Height of Head 



The height of the head measured by the writer throughout his 

 investigations on the living, is that from the line connecting the 

 floor of the auditory canals to the scalp over the bregma. The method 

 relied upon and which gives results somewhat higher than those ob- 

 tained by the means of Gray's radiometer, is given briefly in the foot- 

 note. 2 Regrettably both Chantre and Myers in their measurements 

 on the Egyptians used other methods, and their results are not com- 

 parable with those here recorded.

2 The measurement is obtained by a spreading and a sliding compass. The 

 branches of a suitable compas d'epaisseur are introduced well into the audi- 

 tory meati and allowed to rest on their floor. The expansion of the instru- 

 ment is noted, with the scale held over the bregma region ; the distance from 

 the bregma region to the lower edge of the scale is measured by the rod of 

 the compas glissiere, and a simple arithmetical process gives the biauricular 

 line-bregma height. With practice the measurement becomes easy, rapid, and 

 at least as reliable as the measure of the same height by any other method. 

 With due care, particularly as to the temperature of the instrument, the 

 branches of the compass in the ears cause but very little discomfort. The 

 writer has used this method now for many years with satisfactory results, 

 and after testing the Gray's radiometer, must prefer it to that instrument.
