Further work is needed on Ncvroryctes hydrophobice in respect to the mode of division and budding, and with especial reference to the nuclear phenomena; further, in respect to the nature of the permanent forms, encysted or otherwise, which might be expected to exist in animals shortly after recovery from rabies; and finally, work is needed in connection with the sexual phenomena whereby the potential of vitality of the parasite, and with it its capacity for further mischief, is restored. The early illustrations published by Negri, Luzzani, and others of the organism of rabies showed an irregular body with numerous.
