In 1826 they publish the first number of the Magazine of Ways of Communication, one of Betancourt’s projects. It includes an article of Resimont on his life and works, as a necrology, with a portrait of him.

In 1828 Alfonso de Betancourt, son of Agustín de Betancourt y Molina, ascends to lieutenant of the First Cavalry Regiment of the Russian Imperial Guard. His sisters, Adelina and Matilde, go to Germany with their mother, with whom they live in Paris from 1840 on.

Rafael Bauzá, the collaborator of Betancourt, dies in Nizhny Novgorod in spring.
