EXPERIMENTAL DAIRY BACTERIOLOGY 



saccate, liquefaction the shape of 

 an elongated sack, tubular, 

 cylindrical. 



scum, floating islands of bacteria ; 

 an interrupted pellicle or bac- 

 terial membrane. 



sporangia, cells containing endo- 

 spores. 



spreading, growth extending much 

 beyond the line of inoculation, 

 i.e. several millimeters or more. 



stratiform, liquefying to the walls 

 of the tube at the top and then 

 proceeding downwards hori- 

 zontally. 



transient, a few days. 



turbid, cloudy with flocculent par- 

 ticles ; cloudy plus flocculence. 



umbonate, having a button-like, 

 raised center. 



undulate, border wavy, with shal- 

 low sinuses. 



vermiform-contoured, growth like 

 a mass of worms, or intestinal 

 coils. 



verrucose, growth wart-like with 

 wart-like prominences. 



villous, growth beset with hair- 

 like extensions. 



viscid, growth follows the needle 

 when touched and withdrawn ; 

 sediment on shaking rises as a 

 coherent swirl. 



zooglceae, firm gelatinous masses 

 of bacteria, one of the most 

 typical examples of which is the 

 Streptococcus mesenterioides of 

 sugar vats (Leuconostoc mesente- 

 rioides), the bacterial chains 

 being surrounded by an enor- 

 mously thickened firm cover- 

 ing, inside of which there may 

 be one or many groups of the 

 bacteria.
