inforced with crosses of pure blood ? The Liplappens 
(Dutch-Javan mestizos) are said in the third generation to 
yield only females, and these sterile ; but the pure Dutch 
race is also said to become speedily sterile in Java. 8. Do 
the products of the first cross resemble most the male or the 
female parent ? and is there any difference between those of 
the direct and of the inverse cross ? 9. How many return 
crosses restore apparent purity of blood ? and what character¬ 
istic marks of the cross remain longest (hair, eyes, nails, &c.) ? 
10. What is the intellectual and moral position of mixed 
breeds between races, one of which is greatly superior to the 
other? (Social conditions may interfere with this problem ; 
a despised and helot race can hardly maintain a high moral 
standard.) 11. Does a mixed breed develop any new and 
special aptitudes or talents ? or is it superior in any respect 
to both its constituent stocks ? 12. Can any direct cause be 
alleged for sterility where prevalent, eg., physical unsuit¬ 
ability, frequency of prostitution or of abortion, &c. ? 13. 
Does the external form seem to be taken from one parent, 
and the constitutional habits from the other ? 14. Do 
individual members of one family of mongrel blood differ 
greatly from one another by approximation to one or other 
parent ? J. B.

Observations on natives who have had little communication 
with Europeans would be of course the most valuable, though 
those made on any natives would be of much interest. General 
remarks on expression are of comparatively little value ; and 
memory is so deceptive that it ought not to be trusted. A 
definite description of the countenance under any emotion or 
frame of mind, with a statement of the circumstances under 
which it occurred, would possess much value. For such in¬ 
vestigations a “snap shot” camera will be found of great 
assistance when it can be used. 
1. Is astonishment expressed by the eyes and mouth being 
opened wide, and by the eyebrows being raised ? Are the
