meters. Their nativity was not ascertained for lack of an interpreter, but many 

 of tliese probably come from Trinidad. For this reason the group is not 

 characteristic for the whole province, but for Trinidad, Baguio and vicinity. 



The individvials of each of the three groups, Lepanto-Bontoc, Highland, 

 and Lowland, may be divided into those of small, those of intermediate, 

 and those of great height. Tlie height of the small individuals varies 

 around 148 centimeters (c/. Negrito) ; that of the large individuals 

 around 165 centimeters (c/. Euroi3ean) ; and tlie lieight- of the greatest 

 number of individuals is about 154 centimeters (cf. Malay). The people 

 of Atoc are slightly above and the people of Baguio and vicinity are 

 slightly below the figures given, but the three groups are defmitely 

 represented there as elsewhere. The conclusion from the examination 

 of the height alone is that at least three groups of people make up the 

 Igorot population. (Table II.) 



The mean height varies directly with the altitude, but probably this 

 variation is not due to the effects of mountain or river, but to the 

 difference in type of the individuals making up the population. The 

 accessible parts have been influenced by infusions of blood from outside 

 of the Province of Benguet, whereas the inhabitants of the inaccessible 

 regions are more like the original type. However, it is possible that 

 outsiders of a bold and daring nature penetrated to the most inaccessible 

 regions, and these may have been tall individuals who increased the 

 average height of the community by their presence and by their progeny. 



The mean height of the Igorots is 3.6 centimeters greater than that 

 given by Martin (26) for the inhabitants of the Malay Peninsula. It is 

 also greater than that of the Veddahs of Ceylon (Sarasin), but it is less 

 than that of the Annamites(l4), the Japanese, the Koreans, the Javanese 

 and various other peoples in the region adjoining eastern Asia. 



Sexual differences in height can not be fairly stated because so few 

 women were measured, but it may be of interest to note them. 



The mean height of the female Igorots is 146.7 centimeters, the minimum 135 

 centimeters and the maximum 154 centimeters. The mode is 146 centimeters 

 and the median 145 centimeters. The female height throughout the world is 

 7 per cent less than the male, or in other words the female is 93 per cent of the 

 male height(27). Therefore, since the mean height of the Igorot women should 

 be only 144.1 centimeters they are proportionately taller than the men. 



STATURE AND RACE. (50) 



Although local conditions acting on the same people for many thou- 

 sand years may effect a change in stature, yet it remains true that stature 

 is a potent factor in race differentiation. Pood and nutrition play a 

 part in determining this characteristic, and artificial selection is at work 

 in modern social life, tall individuals being selected in marriage because 

 goodly stature in youth implies a boimtiful store of vitality. Oceupa-
