GENERAL SYSTEMATIC BACTERIOLOGY 25 



an organism which he named Actinomyces bovis, the type of a group of 

 organisms now recognized as showing many intermediate characters 

 between the true bacteria and the fungi. Rivolta (1878, p. 169) ob- 

 jected to this name, and proposed in its place Discomyces bovis. 



McNab (1877, p. 340) outhned a classification of the ''Vegetable 

 Kingdom." His lowest group was the Subkingdom Thallophyta, 

 with several classes. The first of these he termed Schizophyta or 

 Protophyta. The orders and families were as follows: 



McNab's Orders of the Schizophyta (1877) 



Order I. Cyanophyceae or Phycochromaceae 



Families. Chroococcaceae, Nostocaceae, Oscillatoriaceae, Rivulari- 

 aceae, Scytonemaceae 

 Order II. Chlorophyllophyceae 



Families. Palmellaceae, Euglenaceae 

 Order III. Schizomycetes 



Family. Bacteriaceae 

 Order IV. Saccharomycetes 



Family. Saccharomyceae 



Van Tieghem (1878, p. 198) introduced the generic name Leuconostoc 

 to designate a streptococcus-like form occurring in large gelatinous 

 masses in syrup, an organism previously described by Cienkowski 

 (1878, p. 12) as Ascococcus mesenter aides. 



Magnin (1878) in his text "Les Bacteries" reviewed at length the 

 classification of bacteria, and adopted the scheme of Cohn. 



Miquel (1879-1881) published a series of articles on the organisms 

 which produce ammoniacal fermentation in urine. He introduced the 

 generic names Urobacillus, Urococcus and Urosarcina for bacilli, cocci 

 and sarcinae which could bring about this change. 



Trevisan (1879, p. 13) created several new genera of bacteria, and 

 evolved the following classification. 



Trevisan's Classification of Bacterial Genera (1879) 



a. Unicellular bacteria, globose or cylindric. Spores solitary within the cells. 

 Multiplication by division of the cells in one, two, or all directions. 



Tribe I. Bacterieae 

 b. Cells free or when quiescent associated in indeterminate mucous 



colonies Subtribe I. Eubacterieae 



c. Cells globose or globose ovoid. Multiplication by vegetative 

 division of the cells in all directions 



Genus 1. Micrococcus
