The 20th of January, a week after this difpo- 
frtion, all the branches that were in the hot-houfe 
began to difclofe their buds. In the beginning 
of February, there appeared leaves, and towards 
the end of it, fhoots of a coniiderable length, 
which prefented the young flowers. A dwarf 
apple-tree and feveral rofe-trees, being fubmitted 
to the fame experiment, fhewed the fame appear- 
ance then as they commonly put on in May ; in 
fhort, all the branches which were within the hot- 
houfe, and confequently kept in the warm air, 
were green at the end of February, and had their 
fhoots in great forwardnefs. Very different were 
thofe parts of the fame tree, which were without 
and expofed to the cold. None of thefe gave the 
leaft flgn of vegetation ; and the froft, which was 
intenfe at that time, broke a rofe pot placed on the 
outflde, and killed fome of the branches of that very 
tree, which, on the infide, was every day putting 
forth more and more fhoots, leaves, and buds, fo 
that it was in full vegetation on one fide, whilft 
frozen on the other. 
The continuance of the froft occafioned no 
change in any of the internal branches. They 
all continued in a very brilk and verdant ftate, as 
if they did not belong to the tree, which, on the 
outfide, appeared in the ftate of the greateft fuffer- 
ing. On the 15th of March, notwithftanding 
the feverity of the feafon, all was in full bloom. 
The apple-tree had its root, its ftem and part of 
its branches, in the hot-houfe. Thefe branches were 
covered with leaves and flowers ; hue the branches 
of the fame tree, which were carried to the outfide, 
and expofed to the cold air, did not in the leaft
