I changed the barks of the branches of a peach 
and a nedtarine tree ; that, which was placed on the 
peach-tree, healed perfectly, and the branch pro- 
duced a quantity of bloom laft feafon ; but the bloom 
of the whole tree, as well as of feveral others again ft 
the fame wall, was intirely blafted. The gardener 
cut off the branch of the nedtarine, when he was 
pruning, and nailing the trees, as he did of feveral 
others, on which I had made experiments of the fame 
kind ; againft which he declared his opinion ftrongly, 
at the time of making ; and faid, he was fure the 
branches would all die, and the wall be quite bare in 
thefe parts ; which, I fuppofe, he imagined would be 
a reflection on his fkill in pruning and nailing a tree. 
About the beginning of November laft, I cut off 
one of the arms of the perdrigon plumb-tree, which 
had the experiment made on it in 17 58, to examine 
what effedt it had on the wood ; to which, I found 
the bark between the circumcifions more firmly 
united, than in any other part. There was a dark 
vein, which ran through the wood in that part, 
which appeared of a harder texture than the reft of 
the branch. 
On examining the minutes I had taken from time 
to time, of the obfervations I had made on thefe ex- 
periments, which J imagined I had been very exadt 
in, I find I had omitted noting down any relative 
to the effedt they had on the growth of the circum- 
cifed branches. I did not compare them by meafure 
with other branches ; but as far as I can fpeak by recol- 
ledtion, it has retarded the growth. I can be almoft 
pofitive, that the cherry-tree, mentioned in the fe- 
cond experiment, the trunk of which had been cir- 
cumcifed ■
