[Illustration: Profile of M. Lamouroux] Quitting the departed for the living, I send you a profile of M. Lamouroux, the professor of natural history at this university, to whom we have been personally indebted for the kindest attention. His name is well known to you, as that of a man who has, perhaps, deserved more than any other individual at the hands of every student of marine Botany. His treatises upon the _Classification of the Submersed Algæ_, have been honored with admission in the _Mémoires du Muséum d'Histoire Naturelle_, and have procured him the distinction of being elected into the National Institute: his subsequent publication on the _Corallines_, is an admirable manual, in a very difficult branch of natural history; and he is now preparing for the press, a work of still greater labor and more extensive utility, an arrangement of the organized fossils found in the vicinity of Caen. The whole of this neighborhood abounds in remains of the antediluvian world: they are found not only in considerable quantity, but in great perfection. In the course of last year; a fossil crocodile was dug up at Allemagne, a village about a mile distant, imbedded in blue lias. Other specimens of the same genus, comprising, as it appears, two species, both of them distinct from any that are known in a living state, had previously been discovered in a bed of similar hard blue limestone, near Havre and Honfleur, as well as upon the opposite shores of England. But the Caen specimen is the most interesting of any, as the first that has been seen with its scales perfect; and the naturalists here have availed themselves of the opportunity thus afforded them, to determine it by a specific character, and give it the name of _Crocodilus Cadomensis_.
