Edward Stanley Robertson, Dictionary of National Biography… (1893)
“ In 1855 he graduated B.A. as senior moderator in classics and in philosophy. In the same year the board of Trinity College endowed non-foundation scholarships for the relief of those labouring under religious disabilities. Maguire competed, and was elected. In 1861 he obtained the law studentship at Lincoln's Inn, and in 1862 was called to the English bar. Although highly commended by Lord Westbury, he soon ceased to practise, and, returning to Dublin about 1866, set up as a private teacher in Trinity College. ”
