Living Head from Denniker's Data. 



Cephalic Index from Xasiil Index: i,,= 86")70 - -11335 /,., 

 Nasal Index from Cephalic Index: i.v= 149-216- -93980 7^. 



Now these results arc extremely interestiug. We see that platyrrhine characters are inter- 

 racially associated with dolichoce[)hally and vke versd in quite a marked degree. We have 

 in each case a quite sensible negative correlation. 



The first thing then we arc tempted to ask is : whether this is true intraracially ! We kuow 

 already that it is true for the Naqada crania*. The following give the results for two Bengal 

 races for the living head. 



Murmi Tribe, Chittagong Hills. 

 J/c,=V9-914, J/.v, = "4-889, 

 o-„ = 3-32r>0, o-.v,= 6-0248, 

 re.v= - -2284, 



OraoH Tribe of Chota Nagpur. 

 ,V„=75-481, .l/v, = 86-2öO, 

 o-c, = 3-3632, <r,v, = 7-7830, 

 rev= - -2392. 



The reconstruction cquations from these races are : 



Murmi Tribe: ic= 89-353- -12604/,., 



4=112-983- -41383 ic, 



Oraon Tribe: ic= 84-396 - -10336 i.v, 



4=128-030 -•55352/,;. 



Now these intraracial results are of the same kind as the interracial results, and, considering 

 the smallne.s.s of the data dealt with, not widely diftbrent in numerical magiiitude. We niay, 

 we think, conchide accordingly that the association of platyrrhine and dolicliocoi)halic characters 

 is intraracial as well as interracial and the degree of this association has mach the same 

 quantitative magnitude in both casest. It seems legitimate in this instance to draw general 

 conclusions from intraracial to inten-acial results as far as the living hejid is concenied. 



(4) lUuMration III. On the Interracial Relationships of the Orbital to the Cephalic 

 and Nasal Indices of the Cranium in Man ( o )- 



Denniker givcs for a few races from data of very divei-se worth the nioan orbital, cejjhalic aud 

 nasal indices. The results obtained by Dr Alice Lee are as foUows : 



Orbital and Cephalic Index. 



(21 cases) 



J/„ = 85-786, J/„=75-36T, 



o-o, = 2-9172, o-„ = 4-0895, 



/•,^='4486 + -n7(!. 



Cephalic and Nasal Index. 



(16 cases) 



J/,., = 74-000, J/.v,=52-231, 



a-c, = 3-4595, <r.v, = 4-1210, 



r„.= - -4460 + -1354. 



Sasal and Orbital Index. 



(30 cases) 



i/.v, = 50-287, i^<„ = 87-023, 



<r.v, = 4-4205, <r„, = 9-8969, 



r^=- -10881 -1217. 



*■ Biometrika, Vol. i. p. iöö, The reconstruction formulae iu this casc arc: 



i'c = 78-054- -09914 7.V, 



i.v=67-206- -2-2094 /e, 



equations wkich uaturally differ totally from tbose for the living head and which arc at once seen to be 

 absolutely inapplicable to individual German er Aino crania. 



■|- For cxample for nasal index =100: Bengal data give cephalic index =74, Denniker's data =75; 

 for nasal index =50: Bengal data give cephalic index =79, and Denniker's data =81. The results are 

 less in agrcement if the nasal iudex be prcdictcd from the cephalic.
