middle of [[underline]]April[[/underline]], and the polar ice being thus brought and fixed 30 [[circled page number]]60[[/circle]] degrees nearer to us than the place where it was generated, will naturally so far counteract the influence of our vernal Sun that we shall not enjoy warm weather till [[underline]]June[[/underline]], nor then if a north east wind blows long together. --- In autumn, when our weather would otherwise be Cold, the frozen Zone between 60 and 70 Degrees having been at length dissolv'd, the frigid influence is suspended, and our winter is proportionally warmer as our summer had been colder. 
But in some winters the ice at the pole is never dissolved, for when it happens that the atmosphere is there filled with gross humid particles, that freeze into a thick rhime, or hoary frost, a mist is generated which the solar rays cannot pierce with sufficient force to operate by reflexion from the surrounding promontories of ice; when this happens, it is likely to continue several seasons, and the Zone of ice that used to lie between 60 and 70, is then farther removed, and lies between 80 and 90, and our seasons being then free from foreign influence, will be hot and cold in proportion to our latitude at the solstices, and the weather will be in an intermediate state at the equinox. Upon these humble offered hypotheses the regularity or irregularity of our seasons depend, and the dryness or humidity, or the clearness or obscurity of the polar Atmosphere. Gents. Mag. Feb. 9 1755. p. 73.
In cold and frosty weather the pores of the surface of the earth are so shut up and closed that the vapours cannot rise as they do in warm weather. Dr. [[underline]]Woodward's[[/underline]] Hist. of the earth.
Places which lie in the same degree of latitude have not the same degree of Heat and Cold, and of this [[underline]]Norway[[/underline]] affords a more remarkable instance than any other country. On the east side, the cold is so severe, that cataracts formed of the largest rivers are arrested in their course and frozen into huge fragments of ice as they fall. The spittle is no sooner out of the mouth than it is frozen into ball, and rebounding from the ground rolls along like hail, and the effect of cold on the balls of horse-dung, newly dropt, is yet more amazing, for they move and leap upon the ground, the motion being caused, by the conflict between the sharp dense air which penetrates them from without and the warm air which is expelled from within. But the western parts, which lie in the same parallel of latitude, have temperate winters, the frost seldom continuing more than a fortnight, all the bays and lakes being open, and the air moist and cloudy. To account for this difference of season, it is remarked, that
