A member of various scientific academies and of the Accademia dei Lincei (1875), towards the end of his life he directed, together with Enrico Betti, the journal Il Nuovo Cimento (from 1893 to 1900), which he owned and bequeathed to the newly founded Italian Physical Society.

[3] Felici's law was formulated in the years when Franz Ernst Neumann, Wilhelm Eduard Weber, Hermann von Helmholtz, Emil Lenz and others were studying the phenomenon of induction.

[2] He died in S. Alessio di Lucca on June the 11th 1902 and was commemorated on December the 2nd at the Accademia dei Lincei by his student and later university lecturer Antonio Roiti.

[5] In the Notizie sull'Istituto di Fisica sperimentale dello Studio Pisano (News on the Institute of Experimental Physics of the Pisan Study) of 1914, Augusto Occhialini reports on the aforementioned commemoration of Angelo Battelli, a beautiful biography of him is sketched, with a drawing of Felici's famous switch, and the episode, as epic as it is curious, relating to the search with physical methods for the bullet that remained, after the wound suffered at Aspromonte, in Giuseppe Garibaldi's malleolus, which was brought to Pisa in 1862 to try to extract it.

Using two copper rods mounted on a block of bone terminating in two very thin silver plates, connected to a battery and a galvanometer, Felici was able to work out whether or not the probe touched the bullet, identifying it.
