Pointing the number off in the manner described, it is seen that there
are _two_ figures in the first section—viz., 14. Setting the cursor to
14 on the R.H. scale of A, the slide is moved to the right until it is
seen that 241 on the L.H. scale of B falls under the cursor, when 241 on
D is under the L.H. index of C. Pointing 14,000 off into sections we
have 14 000—that is, _two_ sections. Therefore, there are two digits in
the root, which in consequence will be read 24·1 [24·1014+].
