Author believes he has demonstrated the existence of a 

 nucleus in the bacteria by means of Romanowski's stain- 

 ing method (a mixture of methylene blue and eosin). The 

 plasma stains blue ; the nucleus, which may be small or 

 which may fill nearly the whole bacterial body, stains 

 red or red-brown.
