experiments, published some time ago by the Royal Irish Academy, a 
rapidity of ascent of water in the Xylem of the stem of the Cherry

Druck der Gefissluft,” has shown that the air in the vessels of the 
xylem of rapidly transpiring shoots is in a stute of diminished tension, 
and when such a shoot is cut under mercury, the mercury will rise 
in the stem from 20-38 cm ina few seconds. From his experiments 
he concluded that the diminution of the tension of the air in different 
be more rapid than the normal. Experiment, however, shows that 
the- normal amount is more rapid than the abnormal, due to the 
diminished tension of the air in the vessel. @ no error 
has been introduced into the experiments from this cause.—
