THE HUMAN SPECIES. 245 



a nucleus, or centre of existence, exclusively adapted for their 

 permanent abode, whereas the contrary is clearly shown, by the 

 presence of unadulterated races, and mixed tribes of the other 

 two stocks, in both conditions suited to the same geographical 

 region. This circumstance likewise indicates the probability 

 of a great atmospheric change in relation to man, after a dilu- 

 vian cataclysis, if it be admitted that this equatorial vicinity 

 was once the real Nigritia of the woolly-haired type. Now, 

 as it is evident the centre of development belonging to this 

 type is at present in the tropical regions of Africa, and, as was 

 before shown, that there are indications of a third being in 

 preparation, under the same latitudes in South America, while 

 the Oriental is gradually disappearing, it might be asked, 

 whether there is not here the indication of a submerged conti- 

 nent, and another instance of that progressive migratory move- 

 ment from the east to the west, or expansion and decay, 

 ordained to be the fate of the great human typical stocks, and 

 impelled by laws whose operation may be perceived without 

 affording the means of tracing their causes beyond probable 

 assumptions ? Yet this physical procession over the earth by 

 longitudes may not be without ultimate connection with that 

 intellectual march of Man by latitudes, which, while departing 

 from the temperate regions of our northern hemisphere, and 

 arriving at the extremity of the habitable south, appears to 

 repeat, on a greater, the workings of civilization which it com- 

 menced on a less scale in Europe, and thus to be evolving the 

 mysterious problem of human fusion into one great family, led 

 by one religious system, and trained to the sciences and litera- 

 ture of Europe. 



As the Malays are nowhere expansively homogeneous, and in 

 most places only tenants of coasts or parts of islands, varied 

 marks of national adulteration are constantly perceptible. In 

 general, however, their distinctive characters are marked by a 

 comparatively small head, measuring, in the capacity of the 

 skull, according to Dr. Morton, from sixty-four to eighty-nine
