Under ordinary conditions on Earth, elemental hydrogen exists as the diatomic gas, H2. However, hydrogen gas is very rare in the Earth's atmosphere (1 ppm by volume) because of its light weight, which enables it to escape from Earth's gravity more easily than heavier gases. However, hydrogen is the third most abundant element on the Earth's surface, mostly in the form of chemical compounds such as hydrocarbons and water. Hydrogen gas is produced by some bacteria and algae and is a natural component of flatus, as is methane, itself a hydrogen source of increasing importance.
How abundant is hydrogen on the earths surface?
third most abundant

In 1799, English Freemasonry almost came to a halt due to Parliamentary proclamation. In the wake of the French Revolution, the Unlawful Societies Act 1799 banned any meetings of groups that required their members to take an oath or obligation. The Grand Masters of both the Moderns and the Antients Grand Lodges called on Prime Minister William Pitt (who was not a Freemason) and explained to him that Freemasonry was a supporter of the law and lawfully constituted authority and was much involved in charitable work. As a result, Freemasonry was specifically exempted from the terms of the Act, provided that each private lodge's Secretary placed with the local "Clerk of the Peace" a list of the members of his lodge once a year. This continued until 1967 when the obligation of the provision was rescinded by Parliament.
What year did parliament rescind the exemption of 1799 given to the Freemasons?
1967
