4. Nasal breadth.—The greatest diameter, measured without pressure, 
between the wings of the nose. 
5. Nostril length.—The greatest antero-posterior diameter of the 
nostril. 
6. Nostril breadth.—The greatest diameter taken at right angles to 
the diameter of greatest length. 
D. Ear. 
Calliper Measwrements. 
To be taken with contact only. 
1, Length of the ear basis.—The length of the line drawn from the front 
upper insertion point of the auricle to the front lower insertion point 
(E F, figs. 1 and 2).

2. Greatest length of the ear.—(AB, fig. 1.) From the highest to 
the lowest point of the auricle. 
3. Greatest breadth of the ear.—(C D, fig. 1.) The maximum dia- 
meter at right angles to the length-line from the ear basis to the hinder 
border of the auricle. 
4. Distance from the Darwinian tubercle to the wpper border of the 
tragus (X L, figs. 1 and 2). 
The prominence in front of the earhole is the tragus ; the prominence 
behind the earhole is the antitragus. The narrow interval between and 
below these prominences is the inciswra intertragica. 
The Darwinian tubercle is a small projection very frequently present 
on the free edge of the folded border of the hinder part of the ear near 
the summit of the auricle. It is the morphological apex of the ear. 
5. Distance from the highest point of the ear to the bottom of the 
incisura intertragica (AT, fig. 2). 
6. Length of the lobule of the ear—From the bottom of the inciswra 
tntertragica to the lowest point of the auricle,
