If, how-ever, the two animals are so near to-o-ether in structure and characteristicsas to fall within the limits of what iscalled a species, then, indeed, the off-spring of their union can procreate alongthe new line of life.

It hasbeen maintained by many naturalists,and until recently has been generallybelieved, that these hybrid forms of hu-man life have in them the elements ofperpetuity, that the new variety of man-kind thus established is fecund in itskind, and as well qualified to maintainits independent characteristics as is either of the types from which it hasbeen derived. A closer study of the situation, how-ever, has established the opp
