physics ; and Professor Cremona of Rome, whose work on the Theory 
of Projection has met with great celebrity, and has been translated 
into many European languages. The Society had also the pleasure 
of hearing an address on Cosmic Dust from the Ahhe Renard, who 
is not a Eellow of the Royal Society, hut is known to ns by his 
contributions to the records of the “ Challenger ” Expedition. 
I have now only to express the hope that the Eellows may meet 
at the commencement of next Session, recruited for fresh exertions. 
In connection with the Tercentenary celebration, I ought to 
mention that the Council did me the honour to appoint me as their 
delegate to represent the Society on that occasion. To my great 
regret, I was unable from the state of my health to attend the 
celebration, and our Secretary, Professor Tait, was appointed in my 
place. In the course of the discharge of the duty thus devolved on 
him, he presented a Latin Address from the Royal Society to the 
University, the terms of which were furnished by our Librarian 
Mr Gordon, and are as follows: —

tercentenariam Universitatis Jacobi Sexti, Scotorum Regis, con- 
celebrare et ornare vult. Etenim Societas Regia est filia Universitatis 
vestrse, cui suavissimo commercio et sanctissima necessitudine devincta 
est. Quam multi philosophi, Universitatis S^natores, pars magna 
sunt et fuerunt rerum a Societate gestarum. 
Hoc die solemni memoriam magnorum virorum Academicorum 
renovare juvat, et tanquam Jacobi Sexti antecessor, Macbethus, 
obstupuit proleptica visione seriei regum Scotiae futurorum, sic 
sed retrospectu contemplamur hodie illos sceptriferos scientise 
principes, Senatores Universitatis, qui ah urnis suis adhuc intellect 
turn humanum regunt. En Gregorius, inventor telescopii reflexione 
agentis; — Maclaurtnus qui sublimiores res cosmicas illustravit, 
tiuxum refluxumque maris, solis vias, lunseque labores ; — Robisonus 
et Eorbesius, ambo Secretarii Societatis Regiae, alter expositor 
encyclopsedicus totius corporis philosophiae naturalis, alter nova 
theoria de molibus conglaciatis clarissimus ; — Monroi, anatomic!
