I am a sincere Catholic as it were Corneille, Racine, La Bruyère, Bossnet, Bourdaloue, Fènelon, as were and still are so many of the most of the honor of out science, philosophy and literature, and have conferred such brilliant ustre on our Academies. I share the deep conviction openly manifested in words, deeds and writings by so many savants of the first rank, by a Ruffini, a Haüy, a Laënnec, an Ampere, a Pelletier, a Freycinet, a Coriolis and I avoid naming any of those living, for fear of paining their podesty. I may at least be allowed to say that I loved to recognize all the noble generosity of the Christian Faith in my illustrious friends the creator of Crystallography (Haüy), the introducers of quinine and stethoscope (Pelletier and Laënnec), the famous voyager on board of the 'Urania', and the immortal founders of the theory of Dynamic Electricity (Frencinet and Ampère).
