Potato and Friedlaender's Bacillus.* — G. Dauinezon concludes 

 from his observations that a vegetable substratum may in certain cases 

 play an important part in the dissemination of pathogenic bacteria in 

 nature, and particularly in water. From the tubers of the potato the 

 pneumo-bacillus of Friedlaender was isolated. The organism was also 

 found in well-waters.
