Extract of the Meteorological Obfervations make at Stockholm, according to the Thermome-
ters of Celfius and Reaumur. The firft marks nothing at the freezing Point, and 100°
at that of boiling Water ; that is to fay, that 5° of Celfius make 4° of Reaumur.

The greateft variations of the barometer take place in the four firft and four la{t
months of the year: they are between 24° 20’ and 26° 46’: the fcale of the barome-
ter being divided into digits and hundredth parts. It muft however be remarked that
thefe digits are fuch as are ufed by the engineers and geometricians, and of which the
Sweedith foot contains ten; workmen divide the fame foot into twelve digits.
. The
* Note of tranflation. The fcale of Celfius is in ufe in Sweden, partly in Denmark, and in fome other
countries of the north; that of Reaumur in France and many parts of the continent. As in England the
{cale of Fahrenheit is principally in ufe, its correfpondence with that of Celfius is given below.
The freezing point of Celfius is 0°, and that of boiling water 100°; as therefore the freezing point of
Fahrenheit is 32°, and that of boiling water 212°, making a difference of 180°; it follows that the degrees
of Fahrenheit’s fcale will be in addition or fubtra€tion from 32°, as 180° to 100°, oras gto 5 ; upon which
computation the fubjoined {cale is calculated,
