490 THE EXHIBIT 



6. Photographs of racial types — 8. 



Exhibited by: Ilford, Ltd., Ilford, London, England. 



"Experiments in the photography of different racial types by light of 

 various wave-lengths, etc. The most striking result is the distinctly 

 Mongolian type which has become manifest in the photograph 

 of the Negro by infra-red light. The skin pigmentation is also of 

 interest, the photograph on the pan-chromatic plate gaining the 

 appearance of a white man. These experiments are being contin- 

 ued in the hope that an additional process in race study may be 

 evolved." 



7. Photographs showing Asiatic traits in American Indians. 

 Exhibited by: Dr. Pospisil, Museum Moravia, Brno, Czechoslovakia. 



8. Photographs of British Columbia Indian tribes and their blood groups. 

 Exhibited by: Professor R. Ruggles Gates, University of London, 



King's College, Strand, W.C.2, London, England. 



9. Photographs (13) of First Century sculptures showing racial physiog- 



nomy of Near-East nations. 

 Exhibited by: Fahim Kouchakji, 5 East 57th St., New York, N. Y. 



10. Case of skulls and bones, also skiagraph, showing specialized skeletal 



adaptations to such arts as dancing and piano playing. 

 Exhibited by: Dr. Horace Evans, L. I. College of Medicine, 300 

 Henry St., Brooklyn, N. Y. 



11. Case of scapulae, charts, tables and graphs accompanied by 100 



mounted photographs showing heredity and developmental varia- 

 tions in scapular form with interpretation as to their physical sig- 

 nificance. 



Exhibited by: Dr. William W. Graves, Metropolitan Bldg., St. Louis, 

 Missouri. 



"The application of scapular classification to healthy and sick groups 

 representing successive age periods in the life cycle of man revealed 

 the age incidence principle of investigation- — a new and useful prin- 

 ciple in fitness problems. By the aid of this principle the fitness 

 values of the type of discernible inherited variations of structure, 

 future type differentiation, fixation, or maturity, can be deter- 

 mined."
