56 66 England in spring; the heat of Africa, in summer; the temperature of Italy, in June; the sky "of Egypt, in autumn; the cold and snows of Norway and the frost of Holland in winter; "the tempests of the West Indies, in some shape, "the whole year round; and the winds and "variable weather of Great Britain, every month "of the year." The character of the climate of that country, according to the same authority, is to be uniformly variable, and to have nothing fixed. In 1787, the greatest degree of cold was 5o, the greatest heat 96° 1; that is to say, a difference of 91° 1 between one extreme and the other, or 36° more than in Buenos Ayres. It is affirmed that the thermometer rarely rises to 86°, in Santiago de Chile, and that only at mid-day, when there is a cessation of the land and sea-breezes, that blow alternately, which never lasts in that state longer than three hours. We will conclude by observing, that the variations of temperature are not great in Buenos Ayres, although they are very frequent. It is true that a transition from 86° to 60°. is not experienced within twenty-four hours in summer, nor from 37° to 41. below zero in winter, as is the case in Philadelphia; and that here a dif ference of 91° between the highest and the lowest temperature is not known, as it is there; nevertheless, variations of six, ten, and even of twenty degrees, are of frequent occurrence, and expose the inhabitants to diseases resulting from irregular and suppressed perspiration, and from a considerable evaporation, which takes place from the skin, without the individual being aware of it. Greatest Lowest ele-Greatest Lowest Mean tem elevation on vation, 6th degree of degree of perature of zero. 204 STATE OF THE WEATHER. Days of Thunder Clear Days. Foggy Days Rainy Days. and Lightning.
