Soon after the publication of his "Specimens," he revisited Germany, and passed some time in Vienna, where he acquired a considerable knowledge of the Austrian court and its manners. He remained long at Bonn, where his friend, W.A. Schlegel, resides. Campbell returned to England in 1820, to undertake the editorship of the _New Monthly Magazine_, and coupled with his name, it has risen to a very extensive circulation. In 1824, Campbell published his "Theodric, a Domestic Tale," the least popular of his works. By his marriage Campbell had two sons. One of them died before attaining his twentieth year; the other, while in the University of Bonn, where he was placed for his education, exhibited symptoms of an erring mind, which, on his return to England soon afterwards, ripened into mental derangement of the milder species. After several years passed in this way, during which the mental disease considerably relaxed, so that young Campbell became wholly inoffensive, and his father received him into his house. The effect of this upon a mind of the most exquisite sensibility like the poet's, may be readily imagined: it was, at times, a source of the keenest suffering. We must now allude to an event in Campbell's life, which will ensure him the gratitude of ages to come: we mean as the originator of the London University. Four years before it was made public, the idea occurred to him, from his habit of visiting the Universities of Germany, and studying their regulations. He communicated it at first to two or three friends, until his ideas upon the subject became matured, when they were made public, and a meeting upon the business convened in London, which Mr. Campbell addressed, and where the establishment of such an institution met the most zealous support. Once in operation, several public men of high talent, headed by Mr. Brougham, lost not a moment in forwarding the great and useful object in view. The undertaking was divided into shares, which were rapidly taken; but Mr. Campbell left the active arrangements to others, and contented himself with attending the committees. With unexampled rapidity the London University has been completed, or nearly so, and Campbell has had the satisfaction of seeing his projected instrument of education almost in full operation in less than three years after he made the scheme public. Although one of the most important,[4] this is not the only public-spirited event of this description, in Mr. Campbell's life; for he was instrumental in the establishment of the Western Literary Institution, in Leicester Square; and at the present time he is, we believe, in conjunction with other eminent literary men, organizing a club to be entitled the Literary Union, whose lists already contain upwards of 300 men of talent, including Sir Walter Scott and all the principal periodical writers of the day.
