wards the center, grow oval, then round, and, in 
their progrefs to the weftern limb, appear again as 
ovals and lines. My other remarks were, that the 
fpots were twelve days and an half, and about two or 
three hours, in paffing ; that, though fome continued- 
vifible from one limb to the other, a few would 
difappear, after having been vifible feveral days ; and 
others divided into parts 5 that l'carce any fpots ever 
appeared beyond what may be called the polar 
circles of the fun; and that the fame fpot never 
appeared, a fecond time, on the eaftern limb, at lead 
not in the fame form and pofrtion. 
The figures of the fiolar fpots , mentioned in this letter, are Jketches with 
black lead pencil, upon a very fimull ficale. They are accompanied with 
Jhort notes of the fate of the weather at the time of each obfer-vation, and 
fometimes the height of the thermometer is mentioned. Among thefe me- 
teorological remarks, the following ferns the mofi extraordinary. 
February 2 id, 1773, Thermometer at 3 degrees 
below o at Sun-rife. This morning, had there been 
a fnow on the ground, I believe it would have been 
as cold as it was January 2d, 1767, when the ther- 
mometer was 22 degrees below o, there being a 
large fnow on the ground at that time, and none 
now.
