BIMANA, OR MAN.

Introduction, we will add, that he has thirty-two vertebrae, of which seven belong to the neck, 
twelve to the back, five to the loins, five to the sacrum, and three to the coccyx. Of his ribs, 
seven pairs are united to the sternum by elongated cartilages, and are called true ribs ; the 
five following pairs are denominated false ones. His adult cranium consists of eight bones ; 
an occipital {occipito-hasilaire ) ; two temporal ; two parietal ; a frontal ; an ethmoidal, and a 
sphenoidal. The hones of his face are fourteen in number namely, two maxillaries ; two 
jugals, each of which joins the temporal to the maxillary bone of its own side by a sort of 
handle named the zygomatic arch ; two nasal bones ; two palatines, behind the palate ; a vomer, 
between the nostrils ; two turbinated bones of the nose in the nostrils ; two lachrymals in the 
inner 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 molars with 
tuberculated crowns, five on each side, in all thirty-two teeth. His blade-bone has at the 
extremity of its spine or projecting ridge a tuberosity, named the acromion, to which the 
clavicle or collar-bone is connected, and over its articulation is a point termed the coracoid 
process, to which certain muscles are attached. The radius turns completely on the cubitus 
or ulna, owing to the mode of its articulation with the humerus. The wrist has eight bones, 
four in each range j the tarsus has seven ; those of the remaining parts of the hand and foot 
may be easily counted by the number of digits. 
Enjoying, by means of his industry, uniform supplies of nourishment, Man is at all times 
inclined to sexual intercourse, without being ever furiously incited. His generative organ is 
not supported by a bony axis ; the prepuce does not retain it attached to the abdomen ; but 
it hangs 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 mammae, only two in number, are situated 
on the breast, and correspond with the facility she possesses of supporting her child upon her 
arm. 
PHYSICAL AND MORAL DEVELOPEMENT OF MAN. 
The ordinary produce of the human species is but one child at a birth j for in five hundred 
cases of parturition, there is only one of twins, and more than that number is extremely rare. 
! The period of gestation is nine months. A foetus of one month is ordinarily an inch in 
I height; at two months, it is two inches and a quarter; at three months, five inches ; at five 
months, six or seven inches ; at seven months, eleven inches ; and at nine months, eighteen 
inches. Those which are born prior to the seventh month usually die. The first or milk 
I teeth begin to appear a few months after birth, commencing with the incisors. The number 
increases in two years to twenty, which are shed successively from about the seventh year, 
! to be replaced by others. Of the twelve posterior molars, which are permanent, there are 
I four which make their appearance at four years and a half, four at nine years ; the last four 
being frequently not cut until the twentieth year. 
The foetus grows more rapidly in proportion as it approaches the time of birth. The infant, 
on the contrary, increases always more and more slowly. It has upwards of a fourth of its 
height when born, attains the half of it at two years and a half, and the three fourths at nine or 
ten years. By the eighteenth year the growth almost entirely ceases. Man rarely exceeds 
six feet, and seldom remains under five. Woman is ordinarily some inches shorter. 
Puberty manifests itself by external signs, from the tenth to the twelfth year in girls, and 
from the twelfth to the sixteenth in boys. It arrives sooner in warm climates. Either sex 
very rarely produces before the epoch of this manifestation. 
Scarcely has the body attained its full growth in height, before it commences to 
increase in bulk ; fat accumulates in the cellular tissue. The different vessels become
