Farewell, therefore, most illustrious president, whose extraordinary humanity, gentle manners, and uncorrupt integrity, all are unanimous in praising. How agreeable to me was it to be chosen upon this occasion by you, whose friendship, having so often experienced, I am so happy as to experience again. But how can I address you, without at the same time thinking of that prince whom you represent amongst us with so much applause; and this remembrance fills me with emotion. For he is the prince to whom I am indebted for so many favours. It is he who recalled me, out of love to my country, when I was on the point of quitting it at the invitation of a great monarch; recalled me, I say; and, remembering my attachment to physic, founded this professorship, and bestowed it upon me, not without the most honourable tokens of his benevolence; and, by enrolling me in your illustrious assembly, learned professors, he enabled me to address you by the dear appellation of colleagues. Vouchsafe, therefore, favourably to receive him whom he has given you as a companion of your labours, and receive me, most honoured colleagues, in the same disposition of mind with which I come towards you; and shew as much benevolence, facility, and readiness to assist me, as I am ready to shew you veneration, obsequiousness, and docility. Citizens and strangers, illustrious for your great virtues, your extraordinary intellectual endowments, and the high offices you fill, the friendship of many of whom I cultivate with pleasure, receive my thanks for the benevolence with which you have heard me. Finally, I address myself to you, you studious youth, hope of your country and of the church, and ornament of the academy; whatever learning or genius I am possessed of, _Et quicquid in arte mea possum promittere curæ_, _And whatever assistance I can promise by my art_;
