illustrious names in all departments of Science have been connected
with the Royal Society from its foundation. From the very first every serious
research into any of the many aspects of the universe was welcomed by the
Society, and the results were impartially considered. In time, and largely due
to the action of the Royal Society, this work of scientific research became so
multifarious that other Societies grew up alongside the parent Society, and
co-operated in the common object of seeking after the truth, and attempting
to interpret the phenomena of the universe. In past generations the subject
with which the Society is directly concerned had its fair share of attention at
the hands of the Royal Society, many of whose Fellows were specialists in
Geography ; and the influence and example of the Royal Society have not been
without their effect in inducing British geographers to apply scientific methods
in an ever increasing degree to their own department of research. In
pursuing its work the Royal Society has rendered eminent services to the
Empire and to the world, and we confidently hope that in the future it will
continue to occupy the commanding position in Science which it has attained
in the past. On behalf of the Council and Fellows of the Royal Geographical
Society, I am, Gentlemen, Your obedient servant,

To THE ROYAL SOCIETY, LONDON. WE, THE PRESIDENT AND COUNCIL OF THE
ROYAL METEOROLOGICAL SOCIETY, desire to offer to the Royal Society our sincere
congratulations on the occasion of the two hundred and fiftieth Anniversary of
its foundation. We are deeply sensible of the pre-eminent position which the
Royal Society has always held in the promotion of natural knowledge, and of
the beneficial influence it has exerted upon the advancement of learning and
also upon the scientific development of the technical and industrial arts, by its
unceasing efforts. We recognize with especial satisfaction the support which
the Royal Society has afforded to the science of Meteorology, as exemplified
particularly in the labours of the Meteorological Committee. Many names
eminent in meteorological science occur in the Roll of Fellowship of the
Royal Society, and the published records of the Society contain numerous
contributions of outstanding importance to our knowledge of the mechanics
and physics of the atmosphere. In congratulating the Royal Society upon
a long and brilliant record of past achievement we are assured that it will
continue in the future to take an equally important part in the progress of
all branches of science.

ROYAL SOCIETY OF ARTS, LONDON

THE ROYAL SOCIETY FOR THE ENCOURAGEMENT OF ARTS, MANUFACTURES,
AND COMMERCE welcomes the opportunity which has been afforded to it of
offering its warm congratulations and best wishes to the Royal Society on
the 250th Anniversary of its foundation. Among the many services which
the Royal Society has rendered to this country and to Science in general,
one not the least has been that in proportion as the increase of knowledge
has rendered necessary special and separate study of each branch of in-
vestigation, the Society has been instrumental in the formation of fresh
Associations for this purpose, while itself maintaining a general interest in
the whole field of progress and discovery. The Society of Arts, in whose
foundation a century and a half ago several Fellows of the Royal Society
took a prominent part, has from its commencement looked to the Royal
Society as the parent of such Associations in this country, no less than the
model for similar combinations abroad, and congratulates itself on the close
connexion between the two Societies, which has been maintained throughout
its existence by the presence in its ranks of many distinguished Fellows of
the Royal Society. The Council have had pleasure in deputing their CHAIRMAN
to represent them among the distinguished crowd of Delegates who have
come from all countries of the world to take part in the celebration of this
auspicious Anniversary, and they desire to express their earnest hope that
the future may have in store for the first and greatest of English Scientific
Societies achievements no less illustrious and beneficial to mankind than those
which are recorded in its past history. Sealed with the Seal of the Royal
Society for the Encouragement of Arts, Manufactures, and Commerce in the
presence of .

CELEBRATION ADDRESSES 111

ROYAL SOCIETY OF MEDICINE, LONDON

THE ROYAL SOCIETY OF MEDICINE. The President, Council, and Fellows
of the Royal Society of Medicine very heartily congratulate the President,
Council, and Fellows of the Royal Society on the completion of two hundred
and fifty years spent in the execution of the very important duties with which
it is entrusted. A Society which has for its object the improvement of the
Art and Science of Medicine in all its branches, towards which improvement
the advancement in knowledge in various other Sciences so largely contributes,
cannot but take the warmest interest in the continued prosperity and use-
fulness of the Royal Society, especially as there were among the original
members of that Society several Fellows of the Royal College of Physicians
of London, and as moreover several of its Presidents have been Fellows
either of that College or of the Royal College of Surgeons of England. In
former times when the power of Analysis had outrun the means of obtaining
knowledge, natural Philosophy and Metaphysics and the analysis of Sense
and the analysis of Thought were hopelessly confused by the attempt to
solve them, not through an appeal to facts, but by the help of general
theories respecting the nature of the Universe. In the philosophy of
Antiquity the meaning of the word 'Science' could scarcely be explained
to students, except from the mathematical sciences, which alone offered the
type of Universality and Certainty. Geometry was regarded as the pro-
paedeutic to philosophy. Somewhat of this view perhaps lingered at the
time when those who afterwards gave birth to the Royal Society had 'a
designe of founding a Colledge for the promoting of Physico-Mathematicall-
Experimentall Learning '. But the Royal Society having arisen out of the
'Invisible College 1 of which Boyle the disciple of Francis Bacon (both of
imperishable fame) speaks in sundry letters, having been granted a Charter
on July 15th, 1662, by Charles II, mathematical pupil of Hobbes, and
having adopted as its title the name first applied to it by the celebrated
diarist Evelyn directed its inquiries, particularly, to what was then called
the ' New Philosophy ' or ' Experimental Philosophy ' ' for the improving of
natural knowledge by experiments \ True to its origin and history, the
Royal Society still elects Princes of the Blood, and persons selected by the
Council from among men distinguished in walks of life other than Science ;
whilst by the restrictions made during the presidency of Sir Joseph Banks,
and subsequently, the number of Candidates recommended for election has
been limited to fifteen annually. Concurrently with this restriction of the
Fellowship, Science has grown enormously ; and as a consequence, other
Scientific Societies have been established, some under the auspices of several
Fellows of the Royal Society and by Royal Charter, some independently of
either of these advantages, but all active in the promotion of special branches

112 THE ROYAL SOCIETY

of Science. The Royal Society is 144 years younger than the Royal
College of Physicians of London, but it is the oldest exclusively scientific
body in Great Britain, and one of the oldest in Europe. That it may
continue in the successful performance of its various functions as the promoter
of scientific investigations and researches, as the adviser of the Government
in connexion with national scientific works, and as the administrator of
Government grants and trust funds for experiments and for the publication
not only of its own invaluable Transactions and Proceedings but also of
scientific papers issued through other channels, is the earnest wish of the
Royal Society of Medicine, which shares with other learned bodies the honour
and special pleasure of taking part in the festivities of this Commemoration.

ROYAL STATISTICAL SOCIETY, LONDON

To THE PRESIDENT, COUNCIL, AND FELLOWS OF THE ROYAL SOCIETY. WE, THE
PRESIDENT AND COUNCIL, representing the general body of Fellows of THE
ROYAL STATISTICAL SOCIETY, desire to present to the President, Council, and
Fellows of the Royal Society on the occasion of the two hundred and fiftieth
Anniversary of its foundation, our sincere congratulations and greetings.
We are proud to claim association with your illustrious Society, not only
because in the pursuit of exact knowledge we look to you for guidance and
inspiration, but also because since the earliest days the Royal Statistical
' Society has received the active support of many who are eminent in Science.
We recall with satisfaction that among the great names which adorn your
roll are included those of many of our Presidents, while other Fellows of our
Society intimately associated with our aims and activities, have added to
their distinction as Statisticians the lustre of the Fellowship of the Royal
Society. Among our Presidents the names of Lord John Russell, Lord
Houghton, William Newmarch, Dr. William Farr, Dr. Guy, Lord Goschen,
Sir Robert Giffen, Lord Avebury are prominent ; while our list of Treasurers
includes Henry Hallam and George Richardson Porter. It is of interest also
to record that Charles Richard Weld, the historian of the Royal Society, was
at one time Assistant Secretary to the Royal Statistical Society. On the
maintenance of your high traditions and the continuance of your labours
depend in a large degree the future welfare and greatness of our nation.
Now more than ever must your researches, by their breadth, by their
penetration, by their originality, give an impulse to the force and variety
of our national life. Great, however, as is your national mission, there is
a greater still ; for Science recognizes no geographical frontiers nor is
national advancement alone its incentive. Your high ideals touch the
welfare of all mankind, and your labours are illumined by the whole

firmament of Knowledge. It is because, in our more modest sphere of work,
we too are guided by the same standards and inspired by the same ideals
that we offer our sincere congratulations on this memorable occasion.

may continue to prosper, and may always maintain that pre-eminent position
which is the fitting reward of its labours. Signed on behalf of the Council :

ASHMOLEAN NATURAL HlSTORY SOCIETY OF OXFORDSHIRE

THE ASHMOLEAN NATURAL HISTORY SOCIETY OF OXFORDSHIRE sends heartiest
congratulations to the Royal Society on the celebration of the 250th
Anniversary of its foundation. It begs to express its profound admiration
for the great part the Royal Society has played in the extensive development
of Natural Knowledge, and in the enormous advancement of the beneficial and
industrial Arts, during those 250 years, and thanks the Royal Society for
the stimulus and encouragement it has always afforded to other Societies,
throughout the Empire, by its splendid example in the field of research. For
these reasons the Ashmolean Natural History Society of Oxfordshire, thus
named in memory of Elias Ashmole, one of the earliest Fellows of the Royal
Society, desires herewith to offer its humble homage and greeting.

ARTHUR A. RAMBAUT, President and Delegate.

To THE PRESIDENT, COUNCIL, AND MEMBERS OF THE ROYAL SOCIETY. THE
PRESIDENT AND COUNCIL OF THE SOCIETY OF CHEMICAL INDUSTRY offer to the
Royal Society their most hearty congratulations on the attainment of the two
hundred and fiftieth Anniversary of its foundation and have nominated to

i 2

116 THE ROYAL SOCIETY

represent them on this happy occasion RUDOLPH MESSEL, their President. At
no time in the history of experimental science has there been any hard and fast
line dividing science from its applications, and the President and Council of
the Society of Chemical Industry recognize with pride that among the Fellows
of the Royal Society have been found some of the most brilliant examples the
world has seen of the genius which, while it seeks and grasps the highest
generalizations, is at the same time intensely alive to the applications of
science in arts and manufactures. As the oldest chartered scientific society in
this country and the mother of many daughter societies, the Royal Society
rouses the sympathy and admiration of all followers of applied science
throughout the world. The Society of Chemical Industry cannot forget that
it owed much of its early success to the timely support of Fellows of the Royal
Society : the Right Honourable Sir Henry Roscoe, its first President ; Sir
Frederick Abel, Sir Lowthian Bell, Sir William Perkin, Sir William Siemens,
Dr. Angus Smith, Mr. Walter Weldon, Prof. A. W. Williamson, and Dr.
James Young, its first Vice-Presidents ; and Capt. W. de W. Abney, Sir
William Crookes, Dr. Peter Griess, and Dr. Hermann Sprengel, Members of its
first Council. When the Society of Chemical Industry opened its doors to men
of every country and every race, the Royal Society at once welcomed this
manifestation of the brotherhood of Science, and marked its appreciation of the
great importance of such international exchanges of courtesy and scientific
opinion by the new departure of a reception to the Society and its members
who had come across the sea. In industrial production the gain of one nation
may be the loss of another, but the victories of science stand alone in that
there is no enemy to vanquish but ignorance, and its conquests are for the gain
and enrichment of the whole human race. The increased power over nature
won by the work of Davy and Faraday, of Rumford, and of Rutherford gives
no exclusive gain to any one country. The Royal Society and the Society
of Chemical Industry have a common object in improving and increasing
natural knowledge, and the future condition of mankind, both intellectually
and materially, depends upon the growth and activity of scientific Societies.
The organized and systematic application of science to industry is still far
from complete. The Society of Chemical Industry looks to the Royal Society
to continue to bestow upon its work the interest and encouragement which
have been so fully granted in the past. In wishing for the Royal Society
continued and increasing prosperity, the President and Council trust that the
cordial relations existing between the Societies may be maintained and result
in a more extended co-operation.

THOMAS TYRER, Treasurer.

CELEBKATION ADDRESSES 119

ROYAL SOCIETY OF EDINBURGH

To THE ROYAL SOCIETY OF LONDON. THE PRESIDENT AND FELLOWS OF THE
ROYAL SOCIETY OF EDINBURGH desire to offer their congratulations to the
Royal Society of London upon the attainment of the two hundred and
fiftieth Anniversary of its foundation. Founded for the purpose of ' further
promoting by the authority of experiments the science of natural things and
of useful arts', the Royal Society of London has with increasing zeal and
power continued to fulfil its high calling, and commands in the world of
scientific endeavour a position peculiarly its own. The Royal Society of
Edinburgh recalls with pride and satisfaction that since its own foundation in
1783 there has always existed between the two Societies a close association,
based not only on community of aim and interests, but in great measure
also upon community of membership. Scientific men of eminence have served
on the Councils, and contributed to the publications", of both Societies ;
and each Society can claim the late Lord Kelvin as one of the most renowned
of its Presidents. At this time the personal connexion is happily exemplified
by the fact that the distinguished President of the Royal Society of London
has been a Fellow of the Royal Society of Edinburgh for fully half a century.
May the important work which the Royal Society of London has achieved
in the past be continued and extended, during many centuries to come, to
the furtherance of natural knowledge and the progress of humanity.

WM. TURNER, President.

ROYAL PHILOSOPHICAL SOCIETY OF GLASGOW

THE ROYAL PHILOSOPHICAL SOCIETY OF GLASGOW TO THE ROYAL SOCIETY OF
LONDON FOR THE ADVANCEMENT OF NATURAL KNOWLEDGE. We, the Members
of the Royal Philosophical Society of Glasgow, desire to express our gratifica-
tion at the courteous invitation to take part in celebrating the two hundred
and fiftieth Anniversary of the foundation of the Royal Society of London,
and our heartiest congratulations on the uninterrupted and pre-eminently
fruitful activity of the Society over a period of such duration. Scientific
Societies and Learned Bodies of all nations are bound and indebted in many
ways to the Royal Society ; for leadership in scientific thought, for encour-
agement of research, and for an unsparing hand in the dissemination of
knowledge. Since its inception the history of the progress of the Royal
Society has been largely the history of the advancement of science : the long

120 THE ROYAL SOCIETY

Roll of its Fellows bears the names of almost all the illustrious men of two
and a half centuries. Many of these we can recall whose names have adorned
our own Roll, and we cherish with peculiar satisfaction the recollection that
the late Lord Kelvin, during wellnigh sixty years, gave liberally of the
offspring of his great genius to forward the interests of both societies. We
also recall with pride that on the celebration of the Centenary of our Society
in 1902 we were honoured by a cordial greeting from the Royal Society the
Mother and the Model of all the learned societies in the English-speaking
world. It is our earnest hope that the Royal Society may long continue,
with ever fresh ardour and increasing power, to carry on its great work for
the advancement of knowledge.

Signed on behalf of the Members of the Royal Philosophical Society of
Glasgow, this second day of July., Nineteen hundred and twelve.

ROYAL DUBLIN SOCIETY

THE ROYAL DUBLIN SOCIETY TO THE ROYAL SOCIETY OF LONDON Greeting.
The President and Council of the ROYAL DUBLIN SOCIETY heartily join in
congratulating the Royal Society of London on the attainment of the two
hundred and fiftieth Anniversary of its foundation. Great has been the
progress of science since the Society under Royal auspices undertook the task
of improving natural knowledge, and the Fellows may well look with pride
upon the conspicuous part they have taken in winning from Nature her well-
guarded secrets. We earnestly hope that the Royal Society may continue its
beneficent labours with increasing success, ever widening the bounds of know-
ledge and extending man's control over Nature.

Given under our Common Seal at Leinster House* Dublin, this first day of
August, 1912.

HOWARD GRUBB, Vice-President.

QUEEN'S UNIVERSITY OF BELFAST

To THE PRESIDENT AND FELLOWS OF THE ROYAL SOCIETY OF LONDON. WE,
THE CHANCELLOR AND MEMBERS OF THE QUEEN'S UNIVERSITY OF BELFAST, desire
to convey our congratulations on the occasion of this your Fifth Jubilee, and,
with our elders in learning, to acknowledge the blessings which your example
and generous endeavour have bestowed upon the commonwealth of Science.
The Virtuosi of Gresham College planned with confidence in their purpose and
in their successors. Within five years the poet's compliment that your Society
was ' worthy a history ' found proof in the memorable record of your first
efforts 'to increase the Powers of all Mankind'. At this remove it is our
privilege to do honour to a great tradition, and to see in that tradition less
the pride of accomplishment than the continuing promise of ' ransom to the
mind of man '.

Signed in name of the University, on the fifteenth day of July , one thousand
nine hundred and twelve.
