TABLE XIV. Ordination of vertico-transverse indices. Salado. 



TABLE XV. Of the vertico-transverse indices of all the skulls. Salado. 



Minimum index, 77.70; maximum index, 97.29. Neither of these two indices come in the 

 normal series, as the minimum is that of a child, the maximum aberrant. They therefore do iiot 

 appear in the ordination. 



TABLE XVI. Ordination of the apparently normal skills, with reference to the differences betir een 

 their respective cephalic and vertico-transverse indices, expressed in per cent of the greatest 

 leng th. Salado. 



[The sign + indieates that the cephalic inilex is greater than the vertico-transverse. The sign indicates that the vertiro-transverae index 



is greater than the cephalic.] 



Variation, 9.90. Theoretical mean of variation, 4.38. Skull nearest to mean, IT. 15. This 

 skull then shows what may be arithmetically regarded as a typical relation of vertico-transverse 

 and cephalic indices.
