education was mainly conducted by himself, a probability which is certainly not discounted by the wide and promiscuous character of his reading. From the outset of his introduction to letters he is known to have been an omnivorous reader of all books that came in his way, nor was his mode of studying classical authors that by which the scholastic proficiency essential to aspirants for success at college examinations is usually attained. O’Brien did not resemble the ordinary boy-student, to whom Roman or Greek classics represent merely a given quantity of “text” possessing certain peculiarities of diction or allusion which have to be nicely dissected, analysed, and mastered, but who regards the subject-matter of each work as being of very minor importance. On the contrary, he manifestly read them as authors, or rather authorities upon the subjects with which they respectively dealt, paying, so far as we can perceive, little or no attention to the diction or distinctive literary character of their writings. The result was what might be expected. If, whilst an undergraduate of Dublin University, it be true that he was regarded by many of his fellow-students as a prodigy of learning, their seniors appear to have been less enthusiastic about his scholarship, for we have not been able to discover his name in the college archives.[4] Still, from the fact of his having obtained, after he took his degree in 1831, the appointment of private tutor to the sons of the then Master of the Rolls,[5] it is possible that he may have distinguished himself previously.
