barriers between them, come to Brazil. He cannot deny the 
deterioration consequent upon the amalgamation of races, more 
wide spread here than in any country in the world, and which is 
rapidly effacing the best qualities of the white man, the negro, 
and the Indian, leaving a mongrel, nondescript type, deficient in 
physical and mental energy.” 
Schultz in speaking of race mixture in Peru says, ‘‘The degen- 
eration there is even greater and has been more rapid than in 
the other South American countries and the cause is the infusion 
of Chinese blood into the veins of the white-negro-Indian com- 
pound. There are scarcely any Indo-Europeans of pure blood in 
Peru, for with the exception of pure Indians in the interior the 
population consists of mestizos, Zambos, mulattoes, terceroons, 
quadroons, cholos, musties, fusties and dusties; crosses between 
Spaniards and Indians, Spaniards and negroes, Spaniards and 
yellows; crosses between these people and the cholos, musties 
and dusties; crosses between mongrels of one kind and mongrels 
of other kinds. All kinds of cross breeds infest the land. The 
result is incredible rottenness.”’ In all the great South American 
melting pot and also in Mexico and Central America we meet 
with much the same situation. 
Schultz’s book (Race or Mongrel?) is a plea for racial purity. 
The downfall of nations which has been explained in so many 
different ways is accounted for in this volume as a result of hy- 
bridization. Greeks, Romans, Hindoos, Egyptians and Lom- 
bards have all been destroyed by the admixture of foreign blood. 
“‘Nature suffers no mongrel to live.’ Only the pure races thrive 
and attain a high degree of development. 
Lapouge speaking of race crosses tells us that ‘En general, 
les résultats de ces unions n’ont rien d’avantageux. Laideur, 
vulgarité, manque de vigueur, moindre durée de vie, tares phys- 
iques nombreuses, nos sang-mélés ont tout contre eux.” Mr. 
Madison Grant in a recent work (The Passing of the Great Race) 
which has attracted considerable attention, represents the racial 
hybrid as no higher than the lower race from which he sprang. 
“The cross between a white man and an Indian is an Indian;
