NOMENCLATURE AND ANALOGIES 151<br />

large cube.<br />

Now, although each cube is supposed to be coloured<br />

entirely through with the colour, the name of which is<br />

written on it, still we can speak of the faces, edges, and<br />

corners of each cube as if the colour scheme we have<br />

investigated held for it. Thus, on the null cube we can<br />

speak of a null point, a red line, a white line, a pink face, and<br />

so on. <strong>The</strong>se colour designations are shown on No. 1 of<br />

the views of the tesseract in the plate. Here these colour<br />

names are used simply in their geometrical significance.<br />

<strong>The</strong>y denote what the particular line, etc., referred to would<br />

have as its colour, if in reference to the particular cube<br />

the colour scheme described previously were carried out.<br />

If such a block of cubes were put against the plane and<br />

then passed through it from right to left, at the rate of an<br />

inch a minute, each cube being an inch each way, the<br />

plane being would have the following appearances:—<br />

First of all, four squares null, yellow, red, orange, lasting<br />

each a minute; and secondly, taking the exact places<br />

of these four squares, four others, coloured white, light<br />

yellow, pink, ochre. Thus, to make a catalogue of the<br />

solid body, he would have to put side by side in his world<br />

two sets of four squares each, as in fig. 92. <strong>The</strong> first<br />

are supposed to last a minute, and then the others to
