About tbe age of eighteen he repaired to the Omverfity of 
Frankfort, where he fpent three years in a diligent appli¬ 
cation to mathematics and philofophy. From Frankfort 
he proceeded to W rati (law, or Breflaw, in Silefia, where 
he ftudied for the (pace of one year. He returned to Frank¬ 
fort, and remained there three years more, paying the mod 
sntenfe application to the ftudy of phyfic. A contagious 
Siftemper having broken out at that place, the ftudents 
were difperfed, and Liddel retired to the univerfity of 
Roftock. In 1590 he returned once more to Frankfort. 
But, having there heard of the increafing reputation of 
the Academia Julia, eftabliffied at Helmftadt by Henry 
duke of ferunfwick, Mr. Liddel removed thither; and 
foon after his arrival was appointed to the iirft or lower 
profefTorfhip of mathematics. From thence he was pro¬ 
moted to the fecond and more dignified mathematical 
chair, which he occupied for nine years, with much cre¬ 
dit to himfelf and to the academy. In 1596 lie obtained 
the degree of M.D. was admitted a member of that fa¬ 
culty, and began publicly to teach phyfic. By his teach¬ 
ing and his writings he was the chief fupport of the me¬ 
dical fchool at Helmftadt; was employed as iirft phyfician 
at the court of Brunfwick, and had much practice among 
the principal inhabitants of that country. Having been 
feveral times elected dean of the faculties both of pliiio- 
fopliy and phyfic, he had in the year 1604. the honour of 
being cliofen protestor of the univerfity. But neither 
academical honours, nor the profits of an extenfive prac¬ 
tice abroad, could make Dr. Liddel forget his native 
country. In the year 1600 lie took a final leave of the 
Academia Julia; and, after travelling for fome time 
through Germany and Italy, he at length fettled in Scot¬ 
land. He died in the year 1613, in the 52d year of his 
age. By his la ft will he bellowed certain lands purchafed 
by him near Aberdeen upon the univerfity there, for the 
education and fupport of fix poor fcholars. Among a 
variety of regulations and injunftions for the manage¬ 
ment of this charity, he appoints the magiftrates of Aber¬ 
deen his truftees, and folemnly denounces the curfe of 
God on any perfon who (hall abufe or mifapply it. Hi9 
works are, 1. Dilputationes Medicinales, Helmftadt, 1603, 
4to. 2. Ars Medica fuccinfle et perfpicue explicata, 
Hamburghi, 1607, 8vo. 3. De Febribus Libri tres, Ham- 
burghi, 1610, i2tno. 4. TraGatus de Dente aureo, Ham¬ 
burghi, 1628, i2ino. This performance Dr. Liddel pub- 
lifiied in order to refute a ridiculous (lory then current, 
of a poor boy in Silefia, who. at feven years of age, hav¬ 
ing loft fome of his teeth, brought forth, to the aftonifh- 
snent of his parents, a new tooth of pure gold. Jacobus 
Horftius, doclor and profeffor of medicine in the Acade¬ 
mia Julia at the fame time with our author, had publilh- 
ed a book, which he dedicated to the emperor Rudol- 
phus II. to prove that this wonderful tooth was a prodigy 
lent from heaven to encourage the Germans then at war 
with the Turks; and foretelling, from this golden tooth, 
the future victories of the Chriftians, with tbe final de- 
flruflion of the Turkifli empire and Mahometan faith, 
and a return of the golden age in 1700, preparatory to 
the end of the world. The impofture was foon after dIB- 
covered to be a thin plate of gold, fkilfully drawn over 
the natural tootli by an artiftof that country, with a view 
to excite tbe public admiration and charity. 5. Artis

LFDEN (John-Henry), alcarned and benevolentSwede, 
who died at Nordkoping on the 28th of April, 1798. He 
prefented to the univerfity of |Jpfal, or rather to the ftu¬ 
dents of Enft Gothland, who frequented it, nearly the 
whole of his library, confiding of about 6000 volumes, 
on condition of its being made public ; he likewife en¬ 
dowed the univerfity with the intereft of a capital of 
23,33 rix-dollars, (330I.) for the acquifition of new works. 
L I D 
Ills ftep-mother, Ifedwig-Sophia Liden, a-woman replete 
with refpe£lability, and who feemed to rival him in a6ts 
of beneficence, funk a capital of 2777 rix-dollars, the in¬ 
tereft; of which was to ferve as a falary to a librarian. 
' He and his ftep-mother left a falary for an amanuenfis, to 
be employed in the library of the univerfity of Upfal; and 
the intereft: of a capital to form a purfe of rix-dollars, 
every year, for two ftudents not opulent, that fliould dif- 
cover talents. Liden likewife gave the fum of 1000 rix- 
dollars to the Royal Academy of Stockholm, add a like 
fum to the Academy of Belles Lettres, Hiftory, and An¬ 
tiquities, of the fame city, of which he was a member. 
He alfo gave 500 rix-dollars to the library of the Aca¬ 
demy of Abo, to purchafe new books; and a like fum, 
with the profit of two works which he had printed at his 
own expenfe, to the library of Linkoping. He added a 
number of his own valuable books to the library of the 
Swedifli Academy; as alfo to the library of the univerfity 
of Lund, to that of Abo, and to the library of the Gvm- 
nafium of his own city. In 1791, on the death of his 
ftep-mother, he gave 200 rix-dollars to the cheft of the 
poor of the city of Linkoping. Tbe king confirmed thefe 
different difpofitions of Liden, and irifured their dura¬ 
tion. It would be difficult to enumerate all the benefi¬ 
cent gifts which he distributed in his life-time ; which, 
however, did not amount to lefs than 11,622 rix-dollars; 
and he never let flip any opportunity of doing good. Li¬ 
den languifhed under a complaint of the joints for twen¬ 
ty-one years, feventeen of which he paft’ed without being 
able to quit his bed. As his pain and tlfe obligation, of 
remaining always bed-ridden, gave him no little uneafi- 
nefs, to calm his mind in the moments of ill-humour, he 
placed before his eyes, on his bed, the two words, pati¬ 
ence and meekness : and thefe he praflifed to the end 
of his life. As he never could be ufeful to his country 
in the employ which had been entrufted to him, that of 
adjunct in the chair of hiftory in the univerfity of Lund, 
lie demanded to refign it, which lie obtained in the moft 
honourable manner, October 29, 1776, retaining the title 
of profeiTor. His bed was every day furrounded by the 
moll interefting perfons of both fexes, who found the 
greateft pleafure in his converfation, and which made him 
forget, for a time, the ftate of fuffering in which he was. 
The prefent (exiled) king, while hereditary prince, the 
duke of Sudermannland, the duke of Oftrogothland, 
and many diftinguifhed lords of the court of Sweden, 
went to vifit him ; and, in general, no traveller of dif- 
tinftion quitted Nordkoping without calling upon him, 
and without admiring his imperturbable patience and 
good-humour. When not engaged with vilitors, he wa? 
employed in literary labours; he read, he dictated and 
publifhed many works during his malady, but their ti¬ 
tles have not reached us. In the firft years of his fufter- 
ings he kept up a very extenfive correfpondence with a 
number of learned foreigners. His folid erudition, joined 
to great refinement of underftanding, rendered his fociety 
extremely agreeable; and his probity, his love for hi* 
country, his qualities, and his virtues, fecured him the 
general efteem of alibis fellow-citizens; this efteem exiit-s 
to this day. He was a model of beneficence. His me¬ 
mory is ftill dear to a great number of diftinguifhed learned 
men of Sweden, whom he fupported in their youth, and 
was their counfellor in their ftudies. He lived in a very 
cecononaical manner, in order to have the pleafure of do¬ 
ing good to others.
