It's a special English form that is relatively rarely used.  But it is
nevertheless correct.

In the Texinfo source.  I show it below:

  @c This and the next paragraph say ``kinds of atom'', but that is not
  @c a typo, just slightly ``old-fashioned wording which adds a fillip
  @c of interest to it'', and ``is more elegant writing'', according to
  @c RMS.

As you see, I consulted with Richard Stallman about this issue,
because I had a gut feeling the original wording was correct, but
wasn't sure.  Bob Chassell, who wrote that manual, always used 100%
correct English.
