The plants were cut down in early summer and once more 

 August 30. The new shoots had reached the height of 30-40 cm 

 on October 15, when they were cut down and dried for analysis. 

 The shoots coming from unhealthy plants already showed 

 distinct signs of the disease.

We see from the above tables that the diseased leaves are con- 

 siderably poorer in nitrogen, fibres and ash. The diseased stems, 

 on the contrary, are apparently rich in nitrogen ; but this does 

 not mean any absolute richness in nitrogen, because the de- 

 velopment of fibres in the diseased stems was very bad, in 

 consequence of which the persentage of nitrogen was much in- 

 creased. If we compare the absolute quantities of nitrogen, 

 then, of course, we should get a remarkable difference. We 

 observe also a great difference between the ash contents of the 

 healthy and diseased plants. These facts indicate that diseased
