"The Negrito and Allied Types in the Philippines and The Ilongot or Ibilao of Luzon" by David P. Barrows is an early 20th-century study examining the Negrito people and their relationships with other groups, notably the Ilongot, in the Philippines. Through years of physical measurements and observations, Barrows investigates the physical and cultural traits of these groups, such as the Negrito's unique physical attributes and the Ilongot's headhunting practices. In doing so, the book aims to showcase the significant role of Negrito heritage in shaping various Philippine populations, exploring the complex connections between ethnicity, ancestry, and social organizations within the islands, serving as an analysis of these specific ethnic societies.
