402 A Study of the Nasal Bridge in the Anthropoid Apes 
the other end of the simotic scale*, while in the case of the mesodacryal indices 
the Chimpanzee aud Gorilla although widely separated from each other are both 
placed at the low end of the scale next the Negroes, while the Orang-utan 
appears next the Veddahs at the top of the scale. This appears an arrangement 
at least more in keeping with geographical relations, although we make no 
assertion that similarity in nasal form between Veddah and Orang and again 
between Negro and Gorilla or Chimpanzee is due either to closer descent relation- 
ship, or to a common environment compelling species dwelling under it to 
follow similar nasal developments \. As far as the mesodacryal indices are con- 
cerned, English, Egyptian and Hindoo are closer to the Veddah than they are 
to the Negro, and may in nasal form be considered closer to the Orang than to

* There is slender evidence also to place the Orang-utan out of position below the Chimpanzee and 
Negroes in the matter of this index. 
f Dr Hans Friedenthal (Beitrdge zur Naturgeschichte des Menschen, Th. v. " Sonderform der 
menschlichen Leibsbildung," Jena, 1910, S. 61) considers the nasal form determined by environmental 
conditions: "Die anthropoiden Affen als Baumbewohner bedurften keiner Vervolkomniung der 
Atemrohre walirend der Reduktion des Riechorgans, wie die bodenbewohneuden Menschen und 
Paviane. Die Gorilla, mehr dem Bodenleben angepasst als die iibrigen Anthropoiden, ja, mehr als 
viele Ostaffen und Westaft'en, zeigt eine ausgebildetere iiussere Nase als Schimpanse, Orang und 
Hylobates."
