...more subtle and more cold than that of the middle ; and that of the middle is finer than the lower. The weight of a column of air, reaching from the surface of the earth to the top of the atmosphere, is equal to that of a column of water, of the same diameter, 33 feet high ; for so high, and no higher... | |
