These facts may amaze us: and we might add others alike astonishing in regard to the air we breathe which appears so light and harmless. This air during the most violent storms moves not less than 100 miles per hour and as you all know is most destructive in its ravages. And as to its weight it is a certain fact that every man of an ordinary size sustains a pressure of not less than 30,000 pounds, and the weight of the whole atmosphere amounts to five thousand 357 trillions 147 thousand millions of tons.
