MacMahon and Jules Grévy. The Pardos de Tavera made a living by receiving the income made by their real properties left in the Philippines. Trinidad enrolled at the University of Paris to continue his degree in medicine. One of his prominent professors was Étienne Stéphane Tarnier (1828–1897), an obstetrician and one of the pioneers of introducing Pasteur and Lister theories in obstetrics. While at the university, he met Louise Ivanovna Krilof and Maria Nikolaevna Lujine, Russian Nihilists. At a visit to one of them, Trinidad learned the idea of the Nihilist movement and shared his own experience of repression while in the Philippines. In 1880, Trinidad received his licentiate in medicine at the Faculté de Médecine de Paris and in 1881, his bachelor in medicine. In mid-1880s, he enrolled in École nationale des langues orientales vivantes (now Institut national des langues et civilisations orientales) and took courses under Pierre Étienne Lazare Favre. In December 1885, he received his diploma in Malay language. During his study at Paris, he tracked down rare collections of books and maps about the Philippines, its culture, tradition and history. He submitted medical articles to various journals, one of them maybe an article he wrote about Pott's disease in 1881 and was published at El Siglo Médico in Madrid. In 1884, he sent an article about faith and folk healing in Luzon to Paris' Journal médecine. In 1886, he published his thesis Contribution a l'etude de la periarthrite du genou (Affections de la bourse sereuse de la patte d'oie) or Contribution to the Study of Periarthritis of the Knee (Diseases of the Bursa of Crow's Feet). While a student at the École nationale, he wrote Contribución para el estudio de los antiguos alfabetos Filipinos (Contribution to the study of ancient Filipino alphabet) in 1884 which was published in Lausanne and El sánscrito en la lengua tagala in 1887. The El sánscrito investigates the etymology and influence of the Sanskrit family of languages to Filipino grammar and orthography. Jose Rizal lamented after the publication of the El sánscrito en la lengua tagala, he said that "I envy Pardo de Tavera's knowledge of Sanskrit." In 1886, he joined several linguistic societies such as Société académique indo-chinoise (Indo-Chinese Academic Society), Société hespagnole d'hygiène (Spanish Society of Hygiene) and Société d'anthrologie (Anthropologic Society). His papers Contribución para el estudio and El sánscrito were later lauded by overseas research journals and
