Note 224 — APPENDIX. (continued 2)
Reading edition
Quebec lies nearly in the same latitude as Paris, and from the description which the Emperor Julian has given of the winters he quartered there during his command in Gaul, there seems to be little difference between the winters of France in this respect and the present winters of Canada.—Juliani Imper., Opera.
The author of Récherches Philosophiques sur les Américains supposes the difference in heat between the two continents to be equal to 12 degrees; that a place 30 degrees from the equator in the Old Continent is as warm as one situated 18 degrees from it in America, tom. i., p. 11. Dr. Mitchell, after observations carried on during thirty years, contends that the difference is equal to 14 or 15 degrees of latitude, p. 257.—Heriot's Travels through the Canadas, p. 117.
