The Rev. P. Kerru on the Origin of Buds. 427 
might have been decided by experiments made by the above or 
by other phytologists many years ago, if the experimenters had 
but instituted them with that particular view. Dr. Hope’s ex- 
periment, for example, might have decided it. If any bud is- 
sued from the wood that was formed within the displaced and 
hollow bark of the Willow on which his experiment was made ; 
then buds are, to say the least, occasionally generated and pro- 
truded into shoots without having been formed originally at the 
centre, and without having come horizontally to the circum- 
ference. So also in the experiments of Du Hamel and of 
Knight, —if any shoot issued from the new layers that were su- 
perinduced by vegetation over a decorticated portion of albur- 
num that had been left exposed to the action of the atmosphere, 
so long as to destroy its vitality, then were buds generated and 
brought to the circumference through a route different from that 
of the horizontal channel. Yet as no fact of this sort has hitherto 
been observed or recorded, as far as my reading or recollection 
goes, and as wounds by decortication or by excision are con- 
tinually happening and again healing up, I began to think of 
looking out for examples, which, if they existed, it could not be 
very difficult to find. | 
On the 20th of September last I observed a shoot actually 
issuing from the lip formed over the section of a lopped branch 
of a Lime-tree. The tree grew in the garden of the Vicar of 
Ashford in Kent. In what did the bud originate? In the lip, 
or in the truncated branch? On the 25th I caused a portion of 
the trunk to be sawed off, so as to expose the origin of the bud 
as much as possible. ‘I'he inspection of it was not decisive, as 
the lip was the growth of one year only, and the bud seemed 
rather to have come from the interior of the wood. 
On the 30th of the same month, I observed in my walks an 
Elm-tree of about eight or nine inches in diameter, and twenty 
feet
