AFRICA.

TABLE I. Population and extent of some of the coun

TABLE II. Population of some of the cities of Africa,

Note. The above statements of the population of several of the countries and cities of Africa, are founded mostly on the doubtful estimates of travellers." A great part of Africa is entirely unknown, and the total amount of its popu lation is very uncertain. Some estimate it as high as 150 millions; and some reduce it to 30 millions.

THE EARTH.

TABLE I. Extent and population of the globe, with the

population to a square mile.

Note. The amount of the population of the globe is uncertain; some estimate it upwards of 1,000,000,000, and some reduce it to less than half that number.

TABLE II. Religion. The numbers attached to the dif ferent religions.

Note. Christians are distributed into three general divi. sions, Roman Catholics, Protestants, and the Greek Church. They are estimated in the following proportion.

TABLE III. Language

TABLE IV. Human Life.

It is computed that the number of deaths throughout the globe, in proportion to the number of inhabitants, is as 1 to 33; or that the number of deaths in 33 years is equal to the whole number of inhabitants. If we compute the population of the earth at 700 millions, and the number of births in proportion to the number of inhabitants as I to 291, and deaths as 1 to 33, we shall have the following results nearly:

TABLE V. Temperature.

The second column exhibits the mean temperature at the level of the sea in the successive latitudes; the third shows the height of perpetual congelation, or the elevation at which water freezes throughout the year.

Note. Mountains which rise above the point of perpetual con gelation, are covered with snow throughout the year.

Note. By comparing the statements on this table it will be seen that places on the eastern continent are warmer, that is, have a higher temperature, than places in similar latitudes in America.
