10. 15. 20. 25. 30. As, for example,
antoniuse, as one sees in the aforementioned example,
10, 25, 20, and 30; and there [each] carries its number:
10, the o 25, the i 20, and the u 30. This is understood when
they are alone and complete, so that there
be no other of this kind, such as two by two; and
on this occasion they do not have
the said 10, 15, 20, 25, 30. Whereby it is
very rare that one of these vowels remains alone;
and when they are accompanied by three
similar ones, they immediately take the virtue
of unity and lose the Zero, or the tens,
remaining in their order.

This rule assures us that there is
no simple vowel which does not have its
fixed number, such as 10, 15, 20, 25, 30; and
the doubles have 11, 22, 33; and if they are
more than double, the number increases,
such as to 12, to 24, to 36. But if they are
triple and quadruple, they must be assembled.
