Explanation of Tables 
Table I. Descriptive Characters and Head Measurements , In the case 
of those measurements that are the result of one or more observations* the 
figure recorded is the mean taken to the nearest millimetre* 
Table II. Body and Limb Measurements—Absolute and Relative . This 
table embodies the actual measurements of the bodies and limbs of many of 
the subjects recorded in Table I, the serial numbers referring to one and the 
same individual throughout. In the second column devoted to each person, 
the absolute measurements are reduced to a common standard of stature = 1000. 
In performing the necessary calculations a lo-inch slide-rule has been employed, 
and the results are correct to within two parts per mille. 
When there is a double measurement, as in the case of the arms and feet, 
the mean of the two sides of the body has been adopted, as the methods of 
measurements were not sufficiently rigorous to show, with any degree of 
accuracy* the real amount of bilateral asymmetry present. 
The formulae for the indices given at the bottom of the page are as 
follows :—

Table III. Cranial , Nasal\ and Aural Indices , The indices have been 
calculated by the methods used for Table II, and are accurate within the 
same limits. It is unnecessary to give the formulae for the indices which are 
in universal use, except, perhaps, that for the biorbito-nasal, which is the ratio 
between the distance between the external margins of the orbits measured 
with a tape across the bridge of the nose and the same measured with the 
callipers. 
The other tables explain themselves. 
(The immense labour of preparing the tables of measurements and indices 
in the present and the subsequent parts of this section is due, almost entirely, 
to my collaborator.—N. A.).
