Inoculation of the Soil with Alinit. *— L. Malpeaux made pot and 

 field experiments with oats, maize, and white mustard. The results indi- 

 cated that alinit, which may be considered as a bacterial manure, only 

 acts in soil rich in organic matter by rendering available the insoluble 

 nitrogenous substances present. Consistent results were obtained in 

 the pot experiments ; but on a larger scale the results were conflicting, 

 and the conclusion is drawn that alinit has no favourable effect on 

 ordinary arable soil.
