196 GENERAL SYSTEMATIC BACTERIOLOGY 



In the translation of the Vorlesungen by Coppen Jones (1897, p. 32) 

 this is spelled Bacillaceae. In the second edition (1903, p. 60) the diag- 

 nosis given is: 



Vegetationskorper cylindrisch, ellipsoidisch, eiformig, gerade; bei den kurzen, 

 fast kugeligen Formen und die Trennung von Kokken schwer; Teilung immer 

 senkrecht zur Langsachse, als Wuchsform nur unverzweighte Ketten. 



In the original description four subfamilies are listed. Bacilli, 

 Bacterinei, Bactrillei and Bactridei. Later (1903) the three subfamilies 

 recognized were Bacilleae (with four genera) Clostridieae (two genera) 

 and Plectridieae (two genera). 



Schmidt and Weis (1902, p. 91) likewise used this family designation, 

 including the three genera Bacterium, Bacillus and Pseudomonas with. 

 the following description : 



Die Zellen sind cylindrisch, ktirzer oder langer stabchenformig, gerade. Die 

 Zellteilungen geschehen nur nach einer Richtung des Raumes. Vor der Teilung 

 strecken sich die Zellen m einer senkrechten Richtung zu der spater gebildeten 

 Scheidewand. Endosporbildung bei mehreren Arten bekannt. 



The name has also been used as a group designation by Fliigge (1908). 



This family name is also used by Benecke (1912, p. 188) to include 

 the rod-shaped bacteria without sulphur or bacteriopurpurin, un- 

 branched and not forming a pseudoplasmodium. 



Winslow et al. (Committee Soc. Am. Bact., 1917, p. 561) used this as 

 a designation for their seventh family of the Euhacter tales. The diag- 

 nosis is: "Rods producing endospores, usually Gram-positive. Flagella 

 when present peritrichic. Actively decompose protein media through 

 the agency of enzymes." 



Winslow et al. (Committee Am. Soc. Bact., 1920, p. 212) in their final 

 report used the same diagnosis. 



Castellani and Chalmers (1920, p. 601) state: 



Cette famille peut etre d^finie : Eubacteriales avec cellules longeres ou courtes, 

 flagell^es ou non flagell6es; sporogenes ou non sporogSnes, mais toujours cylin- 

 driques et droites et se divisant seulement dans une direction. 



Le genre type est Bacillus Cohn 1872, mais ce genre et I'autre genre ancien, 

 Bacterium, renferment un si grand nombre d'especes et de vari6t4s que nous avons 

 essay6 de simplifier leur diagnose en d^finissant les tribus et les genres suivant. 



They divide the family into 10 tribes. 



Bergey et al. (1923, p. 272) included this as the fifth familj^ of the order 

 Eubacteriales with the description : "Rods producing endospores, usually
