52 PRACTICAL BACTERIOLOGY. 



Examine the animal inoculated with Bacillus capsu- 

 latus aerogenes, and then killed and kept 18 to 24 

 hours. 



Make cover glass preparations from the blood of the 

 various organs. Stain with eosin and methylene blue. 

 Capsules are seen surrounding the bacilli. These may 

 be better demonstrated by staining in the manner de- 

 scribed for staining the capsule of the Pneumococcus.
