4. It is intended to investigate as carefully and as accurately as 

 possible — as it will be done on a larger scale — the changes in the B and D 

 leaves and in leaf-cuttings. I am anything but satisfied with this portion 

 of the work. Also a comparison between the transpiration of the B and D 

 leaves and leaf-cuttings with the average transpiration per unit area of the 

 Pelargonium, will be carried out, for the purpose of seeing how far the 

 small changes in them may be accompanied by increase of transpiration. 



So much claims immediate attention.
