That would involve hooking into the MathJax, which is more learning than
I want to do at present.   There is no need to show progress *within* a
DIV, since no individual set of equations can take more than a very few
seconds.  The most elegant representation would be to show the number of
the most recently-completed page; but MathJax by default shows
percentage done, and there is no need to improve on that.

Reading a single Wooster should be part of one's cultural education.
But I'd not advise reading Wodehouse intensively, unless for example
confined to bed with a disease that makes one _feel_ feeble.

Well, if you can read all of the superscripts ...  For them, it may be
necessary for me to work through the maths, or trust to a later printing
(which Google Books will only show me 2/3 of).  OTOH, I only need to
discover what Euler wrote that he'd proved; and I understand from other
sources (including myself) what he might have proved.  What I want to
know can be encoded as an array of four or five Booleans,

I have saved your example and intend to fit the code when real life
permits - it is an unusually busy week.  It's a pity this group has
dwindled; I have a problem about which Lasse might have expertise.
