The colour of the iris is very important; next in import¬

Colour; —The colour may be denoted in accordance with 
Broca’s scale, which distinguishes four colours—orange or 
brown, ranging from very dark (1), through dark (2), medium 
(3), light (4), to lightest (5) ; green, similarly graduated frotn 
6 to 10 ; blue, from darkest to lightest, 11 to 15 ; and grey 
or violet, from 16 to 20. 
But Topinard’s plan adopted in the Schedule is preferable, 
as being simpler and easier of application. He recognised 
four classes— 
1. Dark.—Including those which are called black- 
brown, dark hazel, &c. 
2. Medium or Neutral.—Such as cannot at once, in a 
good light, be distinguished as light or dark. 
Among these are the dark greys ; most of the 
greens ; those with a predominance of orange 
towards the centre, but of grey or light green 
elsewhere, &c. Examples of Some varieties of 
neutral eyes are given (see Plate III., figs. A, B, 
C, and D). 
' 3.—Other than blue (light grey very light 
Light. < green, &c.). 
4.—Blue. 
What are the relative proportions of these four classes 1 
The eyes should be examined from a moderate distance, so as 
to get a general impression of the colours. Those distinctly 
darker than the neutral examples given to be called dark 
those lighter to be called light
