 is an abstract of a paper read before the Botanical Section of the German Association 

 of Naturalists and Physicians, in which an account is given of sonic investigations 

 relative to alinit. The substance seems to be pure cultures of Bacillus ellenbachcusis. 

 Further investigations are said to be necessary to establish its value in practical 

 agriculture.

 authors claim that mustard must be included in the enumeration of those plants 

 capable of assimilating the free nitrogen of the air.
