This author states that Wiesner's ferment, which 

 changes cellulose into gum and slime, does not exist. 

 Nickel, of Berlin, has come to the same conclusion inde- 

 pendently. (See Bot. Centralb., 1890, Bd. xi.in, p. 118). 

 The "orciu salzsiiure " reaction of Reichl is a furfurol 

 reaction.

Maintains that the observed results are not due to any 

 pepsin-like body secreted by the plant, but to the action 

 of intruding bacteria, and concludes that the Nepenthes 

 are not carnivorous.

This method consists in using with gelatin or agar, for 

 plate-cultures, etc., a solid opaque substance which is 

 converted into a soluble, transparent substance in the 

 presence of acids. For this purpose Beyerinck adds to 

 the culture- medium a small amount of water in which 

 a very finely divided carbonate of lime has been shaken 

 up. This makes a white opaqne plate. Colonies which 

 secrete acids are soon surrounded by a transparent dif- 

 fusion field. Other carbonates may be used, e. g , zinc 

 carbonate. This method may also be used for the demon- 

 stration of alkali production.
