partake of the activity of the reft, but were ablb- 
lutely in the fame ftate, which all trees are in 
during winter. A rofe tree, in the fame polition, 
fhewed long fhoots with leaves and buds ; it had 
even fhot a vigorous branch upon its ftalk, whilft 
a branch which palled through, to the outlide, 
had not begun to produce any thing, but was in 
the fame ftate with other rofe-trees left in the 
ground. This branch is four lines in diameter, 
and eighteen inches high. 
The rofe-tree on the outfide was in the fame 
ftate; but one of its branches drawn through to 
the inlide of the hot-houfe, was covered with 
leaves and rofe-buds. It was not without afto- 
nilhment that I faw this branch Ihoot as brilkly 
as the rofe-tree which was in the. hot-houfe, 
whofe roots and ftalk, expofed as they were to 
the warm air, ought, it fhould feem, to have 
made it get forwarder than a branch belonging 
to a tree, whofe roots, trunk, and all its other 
branches were at the very time froft-nipt. Not- 
withftanding this, the branch did not feem af- 
fected by the ftate of its trunk ; but the action of 
the heat upon it produced the fame effeCt as if 
the whole tree had been in the hot-houfe. 
It would be ufelefs to give an account of the 
diary I kept throughout the courfe of this in- 
terefting experiment. It may be fufficient to ob- 
ferve, that the walk of nature was uniformly the 
fame. The interior branches continued their pro- 
ductions in a regular manner, and the external 
ones began theirs at the fame time, and in the 
fame manner, as they would have done, had they 
been left in the ground. The fruits of the in-
