Scott. — Osteology of the Maori and JSIoriorl. 53 



Thirty-five bones were measured. The average maximum 

 length of these is 261-6mm., but they vary between 284mm. 

 and 237mm. The eighteen right bones have an average length 

 of 262-4mm. ; the left are slightly shorter, averaging 260-8mm. 



The antero-posterior curve of the upper third of the shaft 

 is more pronounced than in European bones. 



Badio-humeral Index. 



The proportion between the maximum lengths of the 

 humerus and radius is expressed by this index, and is calcu- 

 lated according to the formula — 



Radial length x 100 

 Humeral length 



This I have been able to calculate in twenty cases, taking 

 both right and left arms. In one it is as high as 82-3, in 

 another as low as 72-8, and the average of the set is 77-8. 

 Professor Turner has given this index in two New Zealand 

 skeletons, and these have a mean of 76-5. The mean index of 

 five Polynesians, as given by M. Topinard, is 76. He does not 

 state, however, whether any of these are Maoris. 



Amongst Europeans this index averages between 73 and 

 74. The forearm of the Maori, therefore, is, relatively to the 

 upper arm, longer than it is among the civilised races of 

 Europe. In this respect, however, the Maori is exceeded by 

 the Negro, with an average index of 79, and by a few other 

 savage races. 



Sir William Turner proposes to divide races into three 

 groups, according to the height of this index : Brachykerkic, 

 those with an index below 75 — i.e., with a relatively short fore- 

 arm (Europeans, Esquimaux, &c.) ; dolichokerkic, those with 

 an index above 79 — i.e., with a relatively long forearm (Anda- 

 manese, Negritos, &c.) ; and mesatikerkic, those with an index 

 intermediate (Australians, Negroes, &c.). He places Poly- 

 nesians generally in the middle group, and my measurements 

 show that the Maoris are also mesatikerkic. 



If we now look at the influence of sex on this index, as 

 shown in my table, we find that the series of fourteen males have 

 an average index of 78-7, while the average of the six females 

 is only 74-3. It is possible that the female skeletons examined 

 by me have exceptionally short forearms ; but, as shown by 

 Topinard, '-'= this index in the female is in all races measured by 

 hhn lower than in the male ; and my results, so far as they go, 

 point to this rule holding also amongst the Maoi-is. 



Os Innominatum. 

 The measurements of this bone are given with the descrip- 

 tion of the pelvis.
