The latter is the most extraordinary instance of a continuation of 
intense cold that I have ever known. 
My thermometer purchased in London and warranted to sake cor- 
rect, is graduated only to 20 degrees below zero. At sunrise on 
Sunday morning, the 4th inst. the mercury was at 12 degrees under 
zero—and at sunrise on Monday the 5th, the mercury had sunk into 
the bulb: at eight o’clock it had risen to 19. The degree of cold 
therefore was, by that instrument, about the same as that indicated 
by others, viz. 22 or 23 degrees below zero—the most intense cold 
which has been known in New Haven since thermometers have been 
much in use. 
By many observations | have made, I have ascertained that in se- 
vere weather, the mercury at Hartford falls from 5 to 10 degrees 
lower there than at New Haven. 
It was remarked that in the severe winter of 1780, almost all the 
birds of the forest perished. Here and there only, a solitary war- 
bler was heard the next summer.
