the boat carrying the expedition was upset during a severe storm on the 
Cagayan river. As to cast making, although plaster was taken along 
packed in supposedly air tight cans, when these were opened it was 
found to have absorbed so much moisture that it was quite useless; and 
an additional supply purchased in Manila yielded no better results. 
Collection of skeletal material also met with considerable difficulties. 
The people, and hence their burials, are widely separated, and when the 
latter were found the bones, in a large majority of cases, due to the ex- 
cessive moisture, were in such poor condition that they could not be 
collected; twelve graves yielded few parts only of a single skeleton. 
A great obstacle encountered in the examination of the Negrito chil- 
dren was the absence of reHable data as to their ages. Nevertheless, 
the series is an interesting and valuable one and can be confidently ex- 
pected to throw light on a number of important features of the child's 
development among these exceedingly primitive people, who besides 
live in a highly specialized environment. The data are being prepared 
for pubKcation. 
African Negro. — Perhaps the most important large ethnic group for 
anthropological studies, particularly those on the child, is that of the 
pure African Negro, and an expedition of over 14 months' duration was 
carried out under my direction, among several of the more favorably 
situated tribes of this race, by Dr. A. Schiick, of Prague. Principal atten- 
tion was given to the Zulu, from South Natal to North Zululand, and 
the results are measurements of upwards of 1000 children and adolescents 
of this people. These children were reached through the various Mission 
schools and in nearly all cases the age could be exactly determined. The 
results of the measurements and observations, which are already in an 
advanced stage of preparation for pubKcation, are expected to afford a 
solid basis of data concerning the child development of the pure blood 
negro of good stock, which in the future should be of considerable value 
in connection with studies on the development of our own colored 
population. 
Besides the Zulu, the expedition reached a limited number of the 
Bushmen and was engaged on the tribes in British East Africa, including 
some pygmies, when the outbreak of the war in Europe brought the work 
forcibly to an end. 
Besides measurements and observations, the results of this expedition 
consist of numerous photographs; a series of excellent facial casts of the 
Zulu, and an especially valuable series of 20 facial casts of the Bushmen. 
There were also made on this trip numerous collateral observations of 
physiological and medical nature.
