varied considerably^ The maximum length of those meas- 

 ured was II /i ; 78 per cent, of a large number that were 

 measured varied in length from 3 to 6 /x. 



(2). A culture which was obtained from Koch's lyaboratory 

 (Germany). The bacteria were not quite so actively motile 

 as the hog cholera germs. They stained readily and the fla- 

 gella differed in no appreciable manner from those on the bac- 

 teria from culture (i). There were a large number of short 

 flagella and rings. The number of flagella on the individual 

 germs was estimated in the manner heretofore described. 

 Seventeen of the 200 germs exhibited no flagella, 43 had one, 

 42 had two, 45 had three, 24 had four, 18 had five, 5 had six, 

 3 had seven, and 3 had eight. It is possible that a few bacte- 

 ria had nine filaments each, but there was a doubt as to the 

 exactness of the count. The longest filament measured was 

 13 /A. A large majority of those measured varied from 3 to 7 

 /A in length. 



From the detailed descriptions of the flagella on these three 

 species of bacteria a few comparisons may be made. These 

 can be stated best in tabulated form :

GERMS. 



In comparing the figures in the tables the fact should 

 be kept clearly in mind that thej^ have only a relative 

 significance. The large number of preparations examined 

 and the number of counts and measurements made give them,
