Dr. Graves received his degree of Bachelor of Medicine at the University of Dublin in 1818. After this he studied for some time in London, and then spent three years on the continent, at Berlin, Göttingen, Vienna and Copenhagen, as well as in Paris and certain Italian schools, finally studying also for some months in Edinburgh before his return to Dublin. As Dr. Stokes very well says: "In this large and truly liberal education, which embraced the training of the school, the university and the world, we can discover in part the foundations of his subsequent eminence. He did not content himself, as is so commonly the case, with commending--to use his own words--'the life of a practitioner without practice,' but he made himself intimate with the recent discoveries and modes of thinking in every great school of medicine, whether abroad or at home, and formed friendships with the leading physiologists and physicians of Europe, with many of whom he kept up a correspondence during his life." An interesting incident in his travels serves to illustrate very well his facility for the acquisition of languages. Once while on a pedestrian journey in Austria he neglected to carry his passport, and was arrested as a spy. He was thrown into prison and for a time his condition seemed serious enough. He insisted that he was a British subject, but his assertions in this matter were immediately repudiated by the Austrian authorities in the little town, who insisted that no {170} Englishman could possibly speak German as well as he did. He was kept in prison for some ten days until authentic information could be obtained with regard to him, and, during this time, such was the state of the prison that he suffered many privations. Later in life this gave him a sympathy with the prisoners of Ireland and led to his making suggestions for the amelioration of their condition.
