DISTRIBUTION OF HUMAN RACE. 



itself, manifesting a constant tendency to emigration, and being 

 deterred neither by the rigours of the pole, nor the scorching sun 

 of the tropics, it has overspread the globe. According to statistical 

 estimates, which are considered as exact as such calculations can 

 be, it was ascertained that, at the epoch of 1840, the total population 

 of the globe amounted to about 737,000000, which were distri- 

 buted in the following proportions, the number to every square 

 league, taking the length of a league as the 25th part of a degree, 

 being given in the second column : 



The density of the population, indicated in the last column, 

 depends more on civilisation and wealth than on climate. Thus, 

 it is computed that the number of inhabitants per square league in 

 the different states of Europe, are as follows : 



United Kingdom 

 France . 

 Prussia . 

 Russia .

26. Having taken this rapid view of the physical organisation 

 and condition of the human race, let us trace the progress of the 

 animal Man from the cradle to the grave. 



27. In general, man comes into the world singly, or one at a 

 birth. In certain exceptional cases, two are born, and called 

 twins. The cases in which three or more at a birth a*e produced 

 are so extremely rare as not to have received in any language, that 

 we are aware of, a distinct appellation. 



28. It appears by statistical returns, that, upon an average, one 

 case of twins occurs in 90 births ; and that three at a birth has 

 occurred only once in 30000 cases. 



29. Another circumstance, in which the human race is distin- 

 guished from inferior animals, is the independence of the pheno- 

 menon of birth on the season of the year. Animals generally 

 produce their young at that season which is most favourable for 

 their development. Children are born at all seasons. Neverthe- 

 less, in comparing the number of births with the course of the
