servatives, do not have much effect when putrefaction has 

 once set in. Le Bon's experiments also seem to show that 

 there is no parallelism between the poisonous effects of a 

 putrefying body and that of the volatile products arising 

 from it. They seem inversely proportional. The very 

 small amount of advanced putrefaction products mixed 

 with air breathed by an animal, which is sufficient to kill 

 it, shows the terribly poisonous character of the volatile 

 alkaloids. In conclusion, the author suggested the desirable- 

 ness of a revision of the nomenclature of micro-organisms.
