DEAR SIR, 
Northampton, 
May 3, 1776. 
A CCORDING to my promife, I now proceed to 
give you a fhort account of fome obfervations and 
experiments concerning the late fevere froft. As fome 
of the phenomena appeared to me not a little furprizing, 
I minuted them down at the time they occurred. 
Jan. 27th, The great quantity of fnow which had 
continued falling almoft every day for three weeks, had, 
for thefe five or fix days paft, rendered the roads im- 
pafiable; and the poll, both upwards and downwards, 
was flopped, the fnow being drifted from fix to ten feet 
deep or upwards. This morning the froft became 
fuddenly very fevere; the wind full Eafl, accompanied 
with fnow. The barometer flood at 29^. A thermo- 
meter, according to Fahrenheit’s fcale, which hung in 
my parlour, where there was a good fire, flood at 33% 
that is, only i° above the freezing point. After it had 
been fufpended a quarter of an hour on the Cliinefe jjali- 
fades before the flreet-door facing the South, it funk to 
20 0 , that is, 12 0 below the freezing point. At five 
o’clock the fame evening, it fell to 16 0 . At this time 
eggs in the market cracked in the womens bafkets, and 
appeared in a coagulated Hate, of the confiflence of bees- 
wax. This evening was placed on my garden-wall, facing 
the Eafl, half an ounce of each of the following liquors in 
a cup; viz. lemon-juice, vinegar, and red port-wine. 
Jan. 28th, This morning, at eight o’clock, the "barome- 
ter flood at 30. The thermometer at 12 0 , that is, 20° 
below
