    vibrios with Leptothrix. This opinion, which was not favorably received by the authors who adopted nearly all of the generic groups of Ehren- berg and Dujardin, is to-day accepted by many botanists, above all since the labors of Cohn. (See below: classification.) At all events, it is to M. Davaine (1859) that we are indebted for clearly pointing out that the vibrioniens are vegetables, nearly allied to the algae, and especially to the confervas. This same author, having observed some mo- tionless bacteria, thought it necessary to give this character great consideration, and to estab- lish a fourth group, the genus Bacteridium, which he added to the three others admitted by Dujar- din ; but in this creation he was less happy than in his placing the vibrioniens among the vege- tables ; for we shall see further on that this char- acter of mobility or of immobility is not absolute, and that it depends upon the age of the bacterium or upon certain conditions relating to the medium in which it is placed. The most recent complete exposition of the classification and of the ideas of M. Davaine is found in the Dictionnaire Encyclop. des Sci- ences Medicales, art. Bact^ries (1868). It may be summed up as follows: — Filaments straight ] Moving sponta-) Rigid. . Bacterium. or bent, but not [ neously . . j Flexible. Vibrio. in a spiral . ) Motionless Bacteridium. Filaments spiral Spirillum.
