Stokes, accompanied by a gold medal struck to com- 
memorate the occasion. 
Quod per annos quinquaginta inter nosmet ipsos Professoris 
munus tam praeclare ornavisti, et tibi, vir venerabilis, et nobis 
ipsis vehementer gratulamur. Iuvat vitam tam longam, tam 
serenam, tot studiorum fructibus maturis felicem, tot tantisque 
honoribus illustrem, tanta morum modestia et benignitate 
insignem, hodie paulisper contemplari. Anno eodem, quo 
Regina nostra Victoria insularum nostrarum solio et sceptro 
potita est, ipse eodem aetatis anno.Newtoni nostri Universitatem 
iluvenis petisti, Newtoni cathedram postea per decem lustra 
ornaturus, Newtoni exemplum et in Senatu Britannico et in 
Societate Regia ante oculos habiturus, Newtoni vestigia in 
scientiarum terminis proferendeis pressurus et ingenii tanti 
imaginem etiam nostro in saeculo praesentem redditurus. Olim 
studiorum mathematicorum e certamine laurea prima reportata, 
postea {ne plura commemoremus) primum aquae et immotae et 
turbatae rationes, quae hydrostatica et hydrodynamica nom- 
inantur, subtilissime examinasti; deinde vel aquae vel aéris 
fluctibus corporum motus paulatim tardatos minutissime per- 
pendisti; lucis denique leges obscuras ingenii tui lumine 
luculenter illustrasti. Idem etiam scientiae mathematicae in puro 
quodam caelo diu vixisti. atque hominum e controversiis procul 
remotus, sapientiae quasi in templo quodam sereno per vitam 
totam securus habitasti. In posterum autem famam diuturnam 
tibl propterea praesertim auguramur, quod, in inventis tuis 
pervulgandis perquam cautus et consideratus, nihil praeproperum, 
nihil immaturum, nihil temporis cursu postea obsolefactum, sed 
omnia matura et perfecta, omnia omnibus numeris absoluta, 
protulisti. Talia propter merita non modo in insulis nostris 
doctrinae sedes septem te doctorem honoris causa nominaverunt, 
sed etiam exterae gentes honoribus eximiis certatim cumu- 
laverunt. Hodie eodem doctoris titulo studiorum tuorum socios 
nonnullos exteris e gentibus ad nos advectos, et ipsorum et tuum 
in honorem, velut exempli causa, libenter ornamus. In per- 
petuum denique observantiae nostrae et reverentiae testimonium, 
in honorem alumni diu a nobis dilecti et ab aliis nomismate 
honorifico non uno donati, ipsi nomisma novum cudendum 
curavimus. In honore nostro novo in te primum conferendo, 
inter vitae ante actae gratulationes, tibi omnia prospera etiam in 
posterum exoptamus. 
The medal was designed by Mr. De Saulles, who 
designed the jubilee medals, and bears the head of the 
recipient in profile on the obverse, and some lines in 
Latin written by the Master of Trinity on the reverse. 
By the courtesy of the University Press, we are able 
to give the accompanying illustrations of the medal. 
The likeness is remarkably good, and the medal, replicas of 
which, in bronze, will be presented to the official delegates, 
was universally admired. We are informed that copies 
in bronze of the medal may be obtained from Messrs. 
Macmillan and Bowes. The number of medals struck 
is limited. 
After the medal had been presented to Sir George by 
the Chancellor, Prof. Cornu advanced and presented 
on behalf of the Institute of France a copy of the 
Arago medal in gold. Immediately after the cere- 
mony, honorary degrees of Doctor of Science were
