Kny (Ber. 16, 1898) found in the case of various roots (Zea Mays, Vicia Faba, 

 Pisum sativum) that absorption (of nitrates and methyl violet) takes place, not 

 only in the root-hair-bearing region, but also for some distance (a few mm.) in front 

 of the latest-formed root-hairs. This fact does not, however, necessitate any modi- 

 fication of the statements already made in the text, regarding the location of the 

 absorbing system in roots. No tissue enters suddenly upon its physiological duties 

 at the moment when its differentiation is completed. On the contrary, its functional 

 activity begins while it is still in process of develojnnent, although it usually becomes 

 intensified as the tissue approaches the mature condition. Kny's results merely 

 provide special illustrations of this general law.
