and hair usually darkens. A second set of incisor and carnivorous teeth 
soon mark another stage of progress, and youth succeeds childhood, bring- 
ing an expanded development of bodily form, passions, and intellectual 
power. No individual can reproduce until he reaches the full maturity of the 
type to which he at present belongs, which prevents the race from receding, 
by reproducing a lower type. Leaves grow out or drop off, but never grow 
back. Nature never retrogrades; advance or perish is law to the individual. 
Man can imitate any animal of his species, but no animal can follow man 
beyond its developed powers. Many traits, exemplified in lower animals, are 
successively developed in children, and overcome by proper control; such as 
gluttony, cunning, and deceit—the latter a lingering trait of weakness, gene- 
ral with inferior races. They repeat the antics of a very active and mis- 
chievous race; their first attempts at drawing, resefmble the rude figures made 
by our primeval ancestry and present wild tribes; furthermore, like “children 
of the forest,’ our younger children have not reached the age of self- 
cleanliness. 
The impulsive ferocity of youth, and cooler maturity of age, are but char- 
acteristic types of human transformation in the evolutionary procession. 
Our lives acquire a double significance, when we find we are building an 
inheritance for every one of our descendants, while our race continues. - 
In our growth, we re-evolve, concisely, the story of our race’s lineage, as 
in ‘‘the house that Jack built,” each succeeding verse comprehends all its 
predecessors. Our present bodies now barely float; for, as man acquired his 
upright stature, his frame must have increased in weight and hardened into 
greater rigidity; while the pelvis, to sustain additional weight thus put upon 
it, enlarged, thickened and increased his gravity. 
The head of the human species seems originally to have been large in pro- 
portion to the body, exhibiting a promising germ thus early advanced, a fact 
to which the race may owe its present superiority; and, possibly, this early 
development of the organ capable of acquiring knowledge, may account for 
peculiar sufferings, visited upon woman, more particularly among the most 
intellectually developed. 
The highest type of man has been artificially advanced beyond the condi- 
tion of some portions of the physical world. Miasmatic swamps are yet 
insufficiently reclaimed by time, to permit a white man’s existence where 
they continue. Their present condition would involve his speedy illness and 
dissolution. Lower organizations, congenial to and in harmony with such 
conditions of physical development, may exist and flourish there: but more 
refined types of humanity, require the most perfected physical conditions, for 
their perfect enjoyment and highest attainments. 
Centripetal law has consolidated the Chinese into a positive and exclusive 
people, who delight in ignoring the centrifugal or complimentary force, which 
induces dispersions. They have long clung to unique customs and dress, 
resisting change orimprovement. In their stereotyped form of frozen civiliza- 
tion, differentiation has been arrested, and a peculiar type itensified. Un- 
Alterable fixedness in forms of belief, and habits concreted by centuries, 
furnishes convincing evidence of great antiquity. The black races are 
ethnologically far less developed, and having no fixed belief to displace, are 
more readily converted to any religious sect.
