Notwithstanding that all these plants belong to different 

 families they have all a more or less high manganese content. 

 Some, such as Maranta arundinacea and Thea sinensis, 

 absorb a fairlv high proportion ; in the first case we obtain 

 ri55 in 100 per cent, of ash, and in the second case 0*898. 



We have investigated the proportions of manganese con- 

 tained in the ash of our restorative crops, and have obtained 

 the following results : — 



The above results and those from the preceding tables 

 clearly show that the manganese in our soils is readily trans- 

 ferred to the vegetation, and although it is impossible to 

 pronounce as to the usefulness of employing salts of man- 

 ganese, we mav take it that their influence would not have 

 a marked effect on the vegetation. 



We have examined the seeds of our leguminous plants 

 to find out whether they contain any manganese, and
