The author has shown in Craniometric Study no. 29 that a very definite and indeed favorable correlation existed between the interorbital width and the nasal width in all the racial types representative of modern man that he was enabled to study. His obvious course, therefore, was to ascertain the possible existence of a correlation between the interorbital width/facial height index and the nasal index, in which these two transverse cranial dimensions participate. The present research is thus to be regarded as a direct sequel to the researches recorded in Craniometric Studies nos. 29 and 30.
The author has shown in Craniometric Study no. 30 that among all the racial types that were available for study, the average interorbital width/facial height index reached its lowest ebb in the Greenland Eskimo crania. His obvious course, therefore, was to ascertain the condition shown by the nasal index in that racial group. For that purpose he had the benefit of the data recorded in Hrdli6ka 's catalogue,' which gave 42.9 as the average nasal index for these Eskimo male crania. The writer then searched through HrdliEka's three catalogues(1, 2, 3), and was interested to note that this average was the lowest for all the very diverse racial types con-' The writer noted that Turner gave 38.9 as the average nasal index for these Scottish male crania in table XVI of his monograph. This was obviously a typographical error, a s the range of variation of the index in this cranial group was from a maximum of 53.7 to a minimum of 38.8. The present writer accordingly recalculated the average for the index from the eighty male crania listed in tables I to XV of Turner's paper. This proved to be 44.4, which, as it happened, was exactly the same as the average nasal index for the female Scottish crania, as given by Turner.
