cases of parturition there is but one of twins; more than the latter 

 is extremely rare. The foetus, a month old, is generally about one 

 inch in height,- when two months, it is two inches and a half; when 

 three, five inches; in the fifth month, it is six. oi' seven inches; in the 

 seventh, it is eleven inches; in the eighth, fourteen, and in the ninth, 

 eighteen inches. Those which are born prior to the seventh month 

 usually die. The first or milk teeth begin to appear in a few months, 

 commencing with the incisors. The number increases in two years 

 to twenty, which, about the seventh year, are successively shed to 

 make room for others. Of the twelve posterior molares which are 

 permanent, there are four which make their appearance at four 

 years and a half, and four at nine; the last four are frequently not 

 cut until the twentieth year. The growth of the foetus is propor- 

 tionably increased as it approaches the time of birth that of the 

 child, on the contrary, is always less and less. It has more than 

 the fourth of its height when born; it attains the half of it at two 

 years and a half, and the three-fourths at nine or ten years; its 

 grov/th is completed about the eighteenth year. Man rarely ex- 

 ceeds the height of six feet, and as rarely remains underfive. Woman 

 is usually some inches shorter. 



Puberty is announced by external symptoms, from the tenth to the 

 twelfth year in girls, and from the twelfth to the sixteenth in boys; 

 it arrives sooner in warm climates, and neither sex, (very rarely at 

 least,) is productive before or after that m.anifestation. 



Scarcely has the body gained the full period of its growth in 

 height, before it begins to increase in bulk; fat accumulates in the 

 cellular tissue, the different vessels become gradually obstructed, the 

 solids become rigid, and, after a life more or less long, more or less 

 agitated, more or less painful, old age arrives with decrepitude, de- 

 cay, and death. Man rarely lives beyond a hundred years, and most 

 of the species, either from disease, accident, or old age, perish long 

 before that term. 



The child needs the assistance of its mother much longer than her 

 milk, from this it obtains an education both moral and physical, and 

 a mutual attachment is created that is fervent and durable. The 

 nearly equal number of the two sexes, the diificulty of supporting 

 more than one wife, Avhen wealth does not supply the want of power, 

 all go to prove that monogamy is the mode of union most natu- 

 ral to our species, and, as wherever this kind of tie exists, thefathcF 

 participates in the education of his offspring, the length of time re- 

 quired for that education allows the birth of others hence the na- 

 tural permanence of the conjugal state. From the long period of 

 infantile weakness springs domestic subordination, and the order of 

 society in general, as the young people which compose the new
