TERMINOLOGY OF MICROBMS : VARIATIONS IN DENOMINATION 

 AND CLASSIFICATION. 



IN consequence of the polymorphism of microbes, the 

 terminology employed by different authors is very unstable. 

 We have given the established morphological classification 

 which is still most generally used, but we must here add 

 some remarks which will make it more easy to understand 

 the works recently published on microbes, such as Les 

 Bacteries, by Cornil and Babes, and Micro-organisms and 

 Diseases, by Klein. 



We must first note the tendency to eliminate the names 

 of two genera : Bacterium and Vibrio. 



Cornil and Babes give the name Bacteria, which is the 

 title of their work, to the whole group of Bacteriacece, or 

 microbes strictly so called, regarded as a distinct order. 

 They have consequently been led to suppress the genus 

 Bacterium, in order to avoid confusion ; and most of the 

 species formerly assigned to the genus Bacterium are 

 regarded by them as Bacillus, whether the individual is 

 long or short, mobile or stationary. In the description 

 of the microbes of human diseases, we have conformed
