 wilting begins the stomata often lose water most rapidly, and in consequence 

 close.

 free water surface and from the plant (LIVINGSTON, 1906) is affected very 

 differently by external factors.

44, 11. 10-13, for ASKENASY (1876) . . . they confirm read As a matter of 

 fact, ASKENASY (1876) was able to observe very high temperatures in succu- 

 lent plants. 



1. 23, for oily read succulent 



1. 24, for is of special interest read which URSPRUNG (1903) has confirmed 

 in all essentials, gains in interest 



1. 28, after vital conditions read This opportunity may be taken of noting 

 that F. DARWIN (1904) has invented an apparatus capable of automatically 

 registering the temperature of plant organs, which at the same time permits 

 of inferences being drawn as to the degree to which the stomata have 

 opened.

 read One might imagine that this was the general way in which movements 

 of water took place in the plant, but experiments demonstrate that this view 

 is quite erroneous. 



47, 11. 14-16, for Such experiments as these ... in larger plants read If in 

 experiments of this sort evaporation could be entirely prevented from cells 

 which were not directly in contact with the water, these cells must certainly 

 in the long run become saturated with water by means of osmotic suction. 

 Since, however, this water movement has to overcome very considerable 

 opposition, it goes on too slowly, and on that account suffices only for small, 

 few-celled organisms living in damp situations and transpiring moderately. In 

 larger plants,
