a circular

 made another incifion round the bark, and then a perpendicular one 



ones, and feparated the cylinder of bark

 nicely from the wood, co\ 



from the air for about a quarter of an hour, when the wound be<yan

 it round rather tightly with bafs, fo as to cover the wound entirely, 

 and half an inch above and below the circumcifions. 



In about a month the bark began to fwell above and below the

Mr. Fitzgerald afterwards took a cylinder of the bark from the

 other tree. The bark of one had a leaf-bud and two apples growing
