riment was made iipan the bulbous roots of tulips, and 
with the fame fuccefs. 
II. A young Scotch fir, which bad two compleat 
fltoots and a third growing, and which confequently ^vas 
in its third year, was put into the cold mixture which 
w'as between 15° and 17°. The laft flioot froze with 
great difficulty, which appeared to be owing in fome 
meafure to the repulfioii between the plant and the wa- 
ter. When thawed, the young ffioot was found flaccid. 
It was planted ; the firft and fecond flioot we found re- 
tained life, while the third, or growing flioot, withered. 
III. A young flioot of growing oats with three leaves, 
had one of the leaves put into the cold mixture at 22°, 
and it fooii was frozen. The roots w'ere next put in, but 
did not freeze ; and when put into the ground, the whole 
grew, excepting the leaf which had been frozen. The 
fame experiment was made upon the leaves and roots of 
g bean, and attended with the fame fuccefs. 
A leaf taken from a growing bean was put into 
the cold mixture, and frozen, and afterwards thawed, 
which ferved as a ftandard. Another frefli leaf was 
taken and bent in the middle upon itfelfj a fmall flial- 
low leaden veffel was put upon the top of the cold mix- 
ture, and the two leaves put upon its bottom; but one- 
half of each leaf was not allowed to touch the veflel by 
the bend; the cold mixture was between 17° and 15% 
and the atmofphere at 22°. The furfaces of the two 
leaves wffiicli were in contadl with the lead were fooiv' 
frozen
