BIMANA. 39 



trils, two lachrymals (unguis) in the internal angles of the orbits and the 

 single bone of the lower jaw. Each jaw has sixteen teeth; four cutting 

 incisors in the middle, two pointed canines at the corners, and ten tuber - 

 cula-ted molares, live on each side. At the extremity of the spine of his 

 scapula, is a tuberosity called the acromion, to which the clavicle is at- 

 tached, and over its articulation is a point called the coracoid process, with 

 which certain muscles are connected. The radius revolves upon the ulna, 

 owing to the mode of its articulation with the humerus. The carpus has 

 eight bones, four in each range ; the tarsus has seven ; those of the re- 

 maining parts of the hand and foot may be easily counted by the number 

 of lingers and toes. 



Enjoying uniform and regular supplies of nourishment, the fruit of his 

 industry, Man is at all times inclined to the " plaisirs d'amour," without 

 ever experiencing that irresistible and violent impetus which marks the 

 passion in quadrupeds. His organ of generation is not upheld by a bony 

 axis; the prepuce does not tie it down to the abdomen, and it hangs 

 loosely in front of the pubis. Numerous and large veins which effect a 

 rapid transfer of the blood of his testes to the general circulation, appear 

 to contribute to the moderation of his desires. 



The uterus of woman is a simple oval cavity; her mamms, only two in 

 number, are placed upon her breast, and correspond with the facility she 

 possesses of supporting her child upon her arm. 



Physical and Moral Developement of Man. 



The term of gestation in the human species is nine months ; and but 

 one child is usually produced at a birth, as in five hundred cases of partu- 

 rition there is but one of twins ; more than the latter is extremely rare. 

 The fcetus, 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 or 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 proportionably 

 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 growth is completed about the 

 eighteenth year. Man rarely exceeds the height of six feet, and as rarely 

 remains under five. 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 ar- 

 rives sooner in warm climates ; and neither sex (very rarely at least) is 

 productive before or after that manifestation. 



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.
