THE BENGUKT IGOROTS. 417 



The masterful work of Eudolph Martin {"Die Inlandstamme der 

 Malayischcn Halbinsel" (^^)) is freelj' utilized in the course of the 

 present study because of the complete presentation in tabular form of the 

 results of recent investigators regarding the people associated with eastern 

 Asia. 



The present article is divided into eight parts the last three of which 

 form a summary ; these parts are as follows : 



I, Statui-e; II, Body Parts; III, Head Form; IV, Plij-siognomy ; V, Descriptive 

 Characters ; VI, Somatologic Race Types ; VII, Three Selected Types ; VIIT, Supple- 

 mentary Theory of Heredity. 



I. STAT PRE. 



The Igorots are a people of small stature (below 160 centimeters) 

 althou.gh many individuals are above the average and some are tall. 

 (Table III.) The average or mean height of 104 aAxxlt males and 10 

 adult females is 154.0 and 146.7 centimeters, respectively. 



Further analysis reveals the fact that these groups are not homogeneous. 

 Only 60 per- cent of the adult males are between the height of 150 and 162 

 centimeters, a wide range for so small a number of individuals. The mode or 

 height of greatest frequency (hence the fashion) is 150 centimeters, although 

 there is only one less individual at 152, 154, and 156 centimeters respectively. 

 The median (which has an equal number of individuals above and below it) is 

 153 centimeters. Tlie minimum is 141 centimeters, and the maximum is 170 

 centimeters. There is an even distribvition of individuals between 148 and 158 

 centimeters; there are 25 above 158 and 11 below 148 centimeters. (Table II.) 

 A curve constructed from the number of individuals at the various heights 

 represented by ordinates and abscissiE would not be a normal Gaussian curve, 

 but would be platykurtic ( flat-topped ( 74 ) ) (45) with a tendency toward tallness, 

 indicating great variability, and more than one type of man. 



The mean height of 14 Bontoe Igorots is 158.6 centimeters. One is only 148 

 centimeters high, one about 150, and 7 are about 164 centimeters. The three 

 groups are significant when considered in connection with similar ones from the 

 highland and lowland regions. 



The mean height of 46 adult male Igorots of the highland region is lo4.9 centi- 

 meters, the minimxmi is 142, and the maximvuu is 170. The height is less than that 

 of the Bontoe Igorots, and the variability is gi-eater, but the height is more than 

 that of the lowland Igorots. 



The mean height of 22 adult males from .the valley is 15.3.0 centimeters. The 

 smallest is from Trinidad in the open country, and the two tallest are from 

 Buguias, which is in the northern end of the province, near Lepanto-Bontoc. 

 The mean height of the 5 men from Buguias is 155.2 centimeters, while that of 

 the 5 from Trinidad is only 152 centimeters. This would suggest that there is 

 an element of small people at Trinidad. The 5 men from Baguio and the 5 from 

 Kabaj'an have a mean height of 156.8 and 151.2 centimeters respectively, which 

 would indicate the same for Kabayan. However, five individuals are not enough 

 from which to determine a mean height, although the measurements do indicate 

 the characteristics of a part of the population. 



The mean height of 22 adult males from Baguio and vicinity is 149.1 centi-
