174 RACTEHIA AND THE GVM OF LINSEED MUCILAtiK. 



Glucose-gelatine stnh. — This was filiform; at the surface, a 

 restricted crateriform area bore a Mliite lihn. The liquefied area 

 became funicular. 



Xutrient agar-stroke. — At first, narroNv, white and glistening, 

 the stroke became broad, fat-like, canary-coloured, raised and 

 terraced. 



Saccharose-potato-agar sfroke. — A broad, raised, translucent 

 white slime was formed. It became mottled, parti}- transparent, 

 partly translucent. Finally, the culture gravitated to the foot 

 of the vertical slope. 



Potato. — There grew scant}-, dry, white crusts, which fused and 

 became pale buff, while the medium darkened. 



liouillou. — This remained clear, but produced a fiocculent sedi- 

 ment anil slight surface ring. The indol reaction was obtained, 

 and nitrates were not reduced to nitrites. 



Milk. — This became slowly peptonised and developed an acid 

 reaction.
