rhine and ice; and the infides of garrets and out- 
houfes were covered in the fame manner. 
Jan. 31. — I expofed a glals of proof fpirits, im- 
pregnated with the effence or oil extracted from the 
peel of oranges, at 10 in the evening, in my garden, 
when Flaukfbee’s thermometer flood at 93 0 : At 8 
next morning, I found it no way affedted by the frofl; 
nor did there feem any difference either in tafle, or 
fmell. 
February 6 . — This morning, at 8 o’clock, I ex- 
pofed, in my garden, a drinking-glafs of water, which 
was completely frozen over in one minute’s time; 
and in 1 y minutes the ice was above one-tenth of an 
inch in thicknefs. Farenheit’s thermometer then 
ifood at 21 degrees. 
A coarfe grey thread, two feet in length, being 
dipped in water, froze, in 4, feconds, fo fliff, that I 
took it by one end, and held it upright, as if it had 
been a piece of wire. 
If any part of the human fkin, the finger, for in- 
flance, was wet with fpittle, and immediately preffed 
on a piece of iron, in the open air, it would be froze 
fo faff, as to flick to it ; and, if plucked away haflily, 
would endanger the tearing off the fkin from the flefh. 
I tried the fame experiment upon lead ; but the flick- 
ing was much lefs, and to wood the finger did not 
flick at all. 
In fome places the ice was one- eighth of an inch 
thick, for feveral days together, within-fide of our 
windows (and that even in rooms where fire was kept) ; 
and when the weather grew warmer, it did not fall in 
drops, but vanifhed imperceptibly into the air, by 
which it had been brought thither.
