lie below that which they first occupied. They will come
where the support was on which he stood his first set of
squares. He will get over this difficulty by moving his
support.
Then, since the cubes come upon his plane by the light
yellow face, he will have, taking the null cube as before for
an example, null, light yellow face; null, red section,
because the section is perpendicular to the red line; and
finally, as the null cube leaves the plane, null, light yellow
face. Then, in this case red following on null, he will

have the same series of views of the red as he had of the
null cube.
There is another set of considerations which we will
briefly allude to.
Suppose there is a hollow cube, and a string extended
across it from null to null, r., y., wh., as we may call the
far diagonal point, how will this string appear to the
plane being as the cube moves transverse to his plane?
Let us represent the cube as a number of sections, say
5, corresponding to 4 equal divisions made along the white
line perpendicular to it.
We number these sections 0, 1, 2, 3, 4, corresponding
to the distance along the white line at which they are
taken, and imagine each section to come in successively,
