As the shoots were very young, being developed after cutt- 

 ing at the end of May they were especially well fitted for com- 

 parison. The diseased leaves were remarkably poor in nitrogen, 

 fibres, and ash, and among the ash ingredients, there were much 

 less phosphoric acid and potash, and much more lime and 

 magnesia than in the healthy leaves. This result much resem- 

 bles the case of Hosoye (II), the conditions of development being 

 the same in both. In the diseased stems we find also less fibres, 

 but no remarkable difference is to be found in the quantity of 

 nitrogen.
