Exp. 34. Another experiment on Portugal laurel may be 

 quoted, which confirms the last. 



Lastly the same thing was proved by weighing the amounts 



of water absorbed in given times. 



Exp. 35. Two branches of Portugal laurel which had been 

 doubly sawn on the previous day, and had remained in this con- 

 dition all night, were severed above the double saw-cuts, and were 

 again allowed to absorb water by this new surface.
