In the course of those decades, LMJ also published various pamphlets on different themes, not always strictly historiographical. These included juridical topics in both civil and ecclesiastical history, financial and budgetary problems in Portugal and its colonies, the exercise of the functions as councillor on the Lisbon City Council, the results of various public speeches, such as his Oração Inaugural da Abertura do Curso Superior de Letras em 1862 (published in 1863), and finally themes of personal interest, such as specific biographical appreciations, such as that of António Pereira de Figueiredo (published in 1859), or the promotion of cultural questions, exemplified in the discussion of literary property (begun in 1860). He also wrote for various publications, such as Instituto, Semana and Revolução de Setembro.
Despite his leading role in a number of parliamentary interventions, he did not develop his political activity significantly, although he had positive influence in defending the rights of religious associations (a principle that was dear to him, given his New Christian background). In 1863 he joined the Masonic lodge, Liberty, in Coimbra, adopting the name of Fabrício. In the following year, in Lisbon, he joined another lodge with the same name and took part in the initiative that resulted in the creation of the Portuguese Progressive Masonic Confederation. He was a member of the Lisbon Municipal Council, the Associação dos Advogados [Association of Lawyers], the Académie de Législation de Toulouse, the Instituto de Coimbra, the Instituto de África, the Société Havraise d’Études Diverses, the Sociedade dos Amigos das Letras e das Artes da Ilha de S. Miguel, the Sociedade de Agricultura de Ponto Delgada, the Société des Antiquaires de Picardie (Amiens) and was a permanent member of the Academia Real das Ciências.
