MEMOIR,

&c. &c.

The following slight Memoir of the Life of the late Dr. Young was drawn

up, from some short memoranda of his own writing in the possession of

a near connexion, by one who had the advantage of long and intimate

acquaintance with that distinguished scholar and philosopher; but who,

never having been engaged in the pursuits of accurate science, feels

himself incompetent to give more than an imperfect sketch, which he

trusts to see filled up hereafter by an abler hand.

Dr. Thomas Young, a man eminently distinguished in more departments

of literature and science than any other individual of his age and

country, was born at Milverton in Somersetshire, the 13th of June,

1773. He was the eldest of ten children of Mr. Thomas Young of that

place, and his mother was a niece of Doctor Richard Brocklesby, a

physician of eminence in the metropolis, who was well known both from

his connexion with the first literary societies, and with the highest

political circles of the times in which he lived.

His parents were both of them of the society of Quakers, and of the

strictest of a sect, whose fundamental principle it is, that the

perception of what is right or wrong, to its minutest ramifications, is

to be looked for in the immediate influence of a Supreme intelligence,

and that therefore the individual is to act upon this, lead where it

may, and compromise nothing. To the best of these early impressions he

was accustomed in after-life to attribute, in some degree, the power

he so eminently possessed of an imperturbable resolution to effect any

object on which he was engaged, which he brought to bear on every thing

he undertook, and by which he was enabled to work out his own education

almost from infancy, with little comparative assistance or direction

from others.

From a very early period Dr. Young was chiefly an inmate in the

family of his maternal grandfather, Mr. Robert Davies, of Minehead;

a gentleman who amidst mercantile avocations, though no very deep or

accurate scholar, had cultivated a taste for classical literature,

which it was his earnest endeavour to impress upon the mind of his

grandson. It is stated that whilst domesticated with him, he had learnt

to read with fluency when he was two years old, and that soon after

this, in the intervals of his attendance on a village schoolmistress,

he was made to commit to memory a number of English poems, and even

some Latin ones, the words of which he retained without difficulty,

although at the time unacquainted with their meaning.

Before he was six years old, he attended the seminary of a dissenting

minister, and went afterwards to a school at Bristol, where he remained

about a year and a half, and where the deficiency of the instructor

appears to have advanced the studies of the pupil, as he here first

became his own teacher, and had by himself studied the last pages of

the books used, before he had reached the middle under the eye of the

master.

His father had a neighbour, a man of great ingenuity, by profession a

land surveyor and land steward; and in his office, during his holidays,

he was indulged with the use of mathematical and philosophical

instruments, together with the perusal of three volumes of a Dictionary

of Arts and Sciences, which he also found there. These were to him

sources of instruction and delight of which he seemed never to weary,

and which, thus accidentally thrown in his way, had probably no small

influence on the issues of his future life.

In 1782, he was sent to the school of a Mr. Thompson, at Compton, in

Dorsetshire, of whom he was always accustomed to speak with great

respect, as a person of an enlarged and liberal mind; and who,

possessed of a moderate and miscellaneous library, permitted and

encouraged his scholars to turn it to their profit; the principle which

he adopted in the course of his instructions, being to allow them a

certain degree of discretion in the employment of their time.

Here Young went through the ordinary course of Greek and Latin

Classics, together with the elementary parts of the Mathematics; and

by rising earlier and sitting up later than his companions, with the

assistance of a schoolfellow who had some French and Italian books,

he rendered himself tolerably familiar with those languages. He had

acquired, in his visits to his father’s neighbour, the art of land

surveying, and the amusement of his walks was to measure heights with a

quadrant.

The next study he undertook was Botany, and for the sake of examining

the plants which he gathered, he attempted the construction of a

microscope from the descriptions of Benjamin Martin. This led him to

Optics; but in order to make his microscope, he found it necessary to

procure a lathe. Every thing then gave way to a passion for turning,

and science was forgotten for the acquirement of manual dexterity;

until falling upon a demonstration in Martin which exhibited some

fluxional symbols, he was never satisfied till he had read and mastered

a short introduction to the doctrine of Fluxions.

Mr. Thompson had left in his way a Hebrew Bible. He began by enabling

himself to read a few chapters, and was soon absorbed in the study

of the principal Oriental languages. At the age of fourteen, when he

quitted Mr. Thompson’s school, he was thus more or less versed in

Greek, Latin, French, Italian, Hebrew, Persic, and Arabic; and in

forming the characters of those languages, he had already acquired

much of the beauty and accuracy of penmanship which was afterwards so

remarkable in his copies of Greek compositions, as well as of those

subjects connected with the literature of ancient Egypt.

In 1787, the friends of Dr. Young were beginning to think seriously of

the line in life which might be most advantageously taken by a youth of

such extraordinary promise. When at the house of one of his relations

he accidentally met a connexion of Mr. David Barclay, of Youngsbury,

in Hertfordshire, who was then wishing to form an arrangement for

the education of his grandson, and through the intervention of Sir

William Watson, it was agreed that Dr. Young and the grandson of Mr.

Barclay should pursue their studies together, under a private tutor,

in Mr. Barclay’s house. The tutor who was engaged, found a situation

of greater permanence, and never came; so that two boys being left

together, whose ages differed only about a year and a half, Young, then

little more than fourteen, took upon himself, provisionally, the office

of preceptor. They were afterwards joined by a gentleman who was then

in progress of perfecting himself in the higher branches of classical

attainment, of somewhat maturer years, and who has since been known to

the world as the author of the “Calligraphia Græca.” But Dr. Young did

not relinquish the task which he had previously undertaken, and already

far advanced beyond the limits of ordinary scholastic attainment, was

the principal director of the studies of the whole party.

When about the age of fourteen, he was attacked by symptoms of what

was feared to be incipient consumption. But under the attendance of

his uncle Dr. Brocklesby, and Baron Dimsdale, he recovered his health,

without suffering any ultimate inconvenience, and was enabled for the

most part, to pursue his labours through the whole duration of his

indisposition, merely relieving his attention by what, to him, stood in

the place of repose—a course of Greek reading in such authors as amused

the weariness of his confinement.

In the five years between 1787 and 1792, residing during the summers

in Hertfordshire, and for some months of the winter in London, with

no other assistance than that of a few occasional masters in the

latter place, he had rendered himself singularly familiar with the

great poets and philosophers of antiquity, keeping ample notes of his

daily studies. Of the various and conflicting opinions of the ancient

philosophers he had drawn up a most admirable analysis; and as his

reading was not merely the gaining words and phrases, and the minuter

distinctions of dialects, but was invariably also directed to what was

the end and object of the works he laboured through, it is probable

that the train of thought into which he was led in this analysis, was

not without its effect, in somewhat mitigating his attachment to the

peculiar views of the sect amongst whom he had been born.

He had acquired a great facility in writing Latin. He composed Greek

verses which stood the test of the criticism of the first scholars of

the day, and read a good deal of the higher mathematics. His amusements

were the studies of botany and zoology, and to entomology in particular

he at that time gave great attention.

In the winters of 1790 and 1791, having prepared himself by previous

reading, he attended the lectures of Dr. Higgins in chemistry, and

began to make some simple experiments of his own on a small scale.

But he was afterwards accustomed to say, that at no period of his

life was he particularly fond of repeating experiments, or even of

very frequently attempting to originate new ones; considering that,

however necessary to the advancement of science, they demanded a great

sacrifice of time, and that when the fact was once established, that

time was better employed in considering the purposes to which it might

be applied, or the principles which it might tend to elucidate.

His uncle Dr. Brocklesby had at this time desired to receive from him

a regular report of his literary and scientific pursuits, intending

to take upon himself the supervision of his further education for the

practice of physic, which was the line he recommended him to adopt; and

having communicated some of his Greek translations to Mr. Burke and Mr.

Windham, with both of whom Dr. Brocklesby had lived in intimacy, an

acquaintance with these two distinguished persons ensued; in the course

of which, Mr. Burke was so greatly struck with the reach of his talents

and the extent of his acquirements, more particularly by his great

and accurate knowledge of the Greek language, that Dr. Young may be

considered as in no small degree indebted to the good offices of that

eminent statesman, for the extent of interest which his uncle took from

this period in his future settlement in life.

It may probably be considered that it was in these years that his

character received its developement. He was never known to relax in

any object which he had once undertaken. During the whole term of

these five years, he never was seen by any one, on any occasion, to be

ruffled in his temper. Whatever he determined on, he did. He had little

faith in any peculiar aptitude being implanted by nature for any given

pursuits. His favourite maxim was, that whatever one man had done,

another might do; that the original difference between human intellects

was much less than it was generally supposed to be; that strenuous and

persevering attention would accomplish almost any thing; and at this

season, in the confidence of youth and consciousness of his own powers,

he considered nothing which had been compassed by others beyond his

reach to achieve, nor was there any thing which he thought worthy to be

attempted, which he was not resolved to master.

This self-conducted education, in the privacy of a singularly regular

family, was not however without its disadvantages. The acquisitions he

was thus making in seclusion were great, but he was not in the way of

gaining that which is acquired insensibly in the conflict of equals in

the commerce of the world—the facility of communicating knowledge in

the form that shall be most immediately comprehended by others, and

the tact in putting it forth, that shall render its value immediately

appreciated. It was in 1791 that he made his first communications to

the press, through the Monthly Review and the Gentleman’s Magazine,

being Greek criticism, chemical theories, and remarks on botany and

entomology.

Towards the end of 1792, Dr. Young established himself in lodgings in

Westminster, in which he resided about two years, for the purpose of

pursuing his medical studies, attending the lectures of Baillie and

Cruickshank in the Hunterian school of anatomy; and he was during that

period amongst the most diligent of the pupils of St. Bartholomew’s

Hospital.

In 1793, he made a tour in the west of England, principally with a view

of studying the mineralogy of Cornwall; and about this time having

been introduced to the acquaintance of Charles Duke of Richmond, who

had long been a friend of his uncle’s, and was then Master-General

of the Ordnance, he was offered by his Grace the situation of

assistant-secretary in his house. He felt that this was an opportunity

for entering into public life which might lead to advantage and

distinction. Mr. Burke and Mr. Windham recommended him rather to

proceed to Cambridge and study the law; but after some consideration of

these conflicting proposals, he determined to adhere to the pursuits of

science, and to proceed to the practice of physic, as most congenial

both to his predilections and his habits, and to which the position

occupied by his uncle appeared to offer a natural introduction.

In this year he gave to the Royal Society his Observations on Vision,

and his Theory of the Muscularity of the Crystalline Lens of the

Eye, which became the subject of much discussion, and John Hunter

immediately laid claim to having previously made the discovery. Dr.

Young was soon afterwards elected a Fellow of the Royal Society, when

he had just completed his twenty-first year.

In the autumn of 1794 he went to Edinburgh, and there attended the

lectures of Doctors Black, Munro, and Gregory. He pursued every branch

of study in that university with his accustomed intensity, but made the

physical sciences more peculiarly the objects of his research. He now

separated himself from the Society of Quakers, and amidst his medical,

scientific, and classical labours, he determined on cultivating some of

those arts in which he considered that his early education had left

him deficient. But every thing, be its nature what it might, was with

him a science; whatever he followed, he followed scientifically. He

was extremely fond of music, and of the science of music he rendered

himself a master. He had at all times great personal activity, and in

youth he delighted in its exercise. But perhaps it may provoke a smile,

though too characteristic an anecdote to omit, that in instructing

himself in the figure of a minuet, he made it the subject of a

mathematical diagram.

Towards the close of 1795 he went to the university of Gottingen,

where he took his doctor’s degree. His extraordinary attainments,

and the almost incredible industry with which he pursued his studies

in all their variety, excited the wonder of the laborious school in

which he had now placed himself. He found their academical library

peculiarly rich in works of reference; and in composing his inaugural

dissertation, “De Corporis Humani Viribus Conservatricibus,” he left

few volumes unconsulted which had any connexion with the subject on

which he was treating.

In all periods of his life Dr. Young was entirely exempt from those

dissipations into which young persons unhappily very generally fall,

and here, as at Edinburgh, he diversified his graver studies by

cultivating skill in bodily exercises. He took lessons in horsemanship,

in which he always had great pleasure, and practised under various

masters all sorts of feats of personal agility, in which he excelled to

an extraordinary degree.

The victories of the French at this time prevented him from visiting

Italy, which he had intended to do previously to his return to England;

and unwilling to be deficient in any species of knowledge, he proceeded

to Dresden; where he spent some time for the purpose of studying the

works of Italian art in the galleries of that city, and to compare what

he saw with that which he had learnt of them from the Lectures of the

professors of Gottingen. Before returning home, he completed his stay

on the Continent by a short visit to Berlin.

Dr. Young, during his residence in Germany, had gained a very general

and accurate acquaintance with the language and literature of that

country, which he kept up throughout his life; but he remarked that he

found in Germany a love of new inventions, singularly, and somewhat

pedantically, combined with the habit of systematizing older ones, and

giving an importance to things in themselves trifling, which in his

case rather confirmed an original habit of dwelling on minutiæ more

than his subsequent experience led him to think was advantageous.

In consequence of some new regulations of the College of Physicians,

which had taken place during his residence abroad, he found himself

precluded from immediately practising as a licentiate in London; he

therefore entered himself as a fellow-commoner in Emanuel College,

Cambridge, of which Dr. Farmer was then master, who was an intimate

friend of his uncle’s. He here proceeded to take his regular degrees in

physic in that university, pursuing, during his residence, the various

studies in which he was engaged; but finding no rival in the variety of

his knowledge, and few competitors in most of its branches, he lived

with those most highly gifted, discussing subjects of science with the

professors, but not attending any of the public lectures, considering

that they were in their nature intended for a junior class of students,

and relating to branches of knowledge with which he had already made

himself acquainted.

Dr. Brocklesby died in December 1797, when the larger part of his

fortune was inherited by his nephew, Mr. Beeby; the remainder, with

his house, his books, and his pictures, was left to Dr. Young. He now

found himself in circumstances of independence, surrounded by a circle

of academical friends and associates, and formed many friendships

in distinguished and highly cultivated society, which he continued to

prize and to enjoy through life.

He had, during his residence at Cambridge, given some papers to the

Royal Society and had amused himself by contributing several essays

on philosophical and other subjects to some periodical publications;

a part of these he afterwards reprinted, but considered others of a

lighter texture than would bear the criticism of severer experience.

When his necessary residence at college was completed, Dr. Young

settled himself as a physician in London, in Welbeck-street, where he

continued to reside during twenty-five years. It was not long, however,

before he accepted the situation of Professor of Natural Philosophy in

the Royal Institution, where he was for two years colleague as lecturer

with Sir Humphrey Davy. The first volume of the Journals of the Royal

Institution and a part of the second were edited, and for the most

part composed by him. He gave two Bakerian lectures on the subjects

of Light and Colours to the Royal Society, and in 1802 he published

a Syllabus of a Course of Lectures on Natural and Experimental

Philosophy, with mathematical demonstrations of the most important

theorems in mechanics and optics; and containing the first publication

of his discovery of the general law of the Interference of Light,

being the application of a principle which has since been universally

appreciated as one of the greatest discoveries since the time of

Newton, and which has subsequently changed the whole face of Optical

science.

As a lecturer at the Royal Institution, Dr. Young was apt, in no small

degree, to pass the capacities of his audience, who at this conjuncture

were led to their attendance more as a matter of fashion, than from

a love of research, and who for the most part had little previous

knowledge. His style was compressed and laconic; he went into the

depths of science, and indeed gave more matter than it would perhaps

have been possible for persons really scientific to have followed at

the moment without considerable difficulty.

In the summer of 1802 Dr. Young accompanied the present Duke of

Richmond and his brother, Lord George Lennox, in his medical capacity,

to Rouen in Normandy, with their tutor, Mr. Vincent; and in an

excursion from thence to Paris, was first present at the discussions of

the National Institute of France, at that time attended by Napoleon;

where he made the acquaintance of several leading members of that

distinguished body, into which he himself was eventually elected. On

his return he was constituted foreign secretary to the Royal Society,

an office which he held during life, being long their senior officer,

and always one of the leading, and most efficient members of their

council.

In 1804, Dr. Young married Miss Eliza Maxwell, daughter of James

Primrose Maxwell, Esq., of Cavendish-square, who has lived to lament

his loss, after an union which was attended with uninterrupted

happiness.

At this time he resigned his office as lecturer to the Royal

Institution, it being thought by his friends that his holding it

longer would be likely to interfere with his success as a medical

practitioner. This view, as regarding his continuance in a situation

which would appear to the public to be anomalous to his profession, and

hardly compatible with its duties, was probably a just one. But in

settling in married life Dr. Young carried a deference to the supposed

feelings of the world towards those physicians who distinguished

themselves in lines of research not obviously connected with their

calling, to an excess which, in a man of his extraordinary talents

and attainments, was certainly to be lamented, and possibly even with

reference to those objects proposed to be compassed by it.

His resolution at that juncture was to confine himself for the most

part to medical pursuits, and to make himself known to the public

in no other character. But he had resolved on that which to him was

impossible. He never slackened either in his literary or philosophical

researches. He was always aiding, and always willing to be the

counsellor of any one engaged in similar investigations. He was living

in the first circles of London, amongst all who were most eminent.

The nature of his habitual avocations was necessarily well known; and

therefore in putting forth his non-medical papers, separately and

anonymously, he was making a fruitless as well as voluntary sacrifice

of the general celebrity to which he was entitled; and shrinking as

it were from the cumulative reputation which he must otherwise have

enjoyed, he waived, in some degree, the advantage which is given by a

great name towards the pursuit even of professional success.

In 1807 however, Dr. Young published his “Course of Lectures on Natural

Philosophy and the Mechanical Arts,” in two volumes quarto. This

elaborate work he stated to have been the result of the unremitting

application of five years; two having been given to the composition of

the original lectures, and three more to the compilation of the mass

of references in the second volume, to all those works to which the

student might advantageously have recourse who wished to pursue any

more minute enquiry; and to incorporating at the same time with the

Lectures, as at first given, such results as might require insertion.

The booksellers engaged in this publication failed at the moment of

its coming out, which greatly injured the immediate sale of the work;

but it was a mine to which every one has since resorted, and contained

the original hints of more things since claimed as discoveries, than

can perhaps be found in a single production of any known author. For

some years, indeed, it seemed hardly to have made its way to general

use in England, but it was so appreciated by the philosophers of the

Continent, that one of the men most distinguished for science in Europe

has been known to say, that if his library were on fire, and he could

save only one book from the conflagration, it should be the Lectures of

Dr. Young.

For sixteen successive years from the period of his marriage, Dr. Young

passed his winters in London and his summers at Worthing, having been

in 1810 appointed physician to St. George’s Hospital. In his profession

his published labours would prove him to have been of the most learned

of scientific physicians, and his judgment and acuteness were equally

great: but in the practice of medicine Dr. Young was not one of those

who were likely to win the most extended occupation amongst the

multitude. He was averse to some of the ordinary methods by which it

is acquired. He never affected an assurance which he did not feel, and

had perhaps rather a tendency to fear the injurious effects which might

eventually result from the application of powerful remedies, than to

any overweening confidence in their immediate efficacy. His treatises

bear the same impress. That on Consumption, is a most striking instance

of his assiduity in collecting all recorded facts, and his abstinence

in drawing inferences from isolated cases, or putting forth that which

he did not feel was established with certainty. Possibly he herein was

an example, that increase of knowledge does not tend to increase of

confidence, and that those whose acquirements are the greatest, meet in

the progress of their investigations with most that leads to distrust.

However it might be, his practice, though respectable, was never very

extensive.

Dr. Young afterwards published a “Syllabus of Lectures on the Elements

of the Medical Sciences,” as delivered by him at the Middlesex

Hospital, and his “Introduction to Medical literature, including a

System of Practical Nosology”—the latter a work of great labour,

forming like his Natural Philosophy, a text book of the highest

practical utility, and accompanied by a mass of references, which,

to industry and perseverance less than his, it should seem almost

impossible to have accumulated.

The Lectures, like every thing which proceeded from Dr. Young, were,

even in his own estimation, too full of matter and too much compressed

to be conveniently followed by the hearer in a course of oral

instruction. Indeed, in all things he was rather too apt to presume a

knowledge in other persons which they did not possess, and consequently

to fail in his estimate of how much of explanation was needed in

communicating the results of science to those who were comparatively

ignorant.

To the larger of these works he prefixed a “Preliminary Essay on the

Study of Physic;” in which he gives a singular picture of what, in

his opinion, is required to constitute a well-educated physician;

enumerating nearly every possible quality of which man could wish, but

of which few could hope, the attainment.

Dr. Young contributed to the Quarterly Review a variety of articles,

literary and scientific. He first engaged, at the suggestion of Mr.

George Ellis, one of his most intimate and most valued friends, to

furnish those on medical subjects to that work. But his communications

soon branched into other lines, many of them connected with the higher

departments of science, and containing the results of some of his most

laboured researches. The Review of Adelung’s Mithridates, Vol. X.

October 1813, is perhaps the most remarkable, not only from the immense

knowledge it displays of the structure of almost all languages, but as

having been the composition which first led him to the investigation of

the lost literature of ancient Egypt.

In the year 1814, Sir William Rouse Boughton had brought with him

from Egypt some fragments of Papyri, which he put into the hands

of Dr. Young; the fragment of the Rosetta stone having been about

this time deposited in the British Museum, and a correct copy of its

three inscriptions having been engraved and circulated by the Society

of Antiquaries. Dr. Young first proceeded to examine the enchorial

inscription, and afterwards the sacred characters, and after a minute

comparison of these documents, he was enabled to attach some “Remarks

on Egyptian Papyri, and on the inscription of Rosetta,” containing

an _interpretation of the principal parts of both the Egyptian

inscriptions on the pillar_; to a paper of Sir William Boughton’s,

which was published by the Society of Antiquaries in 1815, in the

eighteenth volume of the Archæologia.

Dr. Young now found he had discovered a key to the lost literature of

ancient Egypt. He had occupied himself, though without deriving from it

the assistance he had at first expected, in the study of the Coptic and

Thebaic version of the Scriptures; but having satisfied himself of the

nature and origin of the enchorial character, he produced the result

to the world anonymously in the Museum Criticum of Cambridge, part

the sixth, published in 1815; being then determined to prosecute the

discovery, but at the same time abstaining from claiming it in a more

substantive form, from the resolution he had previously taken to be

known only as a medical author.

The labour he bestowed on these investigations, and the minuteness and

accuracy with which he copied the papyri, and compared the materials

which came into his hands, would be nearly incredible to those who had

not access to him whilst employed on this pursuit.

In 1816, he printed and circulated two additional Letters relating

to his hieroglyphical discoveries, and the inscription of Rosetta;

the first addressed to the Archduke John of Austria, who had recently

been in this country, the other to M. Akerblad. These letters announce

the progress of the discovery of the relation between the Egyptian

characters and hieroglyphics, forming the basis on which Dr. Young

continued his enquiries, as well as of the system afterwards carried

further in its details by M. Champollion, whose attention had long

been directed to similar studies, and in which he has since so greatly

distinguished himself. The letters were _first published_ when

_re-printed_ in the seventh number of the Museum Criticum in 1821;

and were, with the former letters in that work, beyond all question

or dispute, the earliest announcement of the discovery of a key to a

character which had remained uninterpreted for ages.

In the same year he agreed with Mr. M^{c}Vey Napier to furnish various

articles to the Supplement to the Encyclopædia Britannica, conducted

under the superintendance of that gentleman; and in this work, under

the head “EGYPT,” he first brought out the whole results of his

discoveries in a perfect and concentrated form.

To the Supplement of the Encyclopædia Britannica, Dr. Young furnished

sixty-three articles, scientific, biographical, and literary; the

signature by which they are marked, being two consecutive letters

of the sentence “_Fortunam ex aliis_.” His adoption of such a motto

appears to have been caused by his considering at this period of his

life, that he had not succeeded to his wish or expectation in the

profession which he had chosen, and that he had reason to complain

of some injustice, in that the extent and utility of his labours in

science, after having been fully appreciated by the philosophers of

the Continent, had not appeared to have met with the same acceptance

amongst his own countrymen. But this feeling, as it was transitory, so

it should seem that it was hardly well-founded. By those competent to

form a judgment, he was known to stand at the head both of the letters

and of the science of England; but from the time of his quitting

the professorship of the Royal Institution, all his philosophical

and literary tracts, with the exception of his Lectures and his

communications to the Royal Society, were scattered through so many and

such diverging channels of publication, as well as branched into such

varied lines, that they never were within the reach of any one class of

readers, nor ever in the aggregate came before the public as proceeding

from him; to which may be added, that the slightest reference to his

non-professional works will shew him, in these years, to have used

expressions studiously to conceal himself.

Of Dr. Young’s philosophical articles in the Supplement to the

Encyclopædia Britannica, some of which contain the results of his most

elaborate investigations, the writer of the present memoir is not

competent to speak. Many of his biographical sketches are admirably

given; but he would refer to the Life of PORSON, not only as being

in itself a most masterly production, but as containing a very

interesting indication of some of Dr. Young’s opinions, both on the

value of classical studies, and on the mechanism of the human mind; and

he would instance the dissertation on “LANGUAGES” as containing the

stupendous collections he had made for the subject, when led to it by

reviewing Adelung’s Mithridates for the Quarterly Review.

Early in 1817, Dr. Young having occasion to visit a patient in Paris,

was greatly pleased with his reception in the scientific circles of

that metropolis. With the Baron Alexander Von Humboldt, Messrs. Arage,

Cuvier, Biot, and Guy Lussac, he had made previous acquaintance in this

country. He found himself happy in renewing his intercourse with these

very eminent men, and after his return to London, he went back to Paris

for a few weeks in the summer of the same year.

In 1818, he was appointed by a commission under the Privy Seal,

together with Sir Joseph Banks, Sir George Clerk, Mr. Davies Gilbert,

Dr. Woollaston, and Captain Kater, a commissioner for taking into

consideration the state of the weights and measures employed throughout

Great Britain. Dr. Young acted as secretary at the meetings of this

Board, and to the three Reports which were laid before Parliament he

furnished both the scientific calculations, and the attached account

of the various measures customarily in use. It seems right to state,

that in pursuing these investigations it was his opinion, that however

theoretically desirable it might be, that all weights and measures

should be reducible to a common standard of scientific accuracy, yet

that, practically, the least possible disturbance of that to which

people had long been habituated was the point to be looked to, and on

this ground he was extremely averse to unnecessary changes.

Towards the end of the year 1818, Dr. Young was appointed secretary

to the Board of Longitude, with the charge of the supervision of the

Nautical Almanack, under a new Act of Parliament brought in by Mr.

Croker and Mr. Davies Gilbert; having in the first instance been

nominated in the Act as one of the Commissioners, without his previous

knowledge. This appointment was to him a very desirable one, though the

labour in which it involved him was great, as his anxiety to increase

his medical practice henceforth ceased, and it made that the business

of his life which had always been his inclination.

He now discontinued his residence at Worthing, and devoted the summer

to a hasty tour into Italy, an object which he always had in view. In

about five months he visited all the most remarkable Italian cities,

and amongst other objects of interest, gave the first place to the

examination of the Egyptian monuments preserved in that country. He

returned to England by Switzerland and the Rhine.

From the year 1820 to the end of his life, Dr. Young continued to

furnish a variety of astronomical and nautical collections to Brande’s

Philosophical Journal, the greater part of which were original, and

others which were translated were accompanied by his own comments.

In 1821, he published anonymously an “Elementary Illustration of the

Celestial Mechanics of La Place, with some additions relating to the

motion of Waves and of Sound, and to the cohesion of Fluids.” This

volume, and the article “Tides,” in the Supplement to the Encyclopædia

Britannica, were considered by him to have contained the most fortunate

of the results of his mathematical labours. He proceeds in his own

course and manner of investigation, and uses his own processes, and

the great reach of mind displayed in these works seems universally

acknowledged; but whether he have sufficiently established all the

points which he considered himself to have proved, remains matter of

dispute amongst those best qualified to judge. They were spoken of in

the highest terms of praise by Mr. Davies Gilbert from the Chair of

the Royal Society; but there are some amongst the most distinguished

of surviving English philosophers, who still think that his theory of

the Tides rests too exclusively on analogies, and that many of the

elements of the computation are too much out of human reach to render

the boldness of the original thought susceptible of being subjected to

the severity of mathematical deduction.

Dr. Young as a mathematician was of an elder school, and was possibly

somewhat prejudiced against the system now obtaining, both amongst the

continental and the English philosophers; as he thought the powers of

intellect exercised by a preceding race of mathematicians, were in no

small danger of being lost or weakened by the substitution of processes

in their nature mechanical.

The next year he went again to Paris, and in 1823 he published his

“Account of some recent Discoveries in Hieroglyphical Literature and

Egyptian Antiquities,” in which he gave his own original alphabet, his

translations from papyri, and the extensions which that alphabet had

received from M. Champollion. This was the first non-professional

publication since 1804, to which he had prefixed his name, and made

open claim to his discoveries; having, as stated in his Preface, now

attained his fiftieth year, and having at last determined to throw off

the shackles by which he had hitherto considered himself to be bound by

the etiquette of a medical practitioner.

At this time he attempted to form a society of about fifty subscribers,

for the lithography of a collection of plates of Egyptian antiquities,

subservient to the study of hieroglyphical literature. This work was,

however, entirely carried on by Dr. Young, and was afterwards made over

to the Royal Society of Literature, and continued during the remainder

of his life, to be executed under his supervision.

In 1824, he made an excursion to Spa and to Holland; and on his return

undertook the medical responsibility and mathematical direction of

a society for life insurance. This was established at a moment when

a mania for joint stock companies was springing up in England, and

which at the time was supposed to offer great pecuniary advantages;

but Dr. Young’s most scrupulous regard to what he supposed the

strictest justice, never forsook him: he declined all participation

in the speculation, and confined himself to the performance of the

duties which he undertook. The connexion however with this company

led him into new lines of research, in which he took great interest.

He contributed to the Royal Society a “Formula for expressing the

Decrement of Human Life,” in a letter addressed to Sir Edward Hyde

East, which was published in the Philosophical Transactions for 1826;

and a “Practical Application of the Doctrine of Chances,” to Brande’s

Philosophical Journal for October in the same year; whilst he had a

singular satisfaction in witnessing the prosperity of the concern in

the department under his direction.

The year before this he removed from Welbeck-street to a house which

he had built in Park Square in the Regent’s Park, where he continued

to reside during the remainder of his life, and where, in a situation

to which he was extremely attached, he led the life of a philosopher,

surrounded by every domestic comfort, and enjoying the pleasures of an

extensive and cultivated society, who knew how to appreciate him. He

expressed himself as having now attained all the main objects which he

had looked forward to in life as the subject either of his hopes or his

wishes. This end being, to use his own words, “the pursuit of such fame

as he valued, or of such acquirements as he might think to deserve it.”

In 1827, Dr. Young was elected one of the eight foreign members of the

Royal Institute of France, and was much gratified, not only by the

honour conferred, but by being associated with so many distinguished

persons, with whom he had long been in habits of correspondence and of

friendship.

His health had hitherto, with the exception of the consumptive tendency

which had visited him in youth, been uninterrupted by a day’s serious

illness, and no person would have appeared as giving a promise of

greater longevity; but in 1828 there was a perceptible diminution of

strength. In that summer he went to Geneva, and appeared to suffer what

was to him an unusual degree of fatigue on great bodily exertion, and

his friends from that time could not help remarking symptoms of age

which appeared to be on the increase, and which contrasted strongly

with the singular freedom from complaint which he had hitherto enjoyed.

During the time that Dr. Young was abroad, the general state of the

finances of the country had been submitted to the examination of a

Committee of the House of Commons. Amongst other things, some of

the severer economists had brought under their consideration the

construction and utility of the Board of Longitude as being under the

direction of the Admiralty, and as giving an allowance of a hundred

pounds a year to certain professors of the two universities, whose

attendance was not often called for. The committee did not consist

of members who were much acquainted with science; not one scientific

person was examined before them. The amount of saving by the abolition

of the only salaries which the government of England held forth for the

encouragement of science, little if at all exceeded £500 a year; and

though many projects which might not prove of utility were referred

by Government to this Board, yet the sums actually expended through

them on such as they might conceive to be useful, had been extremely

limited. But on the recommendation of this committee a bill was passed

abolishing the Board, at the same time permitting the Admiralty to

retain the officer entrusted with the calculations of the Nautical

Almanack.

Dr. Young continued to execute these duties; but this singular, and

as it should seem ill-advised proceeding, caused great heart-burnings

and discontent in the scientific bodies, amongst those who considered

themselves or their friends treated unhandsomely as well as

illiberally, in the manner in which their services had been dispensed

with; and the assistance of men of science was soon found to be so

indispensable to many departments connected with the Admiralty, that a

new council of three members, consisting of Dr. Young, Captain Sabine,

and Mr. Farraday, was appointed for the performance of the duties which

had before devolved upon the Board.

The discussions incident to this subject, and the various reports which

Dr. Young had in consequence to draw up, together involved him in more

labour than the situation of his health rendered him competent to

perform without injury, and exacerbated a complaint which it afterwards

appeared must have been long in progress, but which now was bringing

him rapidly to a state of extreme debility.

He had from the month of February 1829, suffered from what he

considered repeated attacks of asthma, and though he said little of

it, as unwilling to alarm those about him, was evidently uneasy at the

situation of his health. This gradually deteriorated. He had in the

beginning of April great difficulty in breathing, with some discharge

of blood habitually from the lungs, and was in a state of great

weakness. His friends and physicians, Doctors Nevinson and Chambers,

considered that there was something extremely wrong in the action of

the heart, as well as that the lungs were very seriously affected.

Though thus under the pressure of severe illness, nothing could be

more striking than the entire calmness and composure of his mind, or

could surpass the kindness of his affections to all around him. He

said that he had completed all the works on which he was engaged, with

the exception of the rudiments of an Egyptian Dictionary, which he had

brought near to its completion, and which he was extremely anxious to

be able to finish. It was then in the hands of the lithographers, and

he not only continued to give directions concerning it, but laboured

at it with a pencil when, confined to his bed, he was unable to hold a

pen. To a friend who expostulated with him on the danger of fatiguing

himself, he replied it was no fatigue, but a great amusement to him;

that it was a work which if he should live it would be a satisfaction

to him to have finished, but that if it were otherwise, which seemed

most probable, as he had never witnessed a complaint which appeared to

make more rapid progress, it would still be a great satisfaction to him

never to have spent an idle day in his life.

His last anxiety concerning the proceedings of one or two persons who

had made him the object of reiterated attacks, in consequences of being

dissatisfied with the arrangements of the Nautical Almanack, was, that

nothing should go forth on his part to increase irritation, and when

papers were sent him which went to enumerate and to prove the errors,

into which these individuals had fallen, his desire was that they

should be suppressed.

In the very last stage of his complaint, in the last lengthened

interview with the writer of the present memoir, his perfect

self-possession was displayed in the most remarkable manner. After some

information concerning his affairs, and some instructions concerning

the hieroglyphical papers in his hands, he said that, perfectly aware

of his situation, he had taken the sacraments of the church on the day

preceding; that whether he should ever partially recover, or whether

he were rapidly taken off, he could patiently and contentedly await

the issue: that he thought he had exerted his faculties through life

as far as they were capable of, but that for the last eight years he

had been careful of straining them to more than he thought they could

compass without injury; that he had settled all his concerns; that if

his health had been continued to him, he might have looked forward to

the prolongation of much that was to be enjoyed; but that though he was

in no other suffering than that of great oppression and weakness, still

that if life were continued in the state he then was of inability to

any of his accustomed employments, he could hardly wish it to be long

protracted.

His illness continued with some slight variations, but he was gradually

sinking into greater and greater weakness till the morning of the 10th

of May, when he expired without a struggle, having hardly completed

his fifty-sixth year. The disease proved to be an ossification of the

aorta, which must have been in progress for many years, and every

appearance indicated an advance of age, not brought on probably by the

natural courses of time, nor even by constitutional formation, but by

unwearied and incessant labour of the mind from the earliest days of

infancy. His remains were deposited in the Vault of his wife’s family,

in the Church of Farnborough in Kent.
