256 The Rev. PATRICK Kerru’s on 
tremity. Such were the preparations for experiment. What was 
the result? | | 
-On the 25th of July the bean and grain of wheat were swoln 
with moisture that had reached them from above, and were ap- 
parently in a state of incipient germination. 
On the 26th of July, at nine o'clock in the morning, the radicle 
- of the bean, which had burst its integuments, was found to have 
elongated in a straight and horizontal direction to the extent 
of about nearly a quarter of an inch. At mid-day its elonga- 
tion was perceptibly advanced, and the apex was just beginning 
to assume a bend downwards. At nine o'clock in the evening 
it was found to have elongated in a descending direction to the 
extent of nearly half an inch, and was so much bent down- 
wards as to exhibit the figure of a sort of hook or sickle, though 
there was no earth below it, and no moisture coming to it except 
from above. The radicle of tho grain of wheat had not yet burst 
its integuments. | : 
On the 27th of July, at nine o'clock in the morning, the radicle 
of the grain was seen projecting beyond its integuments, and as 
yet ascending at an angle of 45 degrees, or rather forming a sort 
of faint bend, being only one-twelfth of an inch in length. At 
ine o'clock in the evening it measured a quarter of an inch in 
length, and was bent down at the extremity in a perpendicular 
direction, accumbent on the inner surface of the tube; but the 
neath of the plumelet had not yet burst the envelopes of the 
seed... The radicle of the bean measured nearly three quarters of 
an inch in length, having descended in a perpendicular direction, 
and in the open air, below the extremity both of the earth and 
tube. PTER | | 
On the 28th of July the radicle of the bean had not advanced 
much in length, but had augmented considerably in thickness.
