English is the language of the people of England. At the same time it is the language of the people of many other countries, called English-speaking countres.About three hundred million people speak English as their mother tongue and hundreds of millions more speak English as their second languages. Many centuries ago English was spoken in England only.

Then English was brought to other lands in different parts of the world, lands which were British colonies. There were British colonies in America, Asia, Africa, India, Australia and New Zealand. THE FOREIGN LANGUAGES was first brought to the North American continent by English people in 1607. Today the largest English-speaking country by land area is Canada, but by far the most English speakers in North America live in the United States. Many islands in the Caribbean, south of the United States, also speak English.

OXYGEN.

Symbol O. Atomic Weight 15.9.

Priestly, in England, discovered oxygen on the first of August 1774, when he heated oxide of mercury by means of the sun's rays concentrated by a burning glass. It was afterwards discovered independently by Scheele, in Sweden, in 1775.
Properties of Oxygen. Oxygen is at an ordinary temperature a colourless, odourless and tasteless gas, heavier than air and slightly soluble in water. 100 volumes of water at 0° can dissolve 4 volumes of oxygen under the normal pressure of 760 mm. It is converted into a liquid at a low temperature and a high pressure. It boils at — 181^o C.
Occurrence. Of all the elements which occur on our planet oxygen either free or combined is the most widely diffused and is found in the largest quantity. Oxygen occurs in the free state in the atmosphere, of which it forms one fifth by volume. In combination with hydrogen it forms 8/9 of the total weight of water on the earth's surface. It occurs very plentifully in a state of combination in all rocks and is an essential constituent in all animal and vegetable structures.
