2 1 8 SCHIZOM YCETES . 



Micrococcus. — Segments globular, single or separate. 



Bacterium. — Segments globular, adherent to each other. 



Bacillus. \ 



Leptothrix. V Rod-shaped, with vacuoles. 



Beggiota. ) 



Cladothrix. — Rod branched. 



Spirillum. — Rod spiral, like a gimlet. 



Spiroch.^TE. — Rod waved, with active movement. 



Vibrio. — Rod waved, with a slow movement. 



The best literature on this group is, viz : Marshall H. Ward, 

 on the characters or marks employed for classifying the Schizo- 

 mycetes, Annals of Botany^ Vol. VI, London, 1892, pp. 103- 

 144. He gives a brief outline of the history of the classifica- 

 tion of bacteria, presenting in tabular form the various schemes 

 proposed, as, viz : Cohn in 1875, Winter in i83i. Van Teighem 

 in 1884, Flugge in 1886 ; in German, Hueppe in 1886 ; in 

 German, Zoft in 1885 ; De Toni in 1889, Woodhead in 1891, 



For those that can read German I would recommend Hueppe 

 on Bacteria. For the biology, treating on this subject, DeBary 

 is perhaps the best work.
