marinorum in classe non ignotus, lampade trans oceanum e 
Gallia sibi tradita feliciter accepta, etiam exteris gentibus 
subito affulsit, velocitatem immensam eleganter dimensus, qua 
lucis fluctus videntur (ut Lucretii verbis utar)

Scandinavia ad nos misit scientiae mathematicae professorem 
illustrem, qui studiorum suorum velut e campo puro laudem 
plurimam victor reportavit. Idem Regis sui auspiciis, qui 
praemiis propositis magnum huic scientiae attulit adiumentum, 
etiam exterarum gentium ad communem fructum prope vigint?

the degree which the University had been anxious to 
confer upon him. 
The following are the speeches delivered by the Public 
Orator in presenting to his Grace the Chancellor the 
several recipients of the honorary degree. 
(1) PRor. Cornu (PARIS). 
Primum vobis praesento artium plurimarum Scholae Paris- 
iensis professorem, quem in hoc ipso loco die hesterno per- 
spicuitate solita disserentem audivistis, virum non modo solis 
de lumine in partes suas solvendo, sed etiam orbis terrarum de 
mole metienda per annos plurimos praeclare meritum. Lucis 
in natura explicanda, quanta cum doctrinae elegantia, quanta 
cum experimentorum subtilitate, quam diu versatus est.’ Idem 
quam accurate velocitatem illam est dimensus, qua per aeris 
intervallum immensum lucis simulacra minutissima transvolitant, 
“* Suppeditatur enim confestim lumine lumen, 
et quasi protelo stimulatur fulgere fulgur.” 
Lucis transmittendae in Acuradnpopia quam feliciter lampada a 
suis sibi traditam ipse etiam trans aequor Atlanticum alii 
tradidit. 
(2) Pror. DarBoux (Paris). 
Sequitur deinceps vir insignis Nemausi natus, Parisiensium 
in Universitate illustri geometriam diu professus et scientiarum 
facultati toti praepositus.  Peritis mota sunt quattuor illa 
volumina, in quibus superficierum rationem universam inclusit ; 
etiam pluribus notum est, quantum patriae legatus deliberation- 
ibus illis profuerit, quae a Societate nostra Regia primum in- 
stitutae, id potissimum spectant, ut omnibus e gentibus quic- 
quid a scientiarum cultoribus conquiritur, indicis unius in thes- 
aurum, gentium omnium ad fructum, in posterum conferatur. 
Incepto tanto talium virorum auxilio ad exitum perducto, inter 
omnes gentes ei qui rerum naturae praesertim scientiam exco- 
lunt, sine dubio vinculis artioribus inter sese coniungentur. 
(3) Pror. MicHELSON (CHICAGO), 
Trans aequor Atlanticum ad nos advectus est vir insignis, qui 
ea quae professor noster Lucasianus de aetheris immensi regione, 
in qua lux propagatur, orbis terrarum motu perturbata, olim 
praesagiebat, ipse experimentis exquisitis adhibitis penitus ex- 
ploravit. Lucis explorandae in provincia is certe scientiarum

(5) PRoF. QUINCKE (HEIDELBERG). 
Universitatem Heidelbergensem abhinc annos quadraginta pro- 
fessorum par nobile spectroscopo invento in perpetuum illus- 
travit. Adest inde discipulorum plurimorum in scientia physica 
praeceptor, qui et in instrumentis novis inveniendis sollertiam 
singularem et in eisdem adhibendis industriam indefessam prae- 
stitit. Ei qui in scientiae physicae ratione universa versati, 
viri huiusce inventis utuntur, etiam de sua scientia verum esse 
confitebuntur, quod de arte oratoria praesertim dixit Quinti- 
lianus :—‘‘in omnibus fere minus valent praecepta quam ex- 
perimenta.”’ 
(6) Pror. VorcT (GOTTINGEN). 
Universitatem Goettingensem, a Rege nostro Hanoveriensi 
Georgio secundo conditam, vinculo non uno cum Universitate 
nostra coniunctam esse constat. Constat eandem etiam per 
annos prope quinquaginta Caroli Frederici Gaussii, scientiae 
mathematicae et physicae professoris celeberrimi, gloria esse 
illustratam, qui curh ingenio fecundissimo disserendi genus con- 
summatum coniunxit. Iuvat inde professorem ad nos advectum 
excipere, qui scientiae eiusdem pulcherrimam nactus provinciam, 
etiam lucem ipsam et crystalla ingenii sui lumine illustravit. 
After the congregation, a garden party was held in the 
beautiful old gardens of Pembroke College, where a 
numerous and brilliant company assembled and listened 
to the music of the Royal Artillery Band. 
In the evening, a dinner, at which were present some 
220 of the guests of the University and their hosts, took 
place in Trinity College Hall. His Grace the Duke of 
Devonshire presided, and after the health of the Queen had 
been drunk he proposed, in a felicitous speech, the health 
of the hero of the day. The toast was drunk with the 
greatest enthusiasm. The only other toasts were 
“The Guests,” proposed by Prof. George Darwin, and 
responded to by Lord Lister ; and “ The Chancellor,” pro- 
posed by the Vice-Chancellor. In responding, the 
Chancellor thanked the Master and Fellows and Trinity
