"In the center of the Place de l'Étoile, from which twelve broad avenues radiate in all directions. Commenced by Napoleon in 1805, but not completed until the reign of Louis Philippe. It is the largest triumphal arch in the world, being 162 feet high and 147 feet wide. The monument is adorned with groups of sculpture representing the military triumphs of the revolutionary and Napoleonic armies."—Webster, 1920

The general rule of downward pressure is "the pressure upon the bottom of a vessel containing a fluid is independent of the shape of the vessel, and is equal to the weight of a prism of the fluid whose base has the same area as the bottom of the vessel, and whose altitude is the distance between the bottom and the upper surface of the fluid, plus the pressure per unit of area upon the upper surface of the fluid multiplied by the area of the bottom of the vessel."

To prove that air has weight and exerts pressure on the earth, this experiment is conducted. A glass tube is filled with mercury. A finger is placed over the end to keep the mercury from slipping out, and the tube is inverted into a cup as shown. The mercury will fall, rise and after a few oscillations, will come to rest at a height above the top of the mercury in a glass equal to about 30 inches.

"For the kingdom of heaven is like unto a man that was a householder, who went out early in the morning to hire laborers into his vineyard. And when he had agreed with the laborers for a shilling a day, he sent them into his vineyard. And he went out about the third hour, and saw others standing in the marketplace idle; and to them he said, Go ye also into the vineyard, and whatsoever is right I will give you. And they went their way. Again he went out about the sixth and the ninth hour, and did likewise. And about the eleventh hour he went out, and found others standing; and he saith unto them, Why stand ye here all the day idle? They say unto him, Because no man hath hired us. He saith unto them, Go ye also into the vineyard. And when even was come, the lord of the vineyard saith unto his steward, Call the laborers, and pay them their hire, beginning from the last unto the first. And when they came that were hired about the eleventh hour, they received every man a shilling. And when the first came, they supposed that they would receive more; and they likewise received every man a shilling. And when they received it, they murmured against the householder, saying, These last have spent but one hour, and thou hast made them equal unto us, who have borne the burden of the day and the scorching heat. But he answered and said to one of them, Friend, I do thee no wrong: didst not thou agree with me for a shilling? Take up that which is thine, and go thy way; it is my will to give unto this last, even as unto thee. Is it not lawful for me to do what I will with mine own? or is thine eye evil, because I am good? So the last shall be first, and the first last." Matthew 20:1-16 ASV
