    ( 3° ) that is the Firft Degree, meafuring from the greateft Cold upward. Which as near as I can find by comparing one Scale with another, i and one Obfervation with another, is nearly as Cold as what the Members of the Academy of Sciences above-mentioned defcribe the Cold of the Northern Circle to be. Their Winter might be Colder than that in which Profeflor Boorhaave fent his Thermometer to Ice-land. The Doctor fays he obferved in Leyden Gar¬ den in 1709, the Spirits to be Four Degrees above the Cold of Ice-land, that is at Fifty De¬ grees without Doors, or Forty-five Degrees within Doors; which is the greateft Cold of Amfterdam as is laid down in my Tables of Heat and Cold. Thus nearly in Cold, does my Calculations and Scale of Cold anfwer to the 4' * ’ above Obfervations. Having by the foregoing Obfervations fhewn how near my Scale for Cold comes to the Truth
