AGRICULTURAL BOTANY. 



The transpiration and the ascent of water in trees under Australian con- 

 ditions, A. J. EwART and Bertha Rees {Ann. Bot. [London], 2.'f {1910), No. 

 93. pp. 85-105, (Igms. 5). — In a previous paper (E. S. K., 20. p. 225) one of the 

 authors shows that the ascent of water under the conditions of his experiments 

 is a kinetic prol)leui rather than a static one. He has continued his observa-
