Bean, The Ear as a Morphologie Factor in Racial Anatomy. Q21 



an organ that is modified, as the funetion changes, may be said 

 to modify itself (Pelletier) we have, in the lower jaw, an 

 example of an organ of this kind. The shape is in response to 

 the activity of nerve and muscle, wandering osteoblasts deter- 

 mine the change in bone deposit. The nervous System does we 

 know affect the medium in which cytodes move directly or in- 

 directly, and may therefore determine the chemiotactic move- 

 ments of the Cytodes. So the beak of Mesoplodon may respond 

 to the desire in Mesoplodon to reach farther forwards in foraging. 

 Cuvier intended to associate the sense organs with foraging. The 

 size of the jaws has much to say to the size of the head. The one 

 statement involves the other. The bone deposit is arranged along 

 definite lines here. 



Dr. Anthony has shown that division of the tendon of 

 the temporal muscle causes the skull in Carnivora (dog) to main- 

 tain its rounded shape and one may be allowed to follow the 

 lead of those who point out that man arboreal in his habits, with 

 climbing feet and hands, changed his habits and adopted a terre- 

 streal life, renouncing his prove position his jaw shortened, his 

 attitude became erect, his head became poised on the top of his 

 vertebral column as his brain case became inflated. 



The Ear as a Morphologie Factor in Racial Anatomy. 



By Robert Bennet Bean (New Orleans). 



Prior to my arrival in the Philippines in 1907 I had made 

 observations of Negro and Caucasian ears in Europe and America, 

 and after my arrival I made extensive studies of Filipino ears. 

 First I studied the ears of the people met on the streets of Manila, 

 including Filipinos, Chinese, East Indians, Spaniards, Englishmen 

 and other Europeans, Mestizos, and Americans both white and 

 colored. Afterwards the inmates of Bilibid prison, where the 

 criminals of the Philippine archipelago are incarcerated, were 

 examined. When the medical survey of Taytay was undertaken I 

 had the opportunity of studying the ears of the East Indians of 

 Kainta, a suburb of Taytay, besides those of the inhabitants of the 

 latter place. In the meantime I had studied the subjeets of Malecon 

 Morgue, where the submerged tenth of Manila and 

 vicinity are reeeived for pauper burial, and I preserved the ears of 

 those bodies that remained unclaimed and were utilized by law for 

 scientific purposes. The foregoing represent random samples of 

 the littoral Filipinos. 



I personally investigated the Moros and Igorots, and further 

 studies were made of the tribes from the interior, principally through 

 the medium of photographs, including the Negritos from many
